Floyd Mayweather collected a routine victory in his exhibition boxing match against YouTube star Deji Olatunji on Sunday.

Mayweather, who is considered one of the greatest boxers to ever live, was never threatened, slowly building his pace in the eight-round fight.

He finished the job in the sixth round with an extended flurry, allowing the referee to step in and call it off for a TKO victory.

It is Mayweather's third exhibition since May as he continues to accept fights from non-professional boxers, having last fought professionally against Conor McGregor back in 2017, while his last win against a boxer was in 2015.

Speaking in the ring to DAZN after the result, Mayweather pointed to some swelling under his own eye as an indication that the crowd got their money's worth.

"I'm glad that he landed a good shot, this is part of fighting, this is a part of entertainment," he said. "These people want to see entertainment, and fun, and that's what we both gave them tonight."

He finished with some encouraging words to his opponent, saying "you're a hell of a fighter, a hell of a competitor, keep up the great work, and keep building".

Taylor Fritz stunned Rafael Nadal on his ATP Finals debut on Sunday, producing a powerful display to beat the 22-time grand slam winner 7-6 (7-3) 6-1 in the duo's group-stage opener.

The American put Nadal under pressure from the off in Turin, failing to give up a single break point as he dominated on his own serve to take the 36-year-old to a tie-break in the opening set.

Nadal allowed Fritz to seize the initiative with a double fault at the start of that tie-break, and the American grasped his opportunity by clinching the first set with a big forehand winner.

The top seed's struggles continued into the second set as Fritz, moving well and dictating proceedings from the baseline, claimed the match's first break four games in before going 5-1 up by repeating the trick in a back-and-forth sixth game.

Fritz then wrapped up the win with another dominant display of serving, clinching his second victory over Nadal and denting the Spaniard's bid to win a title that has eluded him throughout his illustrious career.

Having been beaten by Tommy Paul at the Paris Masters and Frances Tiafoe at the US Open, Nadal has now suffered three consecutive defeats, and he must bounce back when he faces Felix Auger-Aliassime on Tuesday.

Kyrie Irving remains suspended by the Brooklyn Nets for his sharing of problematic material on Twitter, and he took to the social media platform again on Sunday in an attempt to explain himself.

Irving, 30, played a career-low 29 games last season as he took a stand against New York's vaccine mandate, and he has a list of tasks to complete before he can return to the floor for this campaign.

The former champion with the 2016 Cleveland Cavaliers is facing intense backlash after sharing a film containing anti-semitic conspiracies, and when initially asked to apologise, he refused, instead choosing to dance around the subject without taking accountability.

Irving eventually did issue an apology after his suspension was announced, and he vaguely tweeted again on Sunday in defense of his character.

"I was not put here on earth to participate in any religious/political wars or incite racial disharmony/prejudice within communities," he wrote.

"We are all equal under the sun and I am here to participate in the building of an Equal world and follow the Word from the Most High/GOD/YAH."

Irving has met with league commissioner Adam Silver, who is Jewish, and still has to meet with Jewish leaders in order to fulfil the requirements set before he can begin the process of returning to play.

Josh Allen threw an overtime interception as the Justin Jefferson-inspired Minnesota Vikings fought back to prevail 33-30 in the game of the NFL season so far.

Minnesota looked set to fall short in the biggest test of their credentials as contenders to date when Greg Joseph missed an extra point after a C.J. Ham touchdown to leave the Vikings trailing 27-23 in the fourth quarter.

Yet an already engrossing contest to that point served as merely a prelude to an inexplicable finale that ensured this game will go down as an all-time classic.

The Vikings' hopes looked to be over when they faced fourth and 18 on their own 27-yard line with two minutes remaining, only for Jefferson to produce an astonishing show of athleticism to leap and bend backwards to snatch a desperation throw away from the clutches of Bills defender Cam Lewis and keep the drive alive.

Six plays later, after two more completions to Jefferson, the Vikings had fourth down at the Bills' one-yard line. Dalvin Cook's drop of a Kirk Cousins pass looked to have sealed the game for Buffalo, but the Bills were flagged for offside. The Vikings did not take their second chance, though, with Cousins stopped short on a quarterback sneak.

Incredibly, however, the Bills likewise could not execute a quarterback sneak from their own goal-line, Allen fumbling the snap into the hands of Minnesota linebacker Eric Kendricks for a go-ahead touchdown.

Allen still had 36 seconds to force overtime and, with the help of a hugely controversial diving catch from Gabe Davis, he did just that, setting up Tyler Bass for a game-tying 29-yard field goal.

