Jarrett Allen has become the latest Cleveland Cavalier to sign a maximum contract extension since the conclusion of the 2023-24 NBA season.

Allen signed a three-year, $91million extension with the Cavaliers on Wednesday, according to multiple sources.

The deal will guarantee him $131million over the next five years.

Allen joins Donovan Mitchell and Evan Mobley as Cleveland players to ink extensions this off-season, as the franchise has established itself as a legitimate contender in the Eastern Conference.

The 26-year-old Allen averaged a career-best 16.5 points along with 10.5 rebounds in 77 games last season. His shooting percentage of 63.4 ranked fourth in the NBA.

The 22nd overall pick of the 2017 draft by the Nets, Allen spent his first three-plus NBA seasons in Brooklyn before Cleveland acquired him in January 2021.

He was named an All-Star in his first full season with the Cavs in 2021-22, when he averaged 16.1 points and a career-high 10.8 rebounds.

In 252 games in a Cavs uniform, Allen has averaged 15.1 points, 10.3 boards and 2 assists while shooting 64.2 per cent.

The Cavs reached last season's East semi-finals before being ousted by the eventual champion Boston Celtics with Allen sitting out the entire play-off series due to a rib injury and Mitchell missing the final two games because of a left calf strain.

In the four post-season games he played before his injury, Allen averaged 17 points on 67.6 per cent shooting and 13.8 rebounds.

Jayson Tatum credited the Cleveland Cavaliers for the fight they showed in Donovan Mitchell's absence after helping the Boston Celtics take a 3-1 lead in the teams' Eastern Conference semifinal series. 

Tatum had 33 points and 11 rebounds as the Celtics moved within a game of reaching the conference finals for a third straight year with Monday's 109-102 road win.

Cleveland, who were already without starting center Jarrett Allen due to a rib contusion, were also deprived of their leading scorer after Mitchell suffered a calf strain in Game 3.

However, the Cavs stayed in the game until Jaylen Brown sank a clutch 3-pointer with 69 seconds to go in the fourth quarter, with Derrick White and Tatum then making a couple of free throws each to add some gloss to the scoreline.

Darius Garland had 30 points and seven assists for the Cavs while Caris LeVert had 19 points, leaving Tatum impressed. 

"It's to be expected, right? When the best player goes out, everybody has more freedom, more opportunity," Tatum said of Boston's opponents.

"Obviously, we knew it wasn't going to be easy. It's the playoffs, they don't want to go home. 

"Give them credit, they played hard from beginning to end and made big plays on both ends. They hit big shots, so it was a battle, and it was fun out there."

Cavs coach J.B. Bickerstaff also heaped praise on his players, saying: "I mean, they laid it all out there. They gave us everything that they had. 

"They competed at a high level. They played the game properly. I'm proud of the guys, the way they went out and scrapped and competed and gave ourselves a chance."

Boston now have a chance to wrap up the series in Game 5 at TD Garden on Wednesday, an opportunity Brown is keen to ensure they take.

"There's nothing better than winning a playoff game on the road," Brown said. "It's like everybody's against you guys. It's a tough environment, the crowd was great, but as a competitor, it's really fun to be in an environment like that, to win on the road.

"Now it's time to go back and play well in front of our fans and give them something to cheer for and try to get a win."

Shai GIlgeous-Alexander scored 22 of his 34 points in the second half to rally the Oklahoma City Thunder from a 14-point deficit and earn a crucial 100-96 victory over the Dallas Mavericks in Monday's Game 4 of a Western Conference semifinal series.

Chet Holmgren had 11 of his 18 points after half-time and added nine rebounds to help the top-seeded Thunder even the best-of-seven series at 2-2 as it heads back to Oklahoma City for Wednesday's all-important Game 5.

The fifth-seeded Mavericks squandered an opportunity to put the Thunder on the brink of elimination despite setting a franchise play-off record with 13 blocks, including four each from Derrick Jones Jr. and rookie Dereck Lively II.

Jones finished with 17 points in the loss, while Luka Dončić registered a triple-double for Dallas with 18 points, 12 rebounds and 10 assists. 

The Mavericks led the majority of the game and owned an 86-80 advantage just past the midway point of the fourth quarter before Oklahoma City began its late surge. The Thunder seized momentum with a 12-2 run, capped by consecutive 3-pointers from Holmgren and Luguentz Dort, to go up 92-88 with 2:14 remaining.

Dallas answered on Tim Hardaway Jr.'s 3-pointer on the ensuing possession, but back-to-back baskets by the Thunder's Jalen Williams gave Oklahoma City a 96-91 lead entering the final minute.

