Los Angeles Lakers coach Frank Vogel is prioritising offensive work after seeing his side suffer a third successive defeat in the absence of LeBron James and Anthony Davis.

James suffered an ankle sprain last week, the issue forcing him to join Davis on the injury list, with the latter struggling due to a calf strain and Achilles tendinosis.

While James is only a recent absentee, Davis has already missed a considerable chunk of the season, with the Lakers 7-10 without him.

Center Davis is not expected back for at least another three weeks and there is growing concern James may yet need a similar amount of rest to avoid aggravating the problem.

The Lakers' latest setback came at the hands of the New Orleans Pelicans in a 128-111 loss, meaning they have dropped to fourth in the Western Conference, and Vogel knows where he will be focusing much of his attention.

"We have a lot of emphasis on offensive side in last few days with LeBron and AD [Davis] out," he said. "I thought we had some growth, some real growth, some real positives about what we're doing offensively.

"We had a stretch in the second quarter where we hit a big drop that really hurt us in this game, but with the emphasis on the offensive end we didn't play well enough.

"We're going to miss guys like that, LeBron and AD, on both sides of the ball. So getting us organised offensively is probably by top priority right now.

"I know we can tighten up defensively but we've got to be better on that end."

Nevertheless, Vogel is also adamant he has enough quality at his disposal without James and Davis to steer the defending NBA champions back on track.

"We are staying positive, we have great belief in this group," he continued. "Even with Lebron and AD out, we can win games in this stretch and there's going to be a silver lining at the end of it.

"The growth we exhibit while shorthanded will pay dividends down the stretch. We're going to remain positive, keep playing super hard like today.

"We've just got to execute better and collect as many wins along the way as we can."

The Brooklyn Nets and Philadelphia 76ers continue to go toe-to-toe in the Eastern Conference after both championship hopefuls won in the NBA on Tuesday.

James Harden led the way with a double-double as the star-studded Nets topped the Portland Trail Blazers 116-112.

In the absence of fellow superstars Kyrie Irving (personal matter) and Kevin Durant (hamstring), Harden posted 25 points and a career high-tying 17 assists to fuel the short-handed Nets in Portland.

Jeff Green finished with 20 points – 15 in the first half – Nicolas Claxton put up 16 of his own, while Blake Griffin had eight points, five rebounds and two steals in his second Nets appearance.

Enes Kanter scored 19 points and collected 19 rebounds for the Trail Blazers, who also had 22 points from All-Star Damian Lillard.

The Nets (30-14) remain within a game of the Eastern Conference-leading 76ers (31-13) after they held on to beat the Golden State Warriors 108-98.

Behind Tobias Harris' 25 points and 13 rebounds and Ben Simmons' 22 points, the 76ers earned their fifth consecutive road victory – the team's longest winning streak away from home since winning seven straight in 2018.

The Warriors – without star Stephen Curry (back) – threatened to complete a stunning comeback, having been outscored 35-17 at the end of the opening quarter, while they trailed by more than 20 points before half-time.

Zion makes history

Zion Williamson helped the New Orleans Pelicans top the slumping Los Angeles Lakers 128-111. The 20-year-old's 27 points and nine rebounds saw him become the first NBA player younger than 21 to score at least 20 points in 21 consecutive games. Pelicans team-mate Brandon Ingram posted a season-high 36 points.

MVP candidate Nikola Jokic had his 12th triple-double of the season as the Denver Nuggets beat the Orlando Magic 110-99. Jokic posted 28 points, 15 rebounds and 10 assists for a franchise-best 53rd career triple-double. Only Washington's Russell Westbrook (14) has more triple-doubles this season.

It is almost impossible to replace Joel Embiid, but Tony Bradley stepped up in a big way for the 76ers. The 23-year-old was flawless against the Warriors, going eight-of-eight for 18 points and 11 rebounds. Bradley became the first 76ers player not to miss a shot in a game on a minimum eight attempts since Dikembe Mutombo in 2002.

All-Star Julius Randle finished with 37 points to lead the New York Knicks past the lowly Washington Wizards 131-113.

Lakers feeling absence of star duo

The Lakers – who came out of the All-Star break on a 4-0 run – are now 0-3 since LeBron James suffered an ankle injury, with fellow star Anthony Davis (calf) also sidelined.