The Vikings won the coin toss and, though they again failed to find the endzone after a stunning 24-yard throw from Cousins to Jefferson put Minnesota on the Buffalo two-yard line, the boot of Joseph gave them the lead.

Minnesota's profligacy meant Allen had the chance to win the game with a touchdown, but having driven the Bills to the Vikings' 20-yard line, Allen threw his fourth red-zone interception in two games to Patrick Peterson as Kevin O'Connell's visitors held on to triumph and move to 8-1. A second straight loss drops the Bills to 6-3.

Chiefs in cruise control

While the Bills, their primary AFC rivals, lost the game of the year, the Kansas City Chiefs enjoyed a much calmer afternoon, easing past the Jacksonville Jaguars 27-17 thanks to a four-touchdown day for Patrick Mahomes.

They now have the lead of the AFC at 7-2, with the Miami Dolphins their closest challengers at 7-3 as a 39-17 win over the Cleveland Browns moved Mike McDaniel's team to the top of the AFC East ahead of the Bills, who are now third in their division. The Tennessee Titans are 6-3 after a 17-10 defeat of the Denver Broncos.

Fields heroics not enough for Bears

Justin Fields is emerging as one of the best young quarterbacks in the NFL over recent weeks, and he delivered another scintillating showing for the Chicago Bears versus the Detroit Lions.

Fields threw for 167 yards and two touchdowns and rushed for 147 yards and another two scores, including an incredible 67-yard scamper in the fourth quarter. However, a missed extra point gave the Lions a chance to win with a touchdown, and Jamaal Williams clinched it for Detroit with a one-yard run that sealed a 31-30 triumph.

The Bears made unwanted history in defeat, becoming the first NFL team ever to score at least 29 points in three consecutive games and lose all three.

George Russell was lauded by team-mate Lewis Hamilton after winning the Brazilian Grand Prix, with the first-time Formula One race winner left "speechless" by his success.

Having won Saturday's sprint race, Russell led from the start in an eventful race on Sunday, coming out on top after two restarts following safety cars at the Interlagos Circuit. 

Russell had to fend off Hamilton – who had earlier clashed with Max Verstappen but come away largely unscathed and unpunished – after the second safety car, but there was no bad blood between the Mercedes duo at the end.

"What an amazing feeling," said Russell after sealing Mercedes' first win of the season. "Just a huge thank you to the whole team for making this possible. 

"It has been an emotional rollercoaster this season. This was a tough race, I felt in control.

"Lewis was super-fast and when I saw the Safety Car, I thought this is going to be a really difficult end, he put me under so much pressure.

"I am speechless. On the in lap, all of these memories start flooding back, starting with my mum and dad at go-karting and going through to all of the support I have had from the rest of my family, my girlfriend, my trainer, my manager.

"The list is endless. I can't thank them all enough, I am super proud."

Hamilton said: "A huge congratulations to George. What an amazing drive he did today.

"He did an amazing qualifying yesterday, so he truly deserves it. To my team, so proud of everyone back at the factory and here. This is an incredible result. 

"We’ve worked so hard through this year to get a 1-2 and to get a win, and so this is hugely deserved by everybody so a huge thank you."

On his collision with old rival Verstappen, who received a five-second time penalty, Hamilton added: "What can I say, you know how it is with Max."

The harmony in the Mercedes camp was not replicated in the other teams. 

While Red Bull's Sergio Perez was left infuriated by Verstappen, who refused to hand sixth place back to the Mexican after failing to overtake Fernando Alonso, Charles Leclerc also wanted Ferrari to concede Carlos Sainz's place on the podium to boost his chances of finishing second in the world championship.

Leclerc will now head into the final race in Abu Dhabi on level points with Perez.

"I think we can be happy with that," said Sainz. "It is a shame that Mercedes are so quick but congratulations to George."

Tony Finau collected the third win from his past seven PGA Tour starts as he cruised to a convincing four-stroke triumph at the Houston Open on Sunday.

Finau's four-stroke lead was the same buffer he held coming into the final trip around Memorial Park Golf Course after posting rounds of 65, 62 and 68.

After winning back-to-back events in July at the 3M Open and the Rocket Mortgage Classic, Finau – who finished with a final-round score of 16 under – has now won more titles in his past seven starts than he did in his first 211 to begin his career (two).

Speaking to NBC after stepping off the final green, Finau admitted he was not comfortable in such an unfamiliar position with a giant lead.

"It feels great – honestly, on the first hole I didn't know if I had it in me today," he said. "It was one of those days where I just fought, and fought, and I made a lot of nice putts on the front-nine to calm me into things.