The Mavericks again responded and had a chance to tie it when Doncic was fouled with 10.1 seconds left with Dallas trailing 96-94. The MVP finalist made just one of his two shots, however, and the Thunder sealed the outcome by going 4 for 4 from the foul line in the waning moments.

Free throw shooting played a part in the result, as Oklahoma City finished 23 of 24 from the line compared to 12 of 23 for Dallas.

The Mavericks held a 54-43 lead at half-time after limiting the Thunder to under 35 per cent shooting for the first two quarters, and stretched the margin to 14 when P.J. Washington hit a 3-pointer to begin the third.

Oklahoma City closed the gap before the end of the period, though, as it ended the third quarter on a 9-2 run to pull within 69-65 entering the fourth.

Celtics handle injury-plagued Cavaliers to take 3-1 lead

In the East, the top-seeded Boston Celtics moved within a game of reaching the conference finals for a third straight year after posting a 109-102 Game 4 win over the shorthanded Cleveland Cavaliers behind Jayson Tatum's 33 points and 11 rebounds. 

Jaylen Brown added 27 points to help Boston take a 3-1 series lead over a fourth-seeded Cavaliers team playing without leading scorer Donovan Mitchell. The All-Star guard was unavailable due to a strained left calf he sustained in Cleveland's 106-93 loss in Saturday's Game 3.

The Cavaliers also remained without starting center Jarrett Allen, who hasn't played since Game 4 of their opening-round series against Orlando due to a rib contusion.

Darius Garland kept Cleveland competitive by producing 30 points and seven assists, while Caris LeVert had 19 points starting in place of Mitchell.

Boston can close out the series at home in Wednesday's Game 5.

Tatum set the tone right from the outset, scoring 16 points on 6-of-9 shooting in the first quarter to stake the Celtics to a 37-30 lead after one period.

The All-Star forward closed out the first half with a 3-pointer that sent Boston into the break with a 62-57 advantage, though Cleveland opened the third quarter on an 8-2 run to move ahead by a 65–64 score three minutes into the second half.

Boston re-asserted control from there, however, as it outscored the Cavs by a 14-4 margin over the next 4 1/2 minutes. Brown had seven points during the spurt, which Derrick White capped with a 3-pointer for a 78-69 Celtics' lead with 4:50 left in the third quarter.

The Celtics stretched the lead to 98-83 with under eight minutes left, though Cleveland kept battling and put together a 12-2 run to close the gap to 100-95 with three minutes left to play.

Brown hit a clutch 3-pointer with 1:09 to go, however, to put Boston up 105-97, and the Celtics kept Cleveland at bay the rest of the way as White and Tatum each made two free throws in the closing stages.

Donte DiVincenzo's go-ahead 3-pointer with 13.1 seconds left highlighted a furious late rally that propelled the New York Knicks to a crucial 104-101 win over the Philadelphia 76ers in Monday's Game 2 of an Eastern Conference quarter-finals series. 

Down 101-96 in the final minute, the second-seeded Knicks scored the game's final eight points to grab a 2-0 lead in the best-of-seven series, which shifts to Philadelphia for Thursday's Game 3.

DiVincenzo finished with 19 points and Jalen Brunson had 24 along with eight rebounds and six assists for New York, which also got a big effort from center Isaiah Hartenstein to overcome a 10-point deficit late in the first half.

Hartenstein scored all 14 of his points in the second half on 7-of-7 shooting while helping the Knicks contain 76ers' star Joel Embiid. The reigning NBA MVP managed 34 points and 10 rebounds, but made good on just 12 of 29 field goal attempts and missed a potential tying 3-point try at the buzzer.

Tyrese Maxey ended just shy of a triple-double for seventh-seeded Philadelphia, as he compiled 35 points, 10 assists and nine rebounds.

The Sixers trailed 90-82 early in the fourth quarter before outscoring New York 19-6 over a seven-minute stretch to pull ahead late. Maxey's jumper with 2:22 to go gave Philadelphia a 97-96 edge, and the All-Star buried a 3-pointer shortly afterward to extend the lead to four entering the final minute.

Brunson gave New York some life with a 3-pointer with 27.4 seconds remaining to cut the lead to 101-99, and after Maxey turned it over on the ensuing possession, DiVincenzo knocked down a 26-footer on a second-chance attempt to send the Knicks in front.

Maxey then couldn't get a contested layup to fall with 6.6 seconds left, and New York's OG Anunoby was fouled after grabbing the rebound before making both free throws ahead of Embiid's game-ending miss. 

Nuggets rally from 20 points down to stun Lakers in Game 2

The Denver Nuggets also took a 2-0 lead in their Western Conference series with the Los Angeles Lakers after overcoming a 20-point second-half deficit to rally for a stunning 101-99 win.

Jamal Murray capped Denver's improbable comeback by hitting a game-winning 15-foot jumper with 0.4 seconds left on the clock.

