Cleveland Browns quarterback Baker Mayfield has been ruled out of their clash with the Denver Broncos.

Mayfield is dealing with a torn labrum in his left shoulder but had previously insisted he would be fine for the visit of the Broncos.

However, his streak of 51 consecutive starts will come to an end as the Browns look to improve to 4-3 on the season.

Instead, Case Keenum will get the start under center.

"We have full confidence in him [Keenum] to lead us and do the things necessary to put us in position to win," Browns coach Kevin Stefanski said.

"Baker fought really hard to play, he's a competitor and obviously wants to be out there but just couldn't make it on a short week.

"We know he will continue to do everything in his power to return as quickly as possible."

In addition to Mayfield, the Browns will be without both of their starting running backs.

Nick Chubb will miss his second successive game because of a calf injury, with Kareem Hunt having been placed on injured reserve with a similar issue.

The Browns could again be minus both of their starting offensive tackles, Jack Conklin and Jedrick Wills, while wide receiver Odell Beckham Jr. sat out Tuesday's practice because of a shoulder issue.

Having dropped successive games to the Los Angeles Chargers and the Arizona Cardinals, the deck could be stacked against Keenum in his bid to help the Browns avoid another damaging defeat.

Pohang Steelers came from behind to book their AFC Champions League final spot with a 5-4 penalty shootout victory over 10-man Ulsan Hyundai after a 1-1 draw.

Alex Grant nodded in a late equaliser before Pohang scored each of their five penalties, with Davy Bulthuis missing for Ulsan.

A cagey first half saw just two clear-cut chances, with Lee Seung-mo heading against the left post in the sixth minute for Pohang before Ulsan should have gone ahead on the stroke of half-time as Yun Il-lok headed a free-kick wastefully wide after being found unmarked at the back post.

The deadlock was broken seven minutes after the restart when Yoon Bit-garam's low ball across the face of goal was spilled by Jun Lee, allowing Yun to pounce on the loose ball and fire in from close range.

Pohang threw men forward in search of an equaliser but were nearly caught out as Yoon struck the right post from Lee Dong-gyeong's cutback, with Lee Jun rooted to the spot.

Ulsan were reduced to 10 men as captain Won Du-jae slid in on Lim Sang-hyub with his studs showing, earning himself a straight red card with over 20 minutes of normal time still to play.

The Ulsan midfielder's error of judgement proved costly as Pohang's man advantage paid dividends, with defender Grant heading in off the post in the top-right corner to level the scores with one minute of normal time remaining, forcing extra-time and then spot-kicks.

Ulsan centre-back Bulhuis was the only player to miss from the spot, blazing over the bar, although Lee Chung-Yong saw a tame stutter-stop effort easily saved, but was allowed to re-take it as Jun Lee was off his line.

Pohang scored all five spot-kicks, with captain Kang Sang-woo rifling the final penalty inside the left-hand post to spark wild celebrations.

The K League 1 side will face Saudi Arabian outfit Al Hilal in the final on November 23.

Lewis Hamilton will look to bounce back from frustration in Turkey as he returns to one of his favourite tracks at the United States Grand Prix this week.

The drivers' championship battle between Hamilton and Max Verstappen continues to be closely fought, with just six races left in the 2021 season.

Red Bull driver Verstappen moved back into the lead in Istanbul and comes to Austin with a six-point advantage over Hamilton, who is seeking a record-breaking eighth world title.

Hamilton took an engine penalty in Turkey and limited the damage to his rival, but was frustrated with his own team over a strategy call that he felt may have cost him a podium.

The trip to the USA therefore comes at a good time for the Briton, who has won this race a record six times.

Only in Hungary, Great Britain (both eight) and Canada (seven) has Hamilton won more times and he did not have the chance to add to his tally in 2020 as the event was not held due to the coronavirus pandemic.

Hamilton has eight podiums from his nine USA races, and the only time he did not make the top three he still finished fourth in 2013.

He also sealed the third and sixth of his seven world titles in Austin, his 2015 race win and second-place finish in 2019 giving him those successes.