"I've never been in this position before, with that big of a lead with nine holes to play. A lot of new nerves, I would say, but overall as the round went on I felt better, and I'm just happy to get the 'W' today.

"I've always had belief, but the confidence when you win is contagious. I've always been a very hopeful person, I work extremely hard on my body and my game, and now I'm starting to bear the fruits of that labour. It feels amazing to have that be the case.

"You never know what's going to happen in this game, but you always try to put your best foot forward, that's what I've done over the years, and I'm starting to put together a pretty full-package game."

Alone in second place at 12 under was Tyson Alexander, who had never previously finished better than tied for 44th in his seven PGA Tour starts.

Ben Taylor was the only player at 11 under in third, and there was a further three-stroke gap to the rest of the field.

World number two Scottie Scheffler finished tied for ninth at six under for his second consecutive top-10 finish, while former world number one Jason Day was one further back.

Sergio Perez hit out at Max Verstappen after his Red Bull team-mate refused to hand him sixth place at Sunday's Brazilian Grand Prix, saying: "If he has two championships, it's thanks to me".

Verstappen overtook Perez following a late safety car at the Interlagos Circuit to take sixth, having been encouraged by his team to challenge Ferrari duo Carlos Sainz and Charles Leclerc in third and fourth, as long as he could first overtake Fernando Alonso.

With Verstappen unable to take points off the Ferraris, he was told to hand his position back to Perez, who is battling Leclerc for second place in the drivers' championship standings.

However, the two-time world champion failed to do so before telling race engineer Gianpiero Lambiase: "You guys don't ask that again to me, okay? Are we clear about that? I have given my reasons."

Perez was infuriated by Verstappen's failure to give way, exclaiming over team radio: "It shows who he really is."

Speaking to Sky Sports after finishing seventh – a result which leaves him level with Leclerc in the standings, Perez said: "I was told to let him by and that I was going to get the position back.

"I don't know what the complications were on his side. I have no idea, maybe you should ask him about it.

"I have nothing to say, really. After all I have done for him, it is a bit disappointing, to be honest. I am really surprised."

Perez went further when asked about the incident in Spanish by ESPN, declaring: "If he has two championships, it's thanks to me."

However, Verstappen told Sky Sports he remained willing to support Perez in next week's final race of the season, while refusing to explain his decision not to hand the place back. 

"I have my reasons for that, we just discussed that [in the debrief]," he said. "I think it was good that we finally just sat together and talked about it, and we'll just move forward from here.

"If we go to Abu Dhabi [next Sunday] and he needs support, it is not the end of the world. It is all about who finishes ahead, anyway. 

"If he needs the help, I am there, but it is good that we first talked about it now and cleared everything that was there and why I didn't do it."

Red Bull team principal Christian Horner, meanwhile, insists the team will prioritise Perez's battle for second next time out.

"We will go to Abu Dhabi to get Checo the second place and Max will support that," Horner told Sky Sports. "We won't talk about what happens internally, but the drivers shook hands on it.

"We work as a team, we race as a team and our priority is to help Checo get second in the championship. We will do the best we can to achieve that and if Max can help in any way, he will do."

George Russell led from the start in a dramatic, stuttering Brazilian Grand Prix on Sunday to clinch his first Formula One win, holding off Mercedes team-mate Lewis Hamilton.

Having won the sprint race at the Interlagos Circuit on Saturday, Russell kept his composure while those around him clashed and collided in a race full of incident.

The race was halted by a red flag on the first lap, with Daniel Ricciardo crashing into Kevin Magnussen, and Hamilton was perhaps fortunate to come away unscathed and unpunished after a collision with Max Verstappen following the restart – which saw the world champion handed a five-second time penalty.

A second safety car was brought out after Lando Norris lost power on the track with 19 laps remaining, but another fine restart from Russell saw him see off Hamilton and claim a deserved maiden victory.

Sunday's race was dramatic from the start as Ricciardo and Magnussen crashed out as early as Turn 8 – and the restart brought another collision, this time between old rivals Hamilton and Verstappen.

Hardly strangers to battles and bruises down the years, Hamilton and Verstappen tussled on Turn 2.

Verstappen got around the seven-time world champion on Turn 1, but despite appearing to have the racing line on the inside on the next corner, it was the Dutchman who was punished after a significant collision – though both cars were able to stay in the race.

Charles Leclerc was also sent spinning into the barrier after an incident involving Norris, but the Ferrari was able to continue.

Hamilton recovered swiftly, with the Mercedes driver clawing his way ahead of Norris, Carlos Sainz and Sergio Perez.