Murray scored 16 of his 20 points in the second half and Nikola Jokić had 15 points after half-time to also spark the defending NBA champions. Jokic ended the night with a 27-point, 20-rebound, 10-assist triple-double.

Anthony Davis finished with 32 points and 11 rebounds for the seventh-seeded Lakers, who appeared on the verge of sending the series back to Los Angeles all tied up after opening up a 68–48 lead two minutes into the third quarter.

Second-seeded Denver trailed 74-55 near the midway point of the third before getting back in it with a 10-0 run. The Nuggets later went on a 10-1 spurt to pull within 83-81 on Murray's layup with 6:45 remaining.

Murray was later fouled with 57.6 seconds left and made both free throws to forge a 97-97 tie. LeBron James answered with a layup on the ensuing possession to put Los Angeles back ahead, but Murray sunk a step-back jumper with 30 seconds remaining to even the score once again.

James then misfired on a 3-point try and the Nuggets secured the rebound before getting the ball to Murray, who knocked down the game-winner right before the buzzer sounded with Davis contesting the shot.

James had 26 points and 12 rebounds, while D'Angelo Russell netted 23 points for the Lakers while going 7 of 11 from 3-point range.

Game 3 will take place Thursday night.

Cavaliers shut down Magic again to take 2-0 series lead

Donovan Mitchell scored 23 points and Jarrett Allen led another strong defensive effort for the Cleveland Cavaliers, who took a 2-0 lead in their first-round series against the Orlando Magic by recording a 96-86 win.

After holding the Magic under 33 per cent shooting in Saturday's series opener, fourth-seeded Cleveland forced 17 turnovers and limited No. 5 seed Orlando to a 36.2 per cent rate from the field to move within two wins of advancing.

Allen particularly made his presence felt by corralling 20 rebounds along with three blocks and two steals. The standout center also contributed 16 points on 6-of-10 shooting.

Evan Mobley added 17 points and Darius Garland had 15 in a game the Cavaliers never trailed while taking control early by building a 30-18 lead after one quarter.

Cleveland's margin grew as high as 17 points in the second quarter as the Magic continued to struggle to score, and Mitchell registered 19 of his points in the first half to help send the Cavs into the break owning a 58-44 advantage.

Orlando never seriously threatened in the second half and will now attempt to reverse momentum when it returns home to host Game 3 on Thursday. 

Paolo Banchero led the Magic with 21 points and Franz Wagner had 18 for Orlando, though all but one of those points came during the first half.

Giannis Antetokounmpo scored 33 points and grabbed 13 rebounds as the Milwaukee Bucks held off the West-leading Minnesota Timberwolves 112-107 on Friday in a matchup of NBA heavyweights.

Damian Lillard had 21 points, 10 assists and a season-high nine rebounds and Malik Beasley scored all 14 of his points in the third quarter as the Bucks improved to 4-10 under new coach Doc Rivers.

Anthony Edwards scored 28 points and hit three 3-pointers in the final two minutes to draw the Wolves within 110-107 with 31 seconds left, but Lillard’s long jumper 22 seconds later sealed the win.

Karl-Anthony Towns had 22 points with 14 rebounds and Rudy Gobert added 12 points and 19 boards for Minnesota, which had a four-game winning streak snapped.

Butler among 4 ejected in Heat’s win

Jimmy Butler was one of four players ejected after a fourth-quarter scuffle and the Miami Heat held off the New Orleans Pelicans, 106-95.

Butler had 23 points and nine rebounds and Bam Adebayo added 24 points for Miami, which snapped New Orleans’ four-game winning streak and made it seven consecutive wins over the Pelicans.

Also ejected for the melee were Heat reserve Thomas Bryant and Jose Alvarado and Naji Marshall of the Pelicans.

Herb Jones scored 19 points and Jonas Valanciunas had 12 with 10 rebounds for New Orleans, which couldn’t overcome 37.5 percent shooting, including 7 of 32 from 3-point range.

Maxey leads 76ers over Cavaliers

Tyrese Maxey scored 24 points and Cam Payne added 16 off the bench to propel the Philadelphia 76ers to a 104-97 victory over the Cleveland Cavaliers.

Maxey came alive in the fourth quarter, scoring 15 of the Sixers’ final 20 points and assisted on a 3-pointer by Buddy Hield that put Philadelphia up by eight in the final minute.

Maxey was the only Sixer to make more than one basket in the fourth quarter and also added four rebounds and two assists.

Jarrett Allen had 24 points and Darius Garland added 20 and nine assists, but Cleveland had a six-game road winning streak stopped while losing for the third time in four games overall.

