Los Angeles Rams quarterback Matthew Stafford has entered the concussion protocol putting him in doubt for Sunday's game against the Arizona Cardinals.

Rams head coach Sean McVay confirmed on Wednesday that Stafford had entered the protocol on Tuesday with medical staff performing their "cleanup after the game" from Sunday's 16-13 loss to the Tampa Bay Buccaneers.

Stafford has not missed an NFL game since 2019, but if he is unavailable, John Wolford would be the Rams' starting quarterback.

"We'll take it a day at a time with him," McVay told reporters. "We're still anticipating and having the optimistic approach that there's a possibility that he'll be ready to go."

McVay added: "I know Matthew's going to do everything in his power to try to be able to be ready and we'll just take it a day at a time.

"But John's a guy that when he's been in these situations, he's stepped in and done a really good job. And it wasn't too long ago that he had to come in a game that we had to have to be able to get into the playoffs and he performed incredibly well."

McVay clarified that Stafford had not shown any indication that he was dealing with concussion symptoms during Sunday's game. He said medical staff "determined that they felt like that [entering protocols] was the best thing for him".

Stafford completed 13 of 27 passes for 165 yards and one touchdown with no interceptions against the Bucs. He was sacked four times in the game.

The 34-year-old Super Bowl LVI champion has a 68.4 per cent completion rate for 1,928 passing yards with eight touchdowns and eight interceptions this season.

The Rams are 3-5 and third in the NFC West, while the Cardinals are 3-6 and fourth in that division.

Diego Simeone urged Atletico Madrid to return after the World Cup with the intention of turning around their faltering season following another defeat.

Atletico were beaten 1-0 away to Mallorca on Wednesday, stretching their winless run to five matches across all competitions – they have never endured a worse streak during Simeone's spell in charge.

Up next is a tussle with minnows Almazan in the Copa del Rey on Saturday, but otherwise Atletico are now not due to play competitively again until after the World Cup.

Wednesday's defeat leaves Atletico sixth in LaLiga, although a big win for Rayo Vallecano against Celta Vigo on Thursday could push Simeone's men down a place.

Either way, the first half of the season has not gone to plan for Atletico, who will be without knockout European football in the new year for the first time since 2010-11.

"The pause of the championship will generate peace of mind to work, and to fully recover [injured players], whom we obviously need," Simeone told DAZN.

"I hope that after the World Cup they come back with the idea of reversing this difficult situation."

Despite the obvious issues for Atletico, Simeone actually seemed somewhat philosophical about their situation and Wednesday's performance.

While concerns remain, Simeone also saw elements that he liked, especially the team's attitude towards the end.

"To say that we have lacked forcefulness in all the games is a very simple excuse. We're making a lot of defensive mistakes that make games uphill battles for us, having to go looking to change the result and that creates complications for us," he later said in his post-match press conference.

"It's clear that little happened in the game in the first half. We couldn't solve a very simple plan in the best way and the game was played where [Mallorca] feel most comfortable.

"Defensively, [Mallorca's] work was very comfortable. In the first half we were looking for balls with more directness in order to be closer to the goal.

"Our changes gave us more vitality, freshness, a more dynamic way of approaching the game with speed on the flanks with [Antoine] Griezmann, [Thomas] Lemar's [ability to] break [the lines], and the appearance of [Sergio] Reguilon, who can give important things. But it was not enough.

"Reality makes us leave with a defeat that hurts and that obviously makes us have to work hard in the time we are going to have, because when LaLiga returns there will be complicated games.

"[But] the team never gave up, I never saw a team that didn't want to go for the game, and that gives me strength."

Chelsea manager Graham Potter believes Wednesday's 2-0 EFL Cup loss to Manchester City was a "step forward" for the Blues despite suffering their third defeat from their past four games.

The Blues have only won two of their past seven games under Potter, who replaced Thomas Tuchel in September, amid a poor run of form.

Potter made seven changes to his starting line-up from the side that went down 1-0 to Arsenal in the Premier League on Sunday but was enthused albeit disappointed by the defeat.

"I thought there were quite a few positives," Potter told reporters. "Obviously, we’re disappointed with the result but in terms of how we played, we created some good chances, there was a better structure and performance level.

"The team looked closer to what we want it to look like [compared to Arsenal]. The boys had great courage and they tried against a top team.

"Their goalkeeper got man of the match and I think that tells a little bit of the story. But overall, I think it was a step forward for us."

Potter's side go to third-placed Newcastle United in the Premier League on Saturday in their final game before the World Cup break. Chelsea are winless in four league games.

"We're concerned when we don’t get the results we want," Potter said. "Our performances have not been what we want either in the last couple of games. Tonight was a big step in terms of how we want to play, and we can get confidence from that.

"It’s a big game at Newcastle, 5.30 on the TV, it'll be a fantastic atmosphere. They’re doing really well, so it’ll be a tough game, but we have to try and go there and get the three points."

Potter was impressed with 18-year-old midfielder Lewis Hall, after the England youth international earned his second career start for the Blues.

Hall played 75 minutes and had a good chance saved by City goalkeeper Stefan Ortega late in the first half in an energetic display.

"I really enjoyed his performance," Potter said. "He took responsibility, took the ball in tight areas, attacked the box, and could’ve scored a couple of goals on another day.

"It was a really nice performance, a mature performance I thought. He is a quiet lad but goes about his work. I've been really impressed with him."

Jurgen Klopp says he remains "committed" to Liverpool amid rumours of Fenway Sports Group (FSG) potentially looking to sell the club.