Tyler Herro headlined the Miami Heat's woes after last season's NBA Finals participants lost 110-100 at home to the Phoenix Suns. Herro was three-of-11 from the field, while he was just one-of-six from three-point range for seven points in 26 minutes.

Robinson throws it down!

New York's Mitchell Robinson got up high for a powerful dunk in the second quarter against the Wizards.

Nets at Jazz

It is back-to-back outings for the high-flying Nets (30-14), who travel to the NBA-leading Utah Jazz (31-11) on Wednesday.

Brooklyn Nets star Kevin Durant remains sidelined until at least Friday as the former MVP is at a "critical" point in his recovery from a hamstring injury, according to Steve Nash.

Durant has been sidelined since February 13 due to a hamstring strain, which forced him to sit out the NBA All-Star Game this month.

The star-studded Nets are second in the Eastern Conference and as they eye a run to the NBA Finals, first-year head coach Nash is not prepared to rush Durant back from injury.

"We just felt like it didn't benefit him to travel across the country while he is trying to get that critical last part of his rehab done," Nash said as Durant sat out Tuesday's 116-112 win over the Portland Trail Blazers – the first of a three-game road trip.

The Nets will face the NBA-leading Utah Jazz and Detroit Pistons before returning home to Brooklyn to host the Minnesota Timberwolves on Monday.

"Just trying to make sure that functional strength is there and that he's — we're confident that he can re-enter playing safely. That is the thing, right? Kevin is doing very well," Nash said.

"If this was the playoffs, there's a chance he'd be back, you know, very soon. But there's no point in taking a big risk with him when the most important thing is to get him back for the remainder of the season."

Nash added: "He is working out on the court pretty much every day, he looks great."

Durant is averaging 29.0 points, 7.3 rebounds and 5.3 assists per game for the Nets this season.

San Diego Padres star Fernando Tatis Jr. is listed as day to day heading into Opening Day after exiting Tuesday's Spring Training matchup with left shoulder discomfort.

Tatis – who signed a record-setting extension with the Padres last month – an eye-popping 14-year, $340million contract – left San Diego's 5-4 win over the Cincinnati Reds in the third inning after making a play at shortstop.

The Silver Slugger will be re-evaluated on Wednesday as the Padres prepare to open their 2021 MLB season against the Arizona Diamondbacks on April 1.

"Talking to Fernando, he didn't think it was that bad," Padres manager Jayce Tingler said post-game.

"He's like: 'In season, I would probably go'. Obviously we're going to be precautious."

Tingler added: "We're going to be just day to day going forward with it.

"Hopefully he comes in tomorrow and it's feeling pretty good. We'll just have to wait and see."

Tatis won a Silver Slugger award last season, having hit .277 with 17 home runs and 45 RBIs in the coronavirus-shortened 2020 campaign.

The powerful 22-year-old is the first player in MLB history to have at least 35 home runs and 25 stolen bases within the first 150 games of his career.

Tatis packs a punch with the bat – he led the majors in average exit velocity (95.9 mph), hard hit percentage (62.2), and balls hit 95-plus MPH (102).

He also enjoyed a remarkable rise defensively following an erratic rookie season at shortstop.

Tatis went from minus-13 outs above average (OAA) to plus-seven – his plus-20 improvement the largest of any player across that period.

When it comes to on-base plus slugging, Tatis stacks up well. Since 1920, Tatis (150.8) is only behind Juan Soto (153.9 – 2018-20), Albert Pujols (159.3 – 2001), Jimmie Foxx (160.0 – 1925-29), Ted Williams (161.5 – 1939-40) and Mike Trout (165.0 – 2011-13) for highest OPS-plus up until the age of 21.

Using the same timeframe, but for wins above replacement (WAR) among shortstops, Tatis (5.6) ranks ninth. Alex Rodriguez is top (13.6 – 1994-97).

Golden State Warriors star Stephen Curry will be sidelined for at least another week after an MRI showed inflammation in his tailbone.

Curry has not played since suffering a bruised tailbone in the Warriors' win over the Houston Rockets last week.