Recent acquisition Buddy Hield scored 24 points and the Philadelphia 76ers held on late to end the Cleveland Cavaliers' nine-game winning streak with Monday's 123-121 victory.

Despite still being without injured reigning NBA MVP Joel Embiid, Philadelphia handed the red-hot Cavaliers just their second loss in their last 19 games behind hot-shooting efforts from Hield and Kelly Oubre Jr. 

Hield, making his third appearance since being acquired by the Sixers from the Indiana Pacers on Thursday, finished 5 of 8 from 3-point range and 9 of 13 overall from the field. Oubre hit 10 of his 14 field goal attempts while also collecting 24 points.

The win was Philadelphia's second straight following a 1-8 stretch from Jan. 25-Feb. 9, during which the team lost Embiid for an extended period due to a knee injury that required surgery.

Cleveland got 36 points and six assists from All-Star Donovan Mitchell and 21 points and 10 rebounds from Jarrett Allen, but couldn't match the Sixers down the stretch after taking a 102-100 lead with seven minutes remaining.

Hield scored the final eight points of a 13-2 run that gave Philadelphia a 113-104 advantage with 4:28 left to play, and the 76ers led 120-110 with 1:25 to go following an Oubre 3-pointer.

The Cavs responded with a 9-0 spurt to pull within 120-119 on Mitchell's 3-pointer with 14 seconds remaining, and had a chance to win at the buzzer when Darius Garland launched a 3-point shot that just missed the mark.

Garland ended with 21 points and nine assists, while Tyrese Maxey recorded 22 points and nine assists for Philadelphia.

Timberwolves dominate second half in rout of Clippers

The Minnesota Timberwolves got 24 points from Karl-Anthony Towns and a big third quarter to pull away for a 121-100 win over the Los Angeles Clippers and pad their lead atop the Western Conference.

Anthony Edwards added 23 points, 12 of which came during a dominant third quarter in which the Timberwolves outscored Los Angeles by a 40-19 margin.

Minnesota entered Monday's clash owning a slim half-game advantage on the Clippers, Oklahoma City Thunder and Denver Nuggets, who were handed a 112-95 defeat by the Milwaukee Bucks, in the tightly bunched West standings. 

The Clippers kept it close until the latter stages of the third quarter, as the Timberwolves held a 70-69 edge with under five minutes left in the period.

Minnesota took over from there, as it closed out the quarter on a 19-3 run to take a commanding 89-72 lead into the fourth. Towns had eight points during the pivotal spurt.

The Timberwolves maintained a lead of 15 points or more throughout the final period en route to posting a second straight win and giving Los Angeles a second loss in its last three games.

Kawhi Leonard and Paul George led the Clippers with 18 points each, while James Harden finished with 17 points and six assists. 

Bucks use defence to get past champion Nuggets

The Milwaukee Bucks got 36 points and 18 rebounds from Giannis Antetokounmpo and another strong performance from their much-maligned defence to hand the defending NBA champion Denver Nuggets a 112-95 loss.

Milwaukee entered Monday's marquee matchup ranked 23rd in the NBA in scoring defence at 119.3 points allowed per game, but held the formidable Nuggets to their second-lowest shooting rate of the season at 38.3 per cent.

The Bucks have yielded under 100 points in consecutive games for the first time this season. Milwaukee lost five of its first six outings under new head coach Doc Rivers prior to Friday's 120-84 rout of the Charlotte Hornets.

Nikola Jokić amassed 29 points, 12 rebounds and eight assists for the Nuggets. Jamal Murray and Michael Porter Jr., Denver's second and third-leading scorers on the season, were a combined 4 of 16 from the field, however.

Murray managed just three points on 1-of-5 shooting before sitting out the second half due to inflammation in his lower legs.

The Bucks had built a comfortable 60-44 lead at that point as Antetokounmpo racked up 26 points on 10-of-12 shooting over the first two quarters. The Nuggets never got their deficit under 13 points the rest of the way and are now mired in a two-game losing streak.

The Memphis Grizzlies will get a chance to tie their longest winning streak in franchise history when they host the Cleveland Cavaliers on Wednesday.

Monday's 30-point demolition of the Phoenix Suns extended the Grizzlies' streak to 10, and they are now one victory away from tying the 11-game streak from the 2014-15 campaign starring Marc Gasol and Zach Randolph, which was matched last season.

Over their last 10 fixtures, the Grizzlies have been a juggernaut on both ends of the court, scoring 119.9 points per 100 possessions to sit third in offensive rating, while also boasting the best defense in the NBA, allowing just 106.5.

Meanwhile, the team the Grizzlies overtook to snatch top spot in the defensive rankings was the Cavaliers, who still sit second for the season.