A three-second loss in the pits cost Verstappen further time, though the Red Bull's speed was on show as he quickly cruised back into the points.

However, Norris' vehicle failed him on lap 52, resulting in a second full safety car. Having seen his 11-second lead cut by that stoppage, Russell might have lost his nerve, but a wonderful restart propelled him out of Hamilton's DRS range.

Sainz came in third, leaving Leclerc dismayed, though the day belonged to Mercedes, who are aiming to cap a frustrating season with a flourish.

Team-mates tussle

There are few friends in F1, it would seem. While Hamilton was happy to congratulate his team-mate Russell on a maiden F1 success, there was frustration within the ranks of Ferrari and Red Bull.

Leclerc was begging Ferrari to instruct his team-mate Sainz to give way, and concede a podium place, in order to boost his chances of finishing second in the world championship.

Verstappen, meanwhile, ignored Red Bull's instructions to hand sixth place back to Perez if he was unable to pass Fernando Alonso. "I have given you my reasons," Verstappen said on the team radio. 

Magnussen's weekend ends in sorrow 

Haas driver Magnussen took a shock pole in qualifying on Friday, though he went down to eighth in the sprint race. However, by Turn 8 on the first lap, the 30-year-old had crashed out.

Ricciardo, who could now face a grid penalty in his last race for McLaren, was to blame for clipping the back of Magnussen's car, with the Australian compounding the issue when he failed to avoid the spinning Haas, sending both vehicles into the wall and out of the race.

The Tampa Bay Buccaneers strengthened their grip on first place in the NFC South as they survived a fourth-quarter fightback from the Seattle Seahawks to prevail 21-16 in Munich.

Tampa Bay went into the NFL's first regular-season game in Germany having got back on track with a last-gasp 16-13 win over the Los Angeles Rams and on top in their division despite an underwhelming 4-5 record.

For three-and-a-half quarters, there was little sub-par about the Buccaneers' performance at the Allianz Arena, where they led 21-3 with under nine minutes remaining.

Geno Smith threw touchdowns to Tyler Lockett and Marquise Goodwin to cut their advantage to 21-16, but Tom Brady delivered a clock-killing final drive to seal the game for the Bucs, who improve to 5-5, a game ahead of the 4-6 Atlanta Falcons with a tie-breaking head-to-head win in the NFC South. The Seahawks drop to 6-4.

After a scoreless first quarter, the Bucs took the lead at the end of a 13-play drive, Brady connecting over the middle with Julio Jones, who galloped into the endzone for a 31-yard touchdown.

While Smith and the Seahawks' offense continued to struggle, Brady looked increasingly comfortable and led another 13-play drive that was capped by a Leonard Fournette rushing touchdown to put Tampa Bay up 14-0.

Seattle responded in the third quarter with a 55-yard field goal but did not look like stopping the Bucs' offense until a remarkable trick play saw Fournette intercepted by Tariq Woolen while trying to throw to Brady.

But Smith fumbled in the red zone on the subsequent drive and Brady's four-yard touchdown pass to Chris Godwin seemingly put the game beyond doubt.

Smith connected with Lockett to give Seattle hope that was furthered by Goodwin's diving touchdown grab after a Cody Barton interception.

However, the Bucs gained three first downs on the final drive to end any prospect of a turnaround in Bavaria.

Scotland coach Gregor Townsend says his side missed "the best opportunity in our history" to defeat New Zealand for the first time on Sunday.

A Stuart Hogg penalty try and Darcy Graham crossing over, coupled with a trio of penalties for Finn Russell, helped Scotland into a 23-14 second-half lead at Murrayfield.

But points from the boot of Jordie Barrett and a Jack Dempsey sin-bin allowed the All Blacks to fight back before Scott Barrett and Mark Telea bundled over to maintain New Zealand's streak in Scotland.

The All Blacks have not lost in 32 Tests against Scotland, stretching back 117 years, and Townsend acknowledged his team squandered a glorious opportunity after a 31-23 defeat.

"We're disappointed. There was so much to be proud of but we didn't see it through," he told Amazon Prime.

"It was a show of resilience after going 14-0 down to one of the best teams in the world, but we didn't get the win.

"You don't get to play New Zealand very often and that's the best opportunity in our history we've had to beat them."

The manner of defeat added greater frustration for Scotland, given they led 17-14 against New Zealand at half-time for just a third time in history, with the other two occurrences coming in 1905 and 1990.

Scotland captain Jamie Ritchie acknowledged the missed opportunity after the match, though he dedicated the performance to Doddie Weir, who was in attendance to mark five years since the launch of his charity that raises awareness of motor neurone disease.