While Verstappen leads the drivers' battle, Mercedes do still top the constructors' standings and will hope a resurgent Valtteri Bottas can help Hamilton to continue the team's strong track record at the venue.

LAST TIME OUT

Strategy was key in wet conditions at the Turkish Grand Prix, with Hamilton left frustrated by Mercedes' decision to pit late and help Verstappen, who ended up in second place, reclaim the championship lead.

Having been fastest in qualifying but handed a 10-place grid penalty due to his engine change, Hamilton saw team-mate Bottas start in first place.

It was a lead Bottas only relinquished briefly to Charles Leclerc, though the Finn regained it with a brilliant move on the inside of the Ferrari with 11 laps remaining to claim his first win of the season.

Hamilton's decision to hold off pitting in the wet conditions was what prompted debate between driver and the Mercedes pit wall.

Well in the hunt for a podium place in the 51st lap, Hamilton was finally instructed to come in which meant he was forced to settle for fifth behind Bottas, Verstappen, Sergio Perez and Leclerc.

WHAT TO EXPECT IN USA

Hamilton's fine record in the United States means it is he who goes into the race weekend as the narrow favourite to strike the next blow in a thrilling title battle on Sunday.

Verstappen has solid form at the Circuit of the Americas too, though, with past finishes of second, third and fourth.

The Dutchman is optimistic of taking the fight to Mercedes as he targets a first Austin win, as he looks to end a run of three races without a victory in 2021.

That title race will again be the main focus, with both Mercedes and Red Bull hoping their second drivers can get in on the action to help Hamilton and Verstappen respectively.

Bottas claimed his first win of the year last time out and has three podiums from his last four outings, while Perez finally ended a miserable eight-race run without a top-three finish in Turkey.

Lando Norris is one point away from matching his total from the 2019 and 2020 seasons combined and will hope McLaren can be more competitive this week. 

They are locked in a close battle with Ferrari for third place in the constructors' championship, with the British team just 7.5 points ahead of their Italian rivals.

TOP FIVE OPTA FACTS

Qualifying key - The past 10 winners of the United States Grand Prix came from the first row of the grid - six from pole position and four from second place.

Fond memories – The last time F1 raced in the United States (2019), Hamilton reached his 150th career podium. He has since moved on to 176 top-three finishes, an F1 record total.

Bottas barrier – The Finn is looking to get a pole position and race win double in consecutive grands prix, a feat he has never achieved before. He did get pole and win the race at the 2019 edition of this event. 

Mercedes mark – The team have six poles in their last six races in the United States and another here would see them equal Ferrari on seven poles in the country. Only Lotus (10) have recorded more than Ferrari.

Austin aces – Mercedes have had a podium finisher in each of the last six USA races, winning five of those events and finishing with a one-two in four of them, including the last one in 2019.

Australian Minister for Immigration Alex Hawke insists Novak Djokovic would need to be fully vaccinated against COVID-19 in order to enter the country and defend his Australian Open title.

The Serbian is the top-ranked player in the world and could move clear of Rafael Nadal and Roger Federer for grand slam titles if he can claim his 21st at Melbourne Park.

However, Hawke's comments regarding vaccination requirements cast doubts over Djokovic's participation, with the 34-year-old previously declining to reveal his vaccination status.

"You'll need to be double vaccinated to visit Australia," Hawke said to Australian Broadcasting Corporation radio. "That's a universal application, not just to tennis players. I mean that every visitor to Australia will need to be double vaccinated.

"I don't have a message to Novak. I have a message to everybody that wishes to visit Australia. He'll need to be double vaccinated."

With recent reports suggesting that over a third of professional players have yet to be fully vaccinated, a significant number could be denied the chance to play in the opening grand slam of 2022.

The men's ATP and women's WTA tours have attempted to encourage players with reservations to get the vaccine, and Tennis Australia explained that it was working with government authorities regarding conditions for the tournament.