Another key indicator for the true contenders is net rating – which measures how much better a team's offensive rating is compared to their defense – and both of these sides have excelled through the first half of the season. The Grizzlies sit second overall with a net rating of 5.8, while the Cavaliers are third at 4.7.

Two very similar teams, both the Cavaliers and the Grizzlies utilise two defensive anchors in their starting line-up, leaning away from the more prevalent "small ball" roster constructions seen around the league.

For the Grizzlies, Steven Adams is arguably the strongest rebounder in the league while Jaren Jackson Jr leads the NBA in blocks per game at 3.3. On the Cavaliers' side, All-Star Jarrett Allen and defensive prodigy Evan Mobley roam the interior.

While these sides are almost identical defensively, the way they attack on offense, particularly through their star players, could decide their fate.

Grizzlies point guard Ja Morant is, without a doubt, one of the best guards in league history when it comes to finishing at the rim. He is averaging five makes per game within five feet of the basket – the only guard in the league to do so – while converting at a terrific 61 per cent clip.

The problem with that is how well both of these teams protect the basket, as it creates the question of what happens when an unstoppable force – Morant – meets an immovable object – the rim protection of Allen and Mobley.

On the other hand, the combination of Darius Garland and Donovan Mitchell for the Cavaliers are far more malleable with the way they create their offense.

Garland excels in 'floater range' from five-to-nine feet away from the hoop, sitting 15th in the league with 1.3 makes per game at an efficient 50 per cent, while Mitchell provides the long-range assault.

Mitchell is averaging 3.1 makes per game on deep threes (greater than 25 feet), which trails only the Golden State Warriors' Splash Brothers, Stephen Curry (3.8) and Klay Thompson (3.2).

It should be a mouthwatering clash between the league's best two defensive teams, who both have all their young stars healthy and ready to go as they look to strengthen their playoff positions.

PIVOTAL PERFORMERS 

Cleveland Cavaliers – Jarrett Allen

It is no secret that Morant is the driving force behind the Grizzlies' success, and for him to dominate games, he needs to control the paint.

Allen is the Cavaliers' primary rim protector and will be tasked with preventing Morant from producing more of his highlight-reel finishes, and if he can turn Morant into a jump-shooter for the night, Cleveland will consider that a massive win.

Memphis Grizzlies – Desmond Bane

Desmond Bane is the perfect counterbalance to Morant, providing the Grizzlies with a dynamic shooting threat who holds the defense's attention at all times.

Through three seasons, Bane owns a ridiculous career three-point percentage of 43.3. It is not just a strong number, it is the seventh-best career figure of all-time, and places him in the absolute top echelon of shooters in today's game.

If he can hit a couple early and force the Cavaliers' defense to divert some of their attention away from Morant, Bane could open up everything for the Grizzlies' offense.

KEY BATTLE – Can the Cavaliers figure out how to win on the road?

Heading into this contest, both the Grizzlies (19-3) and the Cavaliers (19-4) sit top-three in the NBA's best home records.

The Grizzlies will get the honour of hosting this time, leaving the Cavs as the underdogs as they try to figure out what is behind their disappointing 9-13 record away from home this campaign.

HEAD-TO-HEAD

This will be the first time this season these two teams meet, although the Grizzlies have won each of the past three matchups.

The Cavaliers defeated the Grizzlies once during Morant's rookie season in 2019, but the former Rookie of the Year has not lost to them since.

The Cleveland Cavaliers and the Milwaukee Bucks have each contended for and won titles in the past 10 years, but they have very rarely both been good at the same time.

LeBron James led the Cavaliers to four straight NBA Finals between 2014-15 and 2017-18 as they enjoyed an epic rivalry with the Golden State Warriors.

But Cleveland were tied for the second-worst record in the league the following year, with James in Los Angeles, as Central Division rivals Milwaukee came to prominence with the NBA's best record in Giannis Antetokounmpo's first MVP year.

The Bucks have since had control of the division and again lead the Eastern Conference through 30 games at 22-8.

Yet now there is a challenge from the Cavs, who are a competitive 21-11 and have won four straight games ahead of hosting the Bucks on Wednesday.

Having already shown real signs of progress last year in reaching the play-in tournament, Cleveland have kicked on again after a trade for Donovan Mitchell that they hope will turn them into a serious player in the East.

So far, that looks to be the case, with Mitchell's career-high 29.3 points per game leading the team – and ranking eighth in the NBA – while he has produced in big games against the Boston Celtics.

The Cavs are 2-0 against the second-placed Celtics this season; however, they are 0-2 against the Bucks, who will be intent on batting away their division rivals ahead of Christmas.

PIVOTAL PERFORMERS

Cleveland Cavaliers – Jarrett Allen

The Cavaliers will hope the physicality of Allen can be the missing piece against the Bucks. He has played only 12 minutes against Milwaukee so far this season, absent for the first game and withdrawn injured in the second having scored only a single point.

