These are uncertain times for the NBA as it continues to navigate the coronavirus pandemic.

COVID-19 protocols have left rosters lighter in number and, with contract tracing having a major impact, it is far from surprising to see games being postponed.

The absences have offered some players greater opportunities to impress in the embryonic stages of a shortened season that will require adaptability from all involved.

After an eventful week, Stats Perform assesses those performers who have stood out - for good and bad reasons - in games from January 4-10.

RUNNING HOT...

Bradley Beal 

It has been a tough start for the Wizards, who are stuck in the basement of the Eastern Conference. Beal, however, has excelled amid the defeats. He is averaging 35 points per game for the season but has been particularly spectacular in recent outings, including dropping 60 against the Philadelphia 76ers. While it set a new career best for points - and tied a franchise record too - Beal made clear he is not interested in personal milestones: "I just want to win. Sometimes you might be able to score 40, 50, 60, whatever the case may be, but I just want to win".

Tyrese Maxey 

The 21st pick in the 2020 draft had scored a combined tally of 52 points through his first nine NBA appearances. Then, amid injuries, positive COVID tests and coronavirus-enforced isolations, Maxey was thrust into a leading role as one of just seven players available against the Denver Nuggets on Saturday. His response to the situation was to score 39 points in just under 44 minutes of action, having taken 33 shots but no free throw attempts. In doing so, he became the first 76ers rookie with at least 35 points in a game since franchise legend Allen Iverson in 1997. 

Jimmy Butler 

Butler has begun to heat up after a cold start to the new campaign for Miami. The five-time All-Star had been hampered by injury issues but has looked back to somewhere near his best of late, managing 18, 26 and 26 points in his past three games. Surprisingly, though, Butler is still yet to manage a successful three-point attempt, missing on his seven shots from deep so far. It is a different story from the free-throw line, though, going 28 of 29 from the charity stripe.

LaMelo Ball 

The rise and rise of the youngest Ball brother continues. The point guard became the youngest player in NBA history to score a triple-double as Charlotte Hornets beat the Atlanta Hawks on Sunday. At 19 years and 140 days old, Ball had 22 points, 12 rebounds and 11 assists. He had narrowly missed out on achieving the feat in his team's previous outing, against a New Orleans Pelicans team that included older sibling Lonzo. His rebounding average has gone from 4.33 a game to 9.25 across the past week. 

GOING COLD...

James Harden  

The NBA's scoring champion for the previous three seasons, Harden is still averaging 26 points per game despite continued doubts over his long-term future in Houston. However, it has not been a particularly productive week for the guard, who has not reached double digits in terms of field goals made in four straight outings. There were 15-point displays against both the Pacers and the Magic, then 20 points in a defeat to the Lakers. Across that stretch, Harden was six for 22 from three-point range. Astonishingly, he did not attempt a solitary free throw against Orlando. 

Trae Young 

To say Young has gone cold from deep recently is an understatement. The Atlanta Hawk landed five of six attempts in the season-opener against the Bulls, but since then has managed just nine successful long-range shots, including going a combined one for 14 in his most recent three appearances. Understandably, then, his average for points per game has dipped from 28.17 on January 3 to 17.67 for the past week.

Russell Westbrook 

A quadriceps injury will keep Westbrook sidelined for at least a week. His early form with the Wizards has been steady, including reaching double digits for points in all of his seven games for the franchise. Where there has been a dip for the former NBA MVP is in rebounding. He was up at 11.20 per game for the season by January 3, but he has averaged 6.00 for the past week following reduced contributions in defeats to the 76ers and the Celtics.

Blake Griffin  

Griffin hit with eight of 16 three-point shots for Detroit against the Cavaliers on December 26, but his output from long range since suggests that number could prove to be a post-Christmas outlier when compared to the rest of the season. In the past week, the 31-year-old has landed two from deep out of 18 tries for the struggling Pistons. His overall field goal percentage is down on his career mark too (37.6 per cent from 49.7 per cent), explaining why he is averaging 13.9 points per game. 

The Philadelphia Eagles have fired head coach Doug Pederson, according to reports.

Pederson had been said to be meeting with owner Jeffrey Lurie to outline his plans for the future, with his position thought to hinge on that discussion.

It seems he failed to convince Lurie and the franchise hierarchy to keep him in the post, with NFL Media's Tom Pelissero first reporting his firing.

Pederson, who took over in 2016, led the Eagles to their first Super Bowl title in his second season at the helm.

Philadelphia's first Lombardi Trophy came at the end of a storied playoff run, in which unheralded backup Nick Foles led them to glory after then-MVP candidate Carson Wentz suffered a serious knee injury.