"It's tough to be on the wrong side of the result. We were there or thereabouts for 70 minutes," Ritchie said. "It's some of the best rugby we've played over the last three weeks and I'm so proud of the players.

"We're glad we could put on a decent show for Doddie [Weir], just a shame we couldn't get the win. We spoke about being brave today and nothing defines brave more than Doddie."

Ian Foster had come under scrutiny for an underwhelming 2022 for the All Blacks, though praised New Zealand's fightback after they collected their sixth straight Test win.

"It was a tough game. I thought Scotland were tremendous, they put us under a lot of pressure," the All Blacks coach said. "Our bench was strong and that strength and composure was important.

"It was a high penalty count game and that allowed Scotland to get into our half too often, so we need to work on that.

"It would have been easy for us to panic in the last 15 minutes and [captain] Sam Whitelock deserves a lot of credit for keeping the boys calm."

Casper Ruud opened his ATP Finals campaign with a 7-6 (7-4) 6-4 triumph over Felix Auger-Aliassime in Turin.

The victory put Ruud top of the Green Group, with the pool's two other players, Rafael Nadal and Taylor Fritz, set to face off later on Sunday.

A tight first set saw each game go to serve as it went all the way to a tie-break, with Ruud – this year's beaten US Open finalist – finding a crucial break at 3-2 up, giving him the momentum to nose ahead.

They continued to be closely matched in the second set too, though Ruud again managed to break Auger-Aliassime at a critical juncture in the match.

With the set tied at three apiece, ATP Finals debutant Auger-Aliassime double-faulted at 40-15 down on his own serve to put Ruud within two games of victory.

The world number four took full advantage, who is making his second appearance in the season-ending tournament, kicking on to secure a straight-sets success without offering a single break point to begin his tournament in impressive fashion.

Tommy Fleetwood edged out Ryan Fox in a dramatic finish to defend his Nedbank Golf Challenge crown and end a three-year winless run on the DP World Tour.

Fleetwood and Fox went into the final round three shots behind Rasmus Hojgaard and Thomas Detry at Gary Player Country Club in Sun City, where play was suspended on Sunday due to thunderstorms.

The leaders had only managed five holes before the delays, though Fleetwood raced into the ascendancy after the restart as he carded a five-under 66, including an eagle and four birdies to triumph.

"It has been a great week," Fleetwood said. "I already had so many amazing memories with this place and felt like I had such a great connection to it, so this [win] just added to that."

Victory for Fleetwood was never a certainty until the 18th hole, though, as a wayward tee shot saw Fox bogey the last hole to finish on 10-under, one shot behind the Englishman.

An erroneous drive meant Fox relinquished the chance to not only win the event but also to jump above Rory McIlroy at the top of the season-long DP World Tour rankings.

"I played great and didn't miss a shot until the 18th," Fox said. "I certainly would've like to have played the 18th a little bit better and made Tommy work a little bit harder, but it's an incredibly tough golf course to play down the stretch.

"All of us were there or thereabouts with three holes to play, but Tommy was the one who held it together. Fair play to him. If you had given me second at the start of the week, I definitely would've taken it."

Shubhankar Sharma finished on nine-under to claim third, with Richie Ramsay a further shot behind in fourth as Fleetwood secured his sixth DP World Tour title.

It was also his first triumph since winning the Nedbank Golf Challenge in 2019, with the past two editions cancelled due to the coronavirus pandemic, as Fleetwood climbed to fourth in the rankings ahead of the season-ending DP World Tour Championship.

Mark Telea scored two tries on debut as New Zealand mounted a second-half comeback to maintain their unbeaten streak over Scotland after a 31-23 victory at Murrayfield.

Late tries for Scott Barrett and Telea saw the All Blacks defend their perfect record against Scotland, who squandered a 23-14 lead as they failed to defeat the All Blacks for a 32nd straight Test.

The All Blacks raced into a two-try advantage as debutant Telea's driving run teed up Samisoni Taukei'aho before the winger crossed over himself four minutes later on Sunday.

But Scotland fought back amid a frenetic start as Anton Lienert-Brown was sin-binned for a Stuart Hogg penalty try, with Darcy Graham capitalising on the one-man advantage to dive over in the 14th minute.

Finn Russell's penalty ensured Scotland led New Zealand at half-time in a Test for just a third time in history, before the fly-half added another six points with his boot from range after the interval.

However, a Jordie Barrett penalty and Jack Dempsey sin-bin saw the All Blacks battle back before Scott Barrett and Telea bundled over to keep their 117-year unbeaten run against Scotland going.