The former two-time MVP was already ruled out of his third consecutive game – Tuesday's NBA showdown with the Eastern Conference-leading Philadelphia 76ers.

But Curry will miss at least four more games, Warriors head coach Steve Kerr revealed prior to the 76ers clash.

"We're going to re-evaluate in a week," Kerr told reporters. "He got an MRI this morning and it showed inflammation in that tailbone.

"He had made some progress the first couple of days just resting and then he did a little bit more work [Monday] and was still pretty sore.

"So our training staff and Steph put their heads together and decided this is going to be a little bit longer than we thought and hoped. So we'll re-evaluate in a week."

Curry is averaging 29.0 points (fifth best in the NBA), 6.2 assists and 5.3 rebounds per game for the Warriors this season.

The three-time NBA champion has made the most three-pointers in the league in 2020-21 (182), while his three-point average of 4.7 is the best in the NBA.

Brooklyn Nets star James Harden has been cleared to face the Portland Trail Blazers in the NBA.

Harden was listed as questionable for Tuesday's matchup against the Trail Blazers in Portland due to neck soreness.

Former MVP Harden appeared to hurt his neck during a collision with Garrison Mathews in Sunday's 113-106 win over the Washington Wizards.

But Harden will take to the court away to the Trail Blazers, while fellow stars Kyrie Irving (personal matter) and Kevin Durant (hamstring) are sidelined.

Harden was on the court for 39 minutes against the Wizards, the most for any Nets player. Prior to Sunday's victory, the former Houston Rockets star had featured for 40-plus minutes in four of the franchise's previous eights outings either side of the All-Star break. 

This season, Harden is averaging the most minutes in the NBA with 37.9, with Julius Randle of the New York Knicks next on 37.

Harden is averaging 25.3 points, a league-best 11.1 assists and 8.0 rebounds per game for the star-studded Nets this season.

He tops the list for most assists in the league in 2020-21 (410), while he ranks fifth for points/assists/rebounds averaged per game (44.4).

The Toronto Blue Jays' prized recruit George Springer is "extremely motivated" to be ready for Opening Day after being diagnosed with an oblique strain.

Toronto lured 2017 MLB World Series champion and MVP Springer to Canada on a six-year, $150million contract via free agency – the largest deal in franchise history.

But Springer's preparations for the April 1 MLB opener against American League (AL) East rivals the New York Yankees have been interrupted by a strained oblique muscle.

Former Houston Astros star Springer, though, is not expected to miss a lot of action for the entertaining Blue Jays.

"The MRI revealed an injury that he is able to play baseball with," Blue Jays general manager Ross Atkins said on Tuesday.

"He is extremely motivated and driven to be ready for Opening Day."

Springer leads MLB with 136 home runs from the lead-off spot since 2015. The Blue Jays as a team have 129 homers from the lead-off spot over that time, per Stats Perform.

A two-time Silver Slugger, Springer has 39 lead-off home runs in his career – fourth most all-time behind Rickey Henderson (73), Ian Kinsler (48) and Brady Anderson (44).

Springer has recorded seven career World Series home runs – most from the lead-off spot all-time – and he is 19-for-56 (.339) in the World Series in his career. No other current Blue Jays player has a World Series hit in their career.

The three-time All-Star's 174 home runs since debuting in MLB via Houston are third most by an Astro in a player's first seven career seasons, behind only Jeff Bagwell (187) and Lance Berkman (180).

Meanwhile, Atkins said reliever Kirby Yates is expected to have season-ending surgery on his right elbow.

An All-Star in 2019, Yates only joined the Blue Jays from the San Diego Padres this offseason.

Charlotte Hornets star LaMelo Ball underwent surgery to address a fracture in his right wrist, the NBA franchise announced on Tuesday.

The Hornets said the surgery was successful for Rookie of the Year favourite Ball, who will have his wrist immobilised before being re-evaluated in four weeks.

Ball is reportedly set to miss the remainder of his first season in the league after hurting his wrist in Saturday's 125-98 loss to the Los Angeles Clippers.

The 19-year-old has taken the NBA by storm since being drafted by the Hornets with the third pick last year.