"Our understanding is that the details around international visitors entering the country are yet to be decided and we hope to have more information soon," Tennis Australia said in a statement.

Australia's health minister Greg Hunt defended the ruling, explaining that the decision had been taken with the safety of the country's citizens in mind.

"The [rules] apply to everyone without fear or favour," Hunt said. "It doesn't matter whether you are number one in the world or you are anything else."

Djokovic, who withdrew from the Indian Wells Masters this month, has won nine of his majors at the Australian Open.

Atletico Madrid have confirmed Marcos Llorente aggravated a thigh injury in Tuesday's Champions League defeat to Liverpool and is being assessed.

The 26-year-old initially sustained the injury during Atletico's 2-0 win over Barcelona on October 2 and was forced to pull out of Spain's squad for their recent World Cup qualifiers.

He was not fit enough to start the dramatic 3-2 loss at the hands of Liverpool but was introduced from the substitutes' bench for the final 10 minutes.

Llorente pulled up late on in the game and is now facing another possible spell on the sidelines.

A statement on Atleti's official website on Wednesday read: "Marcos Llorente has suffered a relapse in the muscle injury he suffered in his right thigh.

"The player has undergone tests at the University of Navarra Clinic, in which it has been detected that the scar from his previous injury had partially opened.

"At the end of Tuesday's game against Liverpool, the player expressed discomfort to the club's medical services in the same area where he had suffered his injury.

"Today he will begin medical and physiotherapy treatment and will soon resume the rehabilitation process. His return to competition is pending evolution."

The versatile Llorente has featured in all 11 of Atletico's matches this season, starting each of those prior to the European clash with Liverpool on Tuesday.

Only goalkeeper Jan Oblak (990) has played more minutes for the LaLiga champions in all competitions this term than Llorente's 886.

While he has yet to score or assist a goal, the 12 chances created by Llorente is bettered only by Rodrigo de Paul (13) among Atleti players.

Diego Simeone's men host surprise leaders Real Sociedad on their return to LaLiga action on Sunday following a three-week break from domestic action, before travelling to Levante four days later.

Andy Murray says he will never forget his memorable clash with Frances Tiafoe at the European Open in Antwerp.

The former world number one saved two match points in the first round match and eventually triumphed 7-6 (7-2) 6-7 (7-9) 7-6 (10-8) in three hours and 45 minutes.

Murray's victory in an epic clash was the longest three-set match of the 2021 ATP season.

The battle had so many twists and turns that Murray, a veteran of 897 matches on tour, ended up having a long debrief with Tiafoe in the locker room afterwards.

Murray revealed it was the first conversation of that nature he had been involved in for more than a decade.

Indeed, the Briton only remembered going back over a match with one of his opponents twice before.

"I spent probably 30 minutes in the locker room afterwards just chatting to Frances," Murray said. "I had a long chat with Frances afterwards so I'll probably remember that and then the embrace at the end. 

"I guess so much went into it that I don't remember loads of points in the match, but obviously the end was special. 

"I've never played a match like that on the tour really. In the locker room we had a much more in-depth chat about tennis - that was kind of rare I would say. 

"I think maybe twice I've had that conversation in the locker room.

"Once was with [Jurgen] Melzer at the US Open after I beat him in five sets [in 2008] and we chatted a bit about the match.

"And then once after playing Jarkko Nieminen [at Wimbledon in 2010] because we were waiting to speak to the Queen after we played." 

Murray faces a tough test in the last 16 as he is due to do battle with second seed Diego Schwartzman.

He hit 21 aces against Tiafoe and totalled 46 winners to just 21 unforced errors, but Tiafoe was also in form with 51 winners to 25 unforced errors.

"The margins were so fine," added Murray. "I served particularly well at the end, which helped, and when he missed his first serve on that match point I was able to capitalise on that.

"There's obviously so much that goes into a match like that."

Schwartzman will go into the next match fresher than Murray as the Argentine received a first-round bye due to his seeding.

Steve Bruce has left Newcastle United by mutual consent following the club's Saudi Arabian-backed takeover.