The Eagles overcame the New England Patriots 41-33 in Super Bowl LII but Wentz's struggles to recapture his 2017 form following his comeback from injury played a significant role in Philadelphia's failure to scale the same heights in Pederson's subsequent three seasons.

Pederson oversaw playoff campaigns in 2018 and 2019, the latter despite a roster decimated by injury.

However, he attracted increased criticism amid a dismal 2020 season that saw a sharp decline from Wentz, who was eventually benched and forced to watch the final few weeks of a 4-11-1 year from the sideline.

His replacement, rookie quarterback Jalen Hurts, was one of the few bright spots for Philadelphia. The controversial in-game benching of Hurts in favour of Nate Sudfeld for the Week 17 loss to the Washington Football Team saw Pederson placed under further scrutiny as he faced accusations of overt tanking for draft position.

Pederson had claimed he made the move to evaluate Sudfeld, but the future at quarterback in Philadelphia is now a matter for his successor and general manager Howie Roseman.

In five seasons with the Eagles, Pederson compiled a 42-37-1 record in the regular season. He went 4-2 in the playoffs.

Manchester United will host bitter rivals and Premier League champions Liverpool in the fourth round of the FA Cup.

The European Champions Cup and Challenge Cup have been temporarily suspended after the French authorities ruled the participation of Top 14 clubs to be too much of a public health risk. 

European Professional Club Rugby (EPCR) made the announcement on Monday following a meeting last week with French government officials. 

Due to concern over a new variant of coronavirus, the French government has decided to prevent its clubs from participating in games both in France and in the United Kingdom and Ireland. 

It means the EPCR has been forced to suspend the Champions Cup with two rounds of the pool phase remaining. The Challenge Cup is in its preliminary phase. 

The development would appear to place the 2021 Six Nations, scheduled to start with a meeting between France and Italy in Rome on February 6, in jeopardy. 

Last year's Six Nations tournament was only completed in October because of the pandemic-enforced delay. 

An EPCR statement read: "EPCR and the Ligue Nationale de Rugby took part in a meeting by audio conference last week with representatives of the French ministries of the Interior, Health and Sport, as well as of the President's office. 

"Notable updates to EPCR's COVID-19 protocols were presented to the French authorities, including the addition of PCR tests no earlier than three days before matches in the tournaments, conforming to French government guidelines and supplementing the existing, meticulous contact tracing measures put in place with a view to limiting the risk of transmission. 

"Against the backdrop of the recent detection of a new strain of coronavirus, the French government has directed that French clubs postpone their participation in EPCR's tournaments for the month of January, both for matches scheduled in France and for those due to be played in the United Kingdom and Ireland. 

"On the basis of this directive, EPCR had no choice but to temporarily suspend the pool stage of the Heineken Champions Cup and the preliminary stage of the Challenge Cup. 

"While respecting all further directives by governments and local authorities, and prioritising the health and welfare of players and club staff, EPCR, in conjunction with its shareholder leagues and unions, remains committed to trying to find a solution which will enable it to resume and complete the tournaments as soon as practicable. 

"EPCR will be making no further comment at the present time." 

Leo Duarte has joined Istanbul Basaksehir on an initial 18-month loan deal from Milan.

The Super Lig side have the option to buy the 24-year-old permanently at the end of his loan deal on June 30, 2022. 

Centre-back Duarte joined Milan in August 2019 in a reported €11million deal from Flamengo. 

He made six appearances for the club last season – all in Serie A – and has appeared only three times this term across the Italian top flight and the Europa League. 

A Milan statement read: "The club would like to thank Leo for his professionalism and wishes him the best for his personal and professional future."

The top two seeds are both out at the Abu Dhabi Women's Tennis Open after Sofia Kenin and Elina Svitolina suffered quarter-final defeats on Monday.  

Kenin had won the two previous meetings against Maria Sakkari and appeared on course to retain her 100 per cent record when cruising through the opening set.  

However, Sakkari hit back to stun the top seed, dropping just two more games as she rallied in emphatic fashion to triumph 2-6 6-2 6-0 after one hour and 23 minutes on court.  

"I think I did way too many errors and I was hitting too big when I didn't have to. But I'm glad that once again I found the way to turn the match around," the ninth seed told reporters.

Next up for Sakkari will be Aryna Sabalenka, who extended her impressive winning run to 13 matches after coming through a three-set tussle with Elena Rybakina.  

The fourth seed has not lost since going out at the 2020 French Open to Ons Jabeur - a result she avenged when the pair met on Sunday in the last eight in Abu Dhabi.  

In the other half of the draw, Veronika Kudermetova once again got the better of Svitolina, ending the second seed’s hopes of success in the tournament. 