Ball has been averaging 15.9 points, 5.9 rebounds, 6.1 assists and 1.59 steals (seventh in the NBA) per game this season.

Among rookie leaders, Ball ranks first in assists and steals, second in scoring and is tied for second in rebounds.

Ball is the only player over the last 60 years to lead all rookies in total points, rebounds, assists and steals at the All-Star Break.

Last month, Ball joined Stephen Curry (2010) and Jason Kidd (1995) as the only rookies with seven-plus threes and 10-plus assists in a game and is the youngest to do so.

Ball also became the youngest player in NBA history to record a triple-double in January.

Three-time champion Venus Williams was dumped out of the Miami Open on Monday in straight sets by Kazakhstan's Zarina Diyas. 

Diyas, ranked 89th in the world, had lost her only previous match against seven-time major winner Williams, but saw off the American 6-2 7-6 (12-10).

"I'm very happy with the win, it was very tough," Diyas said after her victory. "Venus, I looked up to her when I was little, she's such a legend. So for me, it's a really special win."

Elsewhere, Shelby Rogers overcame fellow American Madison Brengle 6-3 6-3 to set up a second-round clash with fifth seed Elina Svitolina.

"I'm really happy to get through that one, she's a really tricky player," Rogers said. "It's actually my first win at this site. The last time I was here, I was spectating, as an injured person! So I'm very happy to be here."

There were also wins for Magda Linette, Sorana Cirstea, Barbora Krejcikova and Kaia Kanepi, while Ajla Tomljanovic beat Anastasia Potapova to seal a clash against second seed Naomi Osaka in the next round.

The British and Irish Lions' tour of South Africa is set to go ahead as planned later this year after proposals to stage matches elsewhere were rejected.

Due to continued complications surrounding the coronavirus crisis, questions were raised over whether the Lions would be able to travel to South Africa for the eight-match trip.

But rather than host matches in the UK and Ireland, or take up Australia's offer to play games Down Under, it has been decided to press ahead with the original itinerary

The Lions and SA Rugby released a joint statement on Tuesday to confirm an agreement is in place over the staging of the tour, which begins on July 3 and continues into early August.

"After reviewing information relating to the various contingency scenarios being considered, I can confirm that the board's intended position is for the Tour to go ahead as scheduled in South Africa in 2021," said Lions chairman Jason Leonard.

"We acknowledge that there is a significant amount of work still to be undertaken to deliver a robust Covid-19 countermeasure plan to ensure a successful, safe and uninterrupted Tour. SA Rugby will have our full support to help implement this plan."

However, the original plan for the Lions to play five warm-up matches against provincial teams, an invitational side and second-string South Africa A before the three-Test series with the Springboks could still change.

"We appreciate the Lions' faith and share their desire to see a safe and successful tour,” said SA Rugby president Mark Alexander in the same statement. 

"We have been in regular contact with our government to make that a reality against the backdrop of the pandemic and its predicted progression over the coming months.

"There are serious financial implications for SA Rugby, should the event take place without any supporters in attendance, and we cannot ignore that in our considerations. 

"But we are determined that the eventual outcome will deliver the best occasion and experience for players, supporters and our commercial partners."

Speaking earlier on Tuesday, RFU chief executive Bill Sweeney acknowledged the preferred contingency plan of staging the tour in the UK had become increasingly unviable.

"It was always the preferred option to go to South Africa," he said. "We had to develop a whole range of different scenarios given the potential outcomes and one of those was a UK series.

"It's quite controversial as it's not the spirit of the Lions, but as fall-back option, we thought it was a strong one. If they can't host it, the agreement's off and we've probably run out of time to host it in the UK, so you play in 2025."

Lions coach Warren Gatland is due to announce a squad for the tour at the start of May, with the first warm-up match to be played on home soil on Murrayfield against Japan on June 26.

Andy Murray will not feature at the Miami Open after withdrawing from the tournament because of a groin injury.

The former world number one and three-time grand slam champion has featured only twice on the ATP Tour this season, losing in the first round in Montpellier before going one better in Rotterdam, where he was beaten by Andrey Rublev.

He withdrew from this month's Dubai Tennis Championships to be with his wife as she gave birth to their fourth child.

And his return to action has been delayed again, with Murray missing out on a tournament he has won twice.