Since returning from that hip injury earlier this month, Allen has averaged 14.9 points and 9.3 rebounds, with 26 rebounds across his past two outings.

Milwaukee Bucks – Giannis Antetokounmpo

Nobody likes playing against Antetokounmpo, but only against the Brooklyn Nets and the Utah Jazz has he averaged more points per game across his career than against the Cavaliers.

Although the Cavs have spoken of Evan Mobley having the potential to become a player in the Giannis mould, neither he nor his team-mates have a fix for the 'Greek Freak' when he is in form – as he was in scoring 38 points in their last meeting.

KEY BATTLE – Can Cavs keep focus after halftime?

Two of the Cavaliers' three worst quarters this season in terms of points differential were the two third quarters they have played against the Bucks. They represented two of Milwaukee's four best quarters of the year.

The Cavs, again on a four-game winning run, had dominated the first half of the teams' most recent meeting, up by 11 before losing the third quarter 35-10 as they were blown away by the Bucks' title0calibre intensity.

Cleveland must show they are capable of going toe-to-toe with such opposition if they are to be a genuine threat this season.

HEAD-TO-HEAD

The Cavaliers may have struggled badly in Milwaukee this season, but they won their final two home games against the Bucks last year, providing hope of another win at Rocket Mortgage FieldHouse, where they are a league-leading 15-2 in 2022-23.

The Bucks have a 130-97 all-time lead in the series, although the Cavs have a 60-53 advantage in Cleveland.

Three-time All-Star Donovan Mitchell admitted his preseason debut for the Cleveland Cavaliers was "definitely weird" following his blockbuster offseason trade from the Utah Jazz.

Mitchell left the Jazz after five seasons in Salt Lake City, opting against a move to the New York Knicks to join an exciting Cavs line-up where he will play in the backcourt alongside Darius Garland.

The Cavs also boast All-Star Jarrett Allen and 2021-22 Rookie of the Year runner-up Evan Mobley along with veteran Kevin Love, offering hope of their first playoffs campaign since 2017-18.

Mitchell played 19 minutes, scoring 16 points on six-for-nine shooting, including three three-pointers along with five assists, in the Cavs' 113-112 loss to the Philadelphia 76ers in his first outing for his new franchise.

"Today, I just kind of sat there and had one of those moments where you sit there and look out and see everything, and it's like, 'Wow. It's really here'," Mitchell said.

"Then once you get on the court, basketball is basketball. But all the little things, it's definitely weird. A little different. But I'm excited. It's going the way I thought it would, in a good way.

"It just didn't feel real… it still didn't hit me yet."

Cavs head coach J.B. Bickerstaff was pleased with Mitchell's initial cohesion alongside All-Star point guard Garland.

"I thought it was pretty seamless," Bickerstaff said. "The way they played together, the way the ball moved, everybody got involved.

"As long as we play in the same style we want to play, where it isn't just based on one guy, but based on the team, I think it's going to work out well for us."

The Cavs finished last season with a 44-38 record, missing the playoffs after losing in the Play-In Tournament to the Atlanta Hawks in the number eight seed game.

Jarrett Allen could be a possible inclusion for the Cleveland Cavaliers when they face the Atlanta Hawks on Friday.

The Athletic's Shams Charania reported Allen, who has been out since March due to a fractured finger, has not been ruled out for Friday despite being listed by Cleveland as questionable.

Following their 115-108 loss to the Brooklyn Nets on Tuesday in their opening play-in game, the Cavaliers now face a must-win situation to keep their season alive.

The 23-year-old All-Star averaged 16.3 points, 10.9 rebounds and 1.7 assists per game and held a career-best net rating of +26 before the injury, sustained in March against the Toronto Raptors, with the Cavs ending the regular season with a 7-11 record from that point.

Allen's inclusion would give Cleveland renewed flexibility with their rotation, using Lauri Markkanen and Evan Mobley in different defensive matchups on the back of Allen's rim protection.

With a win on Friday, JB Bickerstaff's side would secure a first-round playoff matchup against the Miami Heat, the Eastern Conference's first seed.

The Cleveland Cavaliers have confirmed All-Star center Jarrett Allen will be sidelined indefinitely after being diagnosed with a left middle finger fracture.

Allen suffered the injury in Sunday's 104-96 win over the Toronto Raptors that improved the Cavs' record to 37-27.

The 23-year-old only played 10 minutes, scoring six points with two rebounds, before sustaining a quad injury that forced him out of the game, with the finger issue later emerging.

"A CT scan administered today at Cleveland Clinic Sports Health revealed a fracture and he will undergo additional evaluation and treatment," the Cavs said in a statement on Monday.