Bruce was appointed in July 2019 by Newcastle and celebrated his 1,000th match as a manager with a 3-2 defeat against Tottenham on Sunday.

The Magpies sit in 19th, one point ahead of Norwich City, as Bruce becomes the second Premier League manager to leave his post this season following Xisco Munoz's dismissal by Watford.

Graeme Jones will lead Newcastle on interim basis, starting with Saturday’s trip to Crystal Palace, and will be supported by the coaching team of Steve Agnew, Stephen Clemence, Ben Dawson and Simon Smith.

Newcastle revealed that the process of recruiting a new head coach has started and an appointment will be announced in due course.

Former Argentina head coach Alfio Basile has criticised "messy" Paris Saint-Germain's use of Lionel Messi and says the Ligue 1 side have "a weak defence".

Barcelona's financial difficulties forced Messi to find a new club, eventually joining PSG on a free transfer in August. 

The six-time Ballon d'Or winner got off to a slow start in France, scoring just once in his first four appearances across all competitions and missing several games due to injury.

Basile, who had two spells in charge of Argentina (1991-1994 and 2006-2008), winning two Copa Americas and a FIFA Confederations Cup in a successful first stint, hit out at how PSG boss Mauricio Pochettino was deploying Messi.

"The problem that Messi has is that at PSG, he is playing on the right and with Argentina, he plays everywhere, he makes everyone play." Basile said to SuperMitre.

The former Barca superstar, who won the Copa America with Argentina in July and was named the player of the tournament after registering the most goals and assists, enjoyed a breakthrough evening for his new club as PSG beat RB Leipzig 3-2 on Tuesday, scoring twice.

Basile was scathing in his assessment of the Ligue 1 giants as a team, however, pointing out their defensive organisation as a particular problem.

"PSG have a very weak defence and are very messy," Basile added.

PSG have the seventh-worst expected goals against total in the Champions League so far this season (5.39) but have only conceded three goals, keeping one clean sheet.

Australia fast bowler James Pattinson has retired from international cricket less than two months before the start of the Ashes.

The 31-year-old's start to the season has been delayed by COVID-19 lockdowns and an injury and the quick has decided to call time on representing his country.

Pattinson played for Australia 40 times and had been expected to add to his 21 Test appearances in the upcoming series against England, which is due to start at The Gabba on December 8.

"Leading into pre-season I really wanted to give the Ashes a crack but in the end, I haven't had the preparation I would have liked heading into the coming season," Pattinson said in a statement.

"If I was to be part of the Ashes I would need to do myself and my team-mates justice. I didn't want to be in a position of battling with my body when you need to be 100 per cent fit and ready to go at any time. That would not be fair to myself or the team.

"It was then I felt that instead of trying to play at the very highest level, knowing I have only got three or four years of cricket left, I would focus more on Victoria, helping the young guys develop, perhaps some cricket in England and spending more time with my family."

Pattinson made his Test comeback against England in 2019 following three-and-a-half years out of the side, having undergone surgery on a serious back injury.

He claimed 81 Test wickets at an average of 26.33, picking up four five-wicket hauls.

LeBron James says he is "not worried at all" about Russell Westbrook after he suffered first-game jitters in a losing Los Angeles Lakers debut on the opening night of the NBA season.

Westbrook cut a disconsolate figure following a tough bow as Stephen Curry inspired the Golden State Warriors to a 121-114 victory at Staples Center on Tuesday.

Nine-time NBA All-Star Westbrook finished with only eight points, five rebounds, four assists and four turnovers in a debut that did not go to plan.

James, who got his season under way with a double-double of 34 points and 11 rebounds, has no concerns about Westbrook following such a disappointing bow for the 2017 MVP.

"I think it was just first-game jitters. I don't put too much into it," James said of Westbrook's performance. 

"There was a lot going through his mind, being a kid from LA and watching the Lakers growing up, then however many years down the road now you're putting on a Laker uniform, you're stepping into Staples Center.