The 33-year-old beat Novak Djokovic in the 2009 final and defeated David Ferrer to lift the trophy four years later. He lost to Djokovic in the final in 2012 and 2015.

Murray holds a 28-9 record in Miami, where he had been given a wild card. His place in the draw will be filled by a qualifier or a lucky loser.

The Scot has not competed in a Masters 1000 event since 2016, the next event at that level on the calendar is next month's Monte Carlo Masters.

England will conduct a "brutally honest" internal review of their Six Nations performance but will not rush the decision on the future of Eddie Jones.

The 2019 World Cup finalists finished fifth in this year's Six Nations tournament, losing all three games against Scotland, Wales and Ireland for the first time since 1976.

A spirited victory over France had restored some credibility to the side after a shock 11-6 home defeat to Scotland and a resounding 40-24 loss in Cardiff, but their campaign concluded last weekend with a 32-18 reverse in Dublin.

England conceded 121 points in their five games, more than in any previous Five or Six Nations championship, leaving Jones' position as head coach under serious scrutiny.

Bill Sweeney, CEO of the Rugby Football Union (RFU), accepted there was huge disappointment around their performance and that tough questions must be asked as they attempt to build a squad capable of winning the World Cup in two years' time.

However, he insisted on Tuesday that any possible changes to the team will be given great consideration.

Asked to summarise England's Six Nations campaign, Sweeney replied: "How long have you got?

"It's a tough question. We're all incredibly disappointed. England don't go into a Six Nations to come fifth, which is why we'll have a thorough debrief.

"We had a debrief scheduled for May and we'll probably bring it forward to April. It needs to be a thorough, brutally honest analysis of what went wrong and why.

"Since Japan, our focus is on going and winning a World Cup in France.

"You'd expect us to do an absolute and full debrief. You have to recognise and respect Eddie's achievements since he's been here: three Six Nations championships, a grand slam, a World Cup final - that's a tremendous performance.

"But he wants to understand this as much as anybody and we want to let him talk to us about what happened in the Six Nations and are we on track to where we want to get to in 2023.

"It's really important at this stage to apply good old English calm. We have to react, we won't do nothing, but it's important not to overreact. We won't leave any stone unturned in trying to understand it.

"It's a young squad, it was the youngest ever team in a World Cup final, and yet we're in a period of transition. It's unusual. When you're in transition, you want to make sure you're heading in the right direction.

"I don't think I can honestly answer [if he will be sacked]. He's as disappointed as we are, and we'll do this debriefing session together."

Houston Rockets coach Stephen Silas was like a new man after his team finally ended a 20-match losing streak in the NBA.

Silas was left distraught after Sunday's narrow 114-112 loss to the Oklahoma City Thunder, but felt a huge weight lifted off his shoulders following a long-awaited victory over the Toronto Raptors the next day.

Houston were in the midst of a franchise-record drought – the Rockets' skid tied for the ninth-worst in NBA history and the longest since the Philadelphia 76ers' 28-game losing streak across the 2014-15 and 2015-16 campaigns.

But the Rockets recorded an overdue victory on Monday, celebrating their first win since February 4 behind John Wall's 19 points, 11 rebounds and 10 assists in a 117-99 triumph over the Toronto Raptors.

"It's like indescribable for a win in March of this crazy season," Silas said.

"I'm just so proud of the guys. When you're like going through it and fighting so hard and you just see the disappointment in the players' faces after loss after loss after loss.

"Then to go into the locker room after today's game and everybody's just happy and joyous, I mean, it's super cool and great.

"I was down and out yesterday. It seems like a week ago now. We regroup, we come together, and it feels a lot better just because I know it feels great for the players.

"Like, whatever for me, but I'm just so happy for those guys that they don't have to hear about it and deal with it."

The game saw Wall's first triple-double since March 2016 as the Raptors crashed to a ninth consecutive defeat – now the league's longest active losing run.

And Wall conceded it had been a tough spell to endure, one he was glad to see come to an end.

"Losing 20 straight, we haven't been healthy, but that's not an excuse because everybody's been going through health and safety protocols and injuries," he said. 

"We just went out there and competed, no matter what and what was going on."