Russian Kudermetova – who won their only previous meeting on the WTA Tour – came out on top in the deciding tie-break to triumph 5-7 6-3 7-6 (7-3).  

She will take on another player from Ukraine next, Marta Kostyuk overcoming a nightmare opening set to beat Spaniard Sara Sorribes Tormo 0-6 6-1 6-4 and reach the last four.

Paulo Dybala could be out for almost three weeks after suffering a knee injury against Sassuolo on Sunday, Juventus have confirmed.

The Argentina international was replaced by Dejan Kulusevski in the 43rd minute of Juve's 3-1 Serie A win at the Allianz Stadium.

The club confirmed on Monday he has suffered a "low-grade lesion of the medial collateral ligament" in his left knee and will be out of action for "approximately 15-20 days".

The 27-year-old looks certain to miss the Coppa Italia clash with Genoa on Wednesday, the Supercoppa Italiana against Napoli next week and Serie A games versus Inter and Bologna. He could also miss another league game against Sampdoria on January 30.

Juve's only Serie A defeat this season came when Dybala was not in the side. Their win ratio without him is 40 per cent compared to 63.6 per when he features.

When going back to the start of the 2019-20 campaign, Juve have lost as many times in the 10 league games without Dybala (four) as they have in the 44 in which he has taken part – their win percentage sliding from 72.7 to 30 in his absence.

Juve also confirmed Weston McKennie and Federico Chiesa underwent tests on Monday, which revealed neither player is suffering from a serious injury.

Fair or foul? Gamesmanship or unsportsmanlike conduct? Steve Smith found himself in the spotlight after his actions on the final day of the third Test between Australia and India in Sydney.

Smith was at his best with the bat in the match, making scores of 131 and 81 as he returned to form in style after a recent lean spell.

However, it may well be his footwork during Monday's final day will overshadow what he achieved during the rest of the Test.

With India battling to save the game, stump camera footage seen on social media showed Smith standing at the crease during a break in proceedings, the Australian shaping up as if he was batting, including marking a guard.

His actions at the crease forced India's Rishabh Pant to retake his own guard before play resumed, with the moment becoming a hot topic on Twitter.

"Tried all tricks including Steve Smith trying to remove Pant's batting guard marks from the crease," former India batsman Virender Sehwag wrote to accompany the footage that was seen on the international feed of the broadcast.

Retweeting Sehwag's post, ex-England captain Michael Vaughan added: "This is very very poor from Steve Smith!!". Meanwhile, David Lloyd, who played and coached England before becoming a television commentator, wrote: "How childish".

Pant did not seem too perturbed by what happened, however, going on to make 97 as India impressively secured a draw.

Smith was sacked as Australia captain following the ball-tampering scandal during the tour of South Africa in 2018. Along with team-mate David Warner, he was banned for 12 months from international and domestic cricket for his involvement in the incident.

Cameron Bancroft, who was the player caught by television cameras appearing to use sandpaper to alter the condition of the ball during the third Test against the Proteas at Newlands, was handed a nine-month suspension.

Tim Paine, who took over as skipper of the Test side, was also trending on social media after a verbal exchange with India's Ravichandran Ashwin during the final session of play at the SCG.

Ashwin pulled away before a delivery as he and Paine shared words, their conversation picked up by the stump microphone.

England paceman Stuart Broad pointed out on Twitter that such situations are "part of the game" during a Test match, though did suggest Paine's use of an expletive could land him in trouble.

The wicketkeeper was indeed fined after the game, though lost 15 per cent of his match fee as punishment for dissent after questioning an umpiring decision during day three of the match.

Ashwin ended up unbeaten on 39 to help India survive and remain level at 1-1 in the series ahead of the final game in Brisbane.

Neymar resumed Paris Saint-Germain training on Monday in a boost to their preparations for a Trophee des Champions clash with Marseille.

The Brazil star has not yet featured under Mauricio Pochettino, having sustained an ankle injury in December.

According to Le Parisien, the former Barcelona forward is "50-50" to face Marseille in Wednesday's game in Lens.

Neymar has only managed seven Ligue 1 appearances this season, scoring three times and providing three assists.

His most telling performances have been in the Champions League, where six goals in five games helped PSG to win a tough Group H ahead of RB Leipzig and Manchester United.

Leandro Paredes, Danilo Pereira and Presnel Kimpembe, who suffered a hamstring injury last month, also returned to training in Monday's session.

Pochettino, who took over following Thomas Tuchel's sacking in December, is bidding to win his first trophy as a coach this week.

He recorded his first win as PSG boss on Saturday, when Moise Kean, Mauro Icardi and Pablo Sarabia scored in a 3-0 Ligue 1 victory over Brest.