"I can only imagine how many friends and family have contacted him in the last 48 hours wondering if they can come and see his first game as a Laker. Those demands will quieten down as the season goes on, so I'm not worried about Russ at all. He just needs to worry about himself and not worry about the outcome."

James revealed he told Westbrook not to dwell on his below-par display.

He said: "I told Russ just don't be so hard on yourself, it's one game. That's the one thing I tried to get through to him. Go home and see the three babies that he has.

"They might be asleep, but it will put a smile on his face. He can go home and see a beautiful wife and family and realise it's not that bad."

Curry put up a triple-double of 21 points, 10 assists and 10 rebounds in a great start to the campaign for the Warriors.

Stephen Curry may have produced his eighth career triple-double and first since 2016 but he says he "played like trash" in Tuesday's NBA season-opening 121-114 win over the Los Angeles Lakers.

Curry's Golden State Warriors made a statement as they stunned the Lakers, with the star point guard contributing 21 points, 10 rebounds, 10 assists and three steals.

The two-time NBA MVP only managed five-from-21 from the field, shooting at 23.8 per cent, with nine of his points coming from the stripe.

"I played like trash, shot the ball terribly," Curry told ESPN after the game.

The Warriors turned in a 38-29 final quarter to claim the win, scoring 46 points in the paint for the game, compared to the Lakers' 34.

Golden State had a good spread of contributors, while the Lakers relied on LeBron James (34 points, 11 rebounds and five assists) and Anthony Davis (33 points, 11 rebounds and two assists), as Russell Westbrook battled on debut, finishing with eight points, five rebounds and four assists.

Curry added: "If we can win a game like that, where we create some good shots and stick with it defensively, against a pretty good team, that is a pretty good omen.

"We've got to learn from our mistakes, quit turning the ball over, make more shots, we'll be good.

"This is a good feeling. We had a lot of excitement coming into the season. New cast of characters mixed with our core. We weathered the storm tonight."

New Warriors additions Nemanja Bjelica, Andre Igoudala, Otto Porter Jr and Moses Moody all got minutes and contributed. Bjelica added 15 points and 11 rebounds from 26 minutes, while veteran forward Igoudala scored 12 points from 23 minutes.

Jordan Poole also stepped into the starting line-up to score 20 points, including 16 in the second half, and Curry was bullish that the team would continue to gel as they get into the season.

"That's what early season is all about," Curry said. "Obviously there was a lot of hype about this game. We want to be in a playoff-like atmosphere like this.

"We have a lot to learn and grow. Our chemistry is solid, in terms of what we're trying to do. When you have to go execute it, it's a different animal. I like learning lessons in wins."

James Harden said he is "not planning on leaving" the Brooklyn Nets, despite the contract deadline passing without a new deal.

Harden and the championship-chasing Nets did not reach an agreement over a contract extension prior to Monday's deadline in the NBA.

The former MVP – entering the third season of a four-year, $171.1million deal signed with the Houston Rockets before his blockbuster trade to the Nets last season – is now set to enter unrestricted free agency at the end of the 2021-22 campaign.

But the 32-year-old superstar dismissed the possibility of leaving Brooklyn after the Nets lost 127-104 to reigning NBA champions the Milwaukee Bucks in Tuesday's season opener.

"The contract, the money is going to be there. I'm not planning on leaving this organisation and the situation that we have," Harden said, having scored 20 points, eight rebounds and eight assists in Milwaukee.

"So my focus, honestly, is just focus on the season and then winning the championship. The contract and all that stuff will work itself out, but my focus is going to be locked on this season."

Harden added: "Last year was a whirlwind for me individually, as far as my health and playing. So this year I feel like I need to come back and show I am one of those ones. So I've got a lot to prove myself and that's all I'm worried about and focused on.

"I love it here. Myself and [Nets owner Joe Tsai, Clara Wu-Tsai, general manager Sean Marks and head coach Steve Nash].

"From top to bottom the communication has been unbelievable, it's been amazing. I feel at home. It's nothing to worry about. For me individually I just want to focus on this year and that's it."