"No timetable has been set for his return to basketball activities and his status will be updated as appropriate."

Allen has been a key part of the Cavs' surprise playoffs push, averaging 16.1 points, 10.8 rebounds and 1.3 blocks this season.

The Cavs are already missing Collin Sexton (knee), Caris LeVert (foot) and Rajon Rondo who was signed after Ricky Rubio's season-ending ACL injury.

Allen got his maiden All-Star call-up this season as a replacement for the injured James Harden.

James Harden will miss the All-Star Game due to a left hamstring injury, with Jarrett Allen selected as his replacement. 

After joining the Philadelphia 76ers in a blockbuster trade that sent Ben Simmons to the Brooklyn Nets, Harden was ruled out until after this weekend's All-Star break. 

The 2018 NBA MVP had been selected as a reserve but will not feature in the game as he continues to recover from his hamstring issue. 

Harden joined up with his new team-mates in Philadelphia for practice on Monday but will not play against the Boston Celtics or Milwaukee Bucks this week. 

Cleveland Cavaliers center Allen was named as Harden's replacement for Sunday's game at Rocket Mortgage Fieldhouse by NBA commissioner Adam Silver. 

It will be Allen's first appearance in the All-Star Game and he will be part of Team LeBron. Cavs team-mate Darius Garland will line-up opposite him for Team Durant. 

The 23-year-old is averaging career highs of 16.2 points and 11.1 rebounds this season. He is ninth in the league for rebounds per game and 13th in blocks per game. 

The NBA season is heating up nicely.

The Phoenix Suns are on fire, the Golden State Warriors are hanging on their coattails, while defending champions the Milwaukee Bucks are fighting back after a slow start to their season.

Meanwhile, the Detroit Pistons and Oklahoma City Thunder cannot buy a win.

Those are the teams, but which players have been impressing, and which are struggling to make an impact? Stats Perform delves into the numbers with the latest edition of NBA Heat Check.

RUNNING HOT...

Luguentz Dort

It is a team game, which Luguentz Dort knows only too well as his increasingly impressive individual numbers are doing little to turn around the fortunes of the Thunder.

The shooting guard failed to score more than 17 points in any of October's games, but came back from missing the defeat to the LA Clippers on the first day of November determined to do something about his team's form.

Dort set about trying to help the Thunder recover from a slow start and managed seven games of over 20 points, including 34 in the win against the Houston Rockets. Unfortunately for him and his teammates, there have been no wins in seven since then, despite the Canadian's best efforts.

His increased total points per game of 11.7 in October to 19.2 in November is the most in the league, while he was fourth for increase in three-pointers made per game (1.2 to 2.8).

Without that leap in form from the 22-year-old, you wonder how much worse Oklahoma City's record would be right now.

Jarrett Allen

The Cleveland Cavaliers have been a streaky team so far this season, but in Allen they have someone who is showing himself to be a real difference maker.

Allen's numbers have increased almost identically to Dort's, with an average of points scored per game going up from 11.7 to 19.0 from October to November.

The 23-year-old also tops the charts for largest increase in total rebounds per game, going from 9.0 in October to 12.8 in November.

The Cavs won six of their first seven games in November, only to then lose their next five, the first three of which against the Celtics, the Nets and the Warriors they were without Allen through illness.

His return has eventually seen form turn back around, with wins against the Magic and the Mavericks followed up by another at the Heat to kick off December.

Jordan Poole

Three-pointers are an increasingly important part of the modern game, and there is little more satisfying than seeing the ball sunk all the way from downtown.

Golden State Warriors fans may be the only ones getting a little bored of them given how many they see these days, with Steph Curry still the king of three-points, but Poole has been more than holding his own with his 51 total this season seeing him only behind Curry (77), Buddy Hield (61) and Lonzo Ball (52) in the standings.

It is Poole's improvement that gets him onto this list, though, having averaged just 1.5 successful three-point attempts per game in October, he upped that to 3.4 in November, the joint-highest league increase with Luka Doncic.

He was also fifth most improved for points scored, going from 14.0 per game in October to 20.3 in November.

This has helped the Warriors to a strong 18-3 record so far, but he even managed to stand out in the recent defeat to the Phoenix Suns, sinking six three-point attempts in a total contribution of 28 points on the night.

GOING COLD...

Kemba Walker

It was all set up to be a feel-good story before the season began as Walker, born in the Bronx, returned to New York to play for the Knicks after years of success with the Charlotte Hornets and Boston Celtics.

The four-time All-Star got off to a promising start, with eight defensive rebounds against his former Celtics in a debut win, and scoring double figures in all six of his October games.

However, November was not so kind to the 31-year-old, with his average of 3.7 three-pointers per game going down to just 1.3, the largest decrease in the league, and only managing double figures in four of his 12 outings.

Walker has never averaged less than his current 11.7 points per game across a season, with a career average of 19.7.

Such has been the drop in form for Walker, Knicks coach Tom Thibodeau took the difficult decision to remove him from rotation ahead of the game at the Nets at the end of the month. 

Spencer Dinwiddie

The Washington Wizards point guard started the season with some impressive outings after his arrival from the Brooklyn Nets, including contributing 34 points in his second game against the Indiana Pacers, and scoring 20 or more in three of his five games in October. 

During November, Dinwiddie managed to score 20 or more just twice in 13 games, including failing to add anything to the scoreboard in defeat at the Charlotte Hornets.

His has been the largest decrease in points scored per game across the two months, going from an average of 19.8 in October to 12.8 in November.

The Wizards have not been too inconvenienced by this downturn in form from Dinwiddie, sitting second in the Eastern Conference on 14-8, but coach Wes Unseld Jr would surely love to see the 28-year-old return to his early season showings before too long.

Bam Adebayo

The Miami Heat center is averaging a career-best 18.7 points, along with 10.2 rebounds per game.

However, that number of rebounds has decreased from an average of 14.0 per game in October to 8.7 in November. Still respectable but the second-highest decrease of the month in the league behind only Gorgui Dieng (7.2 to 1.8). 

After registering double figures for rebounds in four of his five October performances, Adebayo only managed to do so in five of his 13 games in November, and unfortunately for him is set to miss the entirety of December after picking up a thumb injury.

The Heat won six of their first seven games, and Adebayo's electric form was a large part of that strong start, but having taken just two victories from their last six outings, will be hoping that when the Olympic gold medallist returns in the New Year, he can rediscover those elite levels.

Coach J. B. Bickerstaff lauded Evan Mobley's "will to win" after the rookie "stepped up big" in the Cleveland Cavaliers' stunning comeback victory against the Boston Celtics.

The Cavaliers moved to 9-5 with their sixth win in seven games on Saturday, making this their best start to a season since 2016-17 – a year in which LeBron James led the team to the third of four straight NBA Finals visits.

This latest 91-89 triumph was particularly impressive as Cleveland trailed by 19 points when Mobley returned to the game late in the third quarter.

"We keep talking about chemistry and bonding and belief in one another, and that was on full display tonight," said Bickerstaff. "That's the only way you can explain it.

"There's no basketball reason we should have won that game, but there was a collective spirit that refused to allow us to lose that game. That's what we keep talking about brewing in that locker room.

"Don't get me wrong, some guys made critical plays and carried their weight, but it's the spirit of that basketball team, that has that fight in them, that won't give up."

Several of those critical plays belonged to third overall pick Mobley, who finished with 19 points, nine rebounds, three blocks and two steals in 40 minutes. Of those, 12 points, two blocks and a steal came in the fourth quarter as he played its entirety.

No player in the NBA scored more clutch points than Mobley's six on Saturday, albeit tied with the Celtics' Jayson Tatum – who the Cavs man was asked to stop.

"It's the will to win basketball games," Bickerstaff said of Mobley's best trait. "Literally the only thing that matters to him is: how do I help this team win?

"Not only was it the block, but it's the free throws, it's the baseline jumper, it's the post move to get to the finish. It was an array of different things.

"Then at the end of the game, we had him on Jayson Tatum. We put him on the other team's best player. Whatever it takes to win, he's willing to do it.

"He's not satisfied with these small victories or these small moments. He understands what he wants long-term, and he understands that in order to get there, you've got to do it every night.

"He didn't start out blazing, he was working his way through it in the first half. Then as the game got going, he found his way. And when it was clutch time, he stepped up big."

Mobley has quickly proven a threat from anywhere on the court in his short time in the NBA but is especially effective at the rim, making 70.1 per cent of his attempts.

In fact, 36.8 per cent of his successful field goal attempts have been dunks, with his 32 made dunks ranking joint-third in the NBA. Team-mate Jarrett Allen's 47 lead the way, while no team can rival the Cavaliers' combined 98.

Allen's latest dunk put Cleveland up with 35.9 seconds left against Boston, and Darius Garland said: "It's super fun, just bringing all the crowd into it, the arena gets pumped up. I like seeing it a lot."

Bickerstaff, whose team rank fourth in the league for points in the paint (672), added: "We want to put pressure on the rim, and however we can do that, we'll take it.

"Jarrett is an elite lob threat, and when you put that much pressure on the rim, defenses get concerned. Even if it's only two points, it's an emphatic two points, and defenses don't like that. Then they start to collapse and we've got wide open threes.

"We've got guys who we feel like can dominate the paint – that's our objective: offensively, we want to dominate the paint as much as we can."