The Reds beat Derby County on penalties after a goalless 90 minutes on Wednesday to reach the EFL Cup fourth round, but many of the questions after the match surrounded FSG's statement earlier in the week.

On Monday, The Athletic reported FSG was "inviting offers" to sell the club, but the Boston-based company later clarified they were willing to "consider new shareholders" while remaining "fully committed" to Liverpool.

When quizzed on whether a potential sale may affect his managerial position, Klopp told reporters: "For me it means nothing.

"Whatever happens, I really like how we work together with our owners, but if that would change, I'm committed to the club.

"As far as I know, they're looking for investors and I thought actually that makes sense.

"We work really close together with FSG. It was and is a great relationship until now and it will not change and whatever happens we will see and we will deal with it."

Asked whether the statement had any impact on his team's build-up to the game with Derby, Klopp replied: "No impact at all.

"It didn't distract the preparation at all. The players didn't ask me but if the players want to ask me, I can tell them everything."

When the press conference turned to events on the pitch, Klopp was effusive in his praise for backup goalkeeper Caoimhin Kelleher after his three shootout saves helped Liverpool see off League One Derby at Anfield.

Klopp made 11 changes from the weekend victory over Tottenham, and although Derby pushed his young side all the way to spot-kicks, Kelleher came up big to keep the holders' hopes of retaining the trophy alive.

Klopp was delighted for the 23-year-old after the match, saying: "We never hold him back, he is exceptional, absolutely exceptional.

"They were three really good penalties, they all go in the corner. He saved them anyway.

"He came back from holiday and was injured, it took a really long time to get him back to training and back to speed. But obviously he's ready now.

"He's a modern goalie, calm as you like, can play football and on top of that can catch balls and keep the ball out of the net in a really good manner. I'm over the moon for him."

Dominic Stricker defeated home favourite Lorenzo Musetti in five tie-break sets to make it two wins from two at the ATP Next Gen Finals and advance to the semi-finals.

The world number 111, who is seeded sixth in Milan following a flurry of withdrawals, defeated Musetti 4-3 (7-5) 4-3 (8-6) 3-4 (9-7) 3-4 (8-6) 4-3 (7-3) in Wednesday's epic match that last two hours and 31 minutes.

Having become the first player in the tournament's history to win three successive tie-breaks in Tuesday's win against Jack Draper, Stricker advances with a match to spare.

Musetti now faces a winner-takes-all showdown with Jack Draper on Thursday after the latter recovered to defeat Tseng Chun-hsin 1-4 4-2 4-3 (7-2) 4-2.

In the Green Group, Francesco Passaro saved three match points to overcome Italian compatriot Matteo Arnaldi 4-3 (9-7) 2-4 3-4 (7-4) 4-3 (7-4) 4-3 (10-8).

In what will go down as one of the all-time great matches in Next Gen history, Passaro triumphed after two hours and 38 minutes to get off the mark with his first victory.

"I am very tired," he said. "It was a really long match and this format I think it is tough and physical.

"For me it was physical today, with the tension as well, I was cramping. It was not easy. I am really happy to win and I will enjoy."

Brandon Nakashima moved to the top of the standings with a 4-1 4-3 (7-2) 4-2 victory against Jiri Lehecka as the third seed made it back-to-back wins at the Allianz Cloud.

Mexico were posed very few problems by Iraq in their first World Cup warm-up game, winning 4-0 in Girona on Wednesday.

Although many countries have been unable line up pre-tournament friendlies due to the awkward timing of Qatar 2022, El Tri will travel to the Middle East with two games under their belts.

Their first may not have been particularly competitive, but it did the job in providing an opportunity to build sharpness and confidence ahead of the tournament, with Mexico dominant throughout.

The first half was especially one-sided, but Tata Martino's men could only find the Iraq net once via Alexis Vega's simple finish following fine work by Jesus Gallardo at the end of a rapid counter.

Mexico's fortunes improved after the break, with Rogelio Funes Mori smashing into the roof of the net early in the second half, and it was 3-0 just past the hour – Gallardo unleashing an emphatic half-volley that gave the goalkeeper no chance.

The scoring was completed late on when a handball offence in the box led to a penalty, and Uriel Antuna coolly converted.

Mexico's second and final pre-World Cup game is against Sweden on Wednesday, with El Tri then set to face Poland, Argentina and Saudi Arabia in Group C.

Antonio Conte sympathised with his Tottenham players after they were eliminated from the EFL Cup by Nottingham Forest, citing tiredness in the run-up to the World Cup.

Despite playing 12 games since the beginning of October, Conte decided to make just four changes to the team that lost to Liverpool on Sunday, including starts for Eric Dier and Harry Kane, both ever presents this season.

The Italian blamed a lack of alternative options due to injuries as his team fell to a 2-0 loss at the City Ground thanks to goals from Renan Lodi and Jesse Lingard on Wednesday.

"The performance, I have to be honest, I think maybe tonight the energy was really poor for us" Spurs head coach Conte said.

"Don't forget that it was the 12th game in a really short period. The games that we played in the past, every game was really, really difficult and we lost a lot of mental energy and physical energy.

"I only say thanks to my players because there are players who are really tired. I have to manage the situation with [Pierre-Emile] Hojbjerg and [Rodrigo] Bentancur because they were tired.

"The same for Harry Kane. Until this morning we waited to see if he could start or not. He was the only [fit] striker so again, I can only say thanks to my players."

One positive for Spurs was that they did not go in behind at half-time, as they had done in their previous five games, but they also did not come out in the second half with much energy.

Lodi and Lingard's goals arrived in the first 12 minutes following the break, and even though Forest were reduced to 10 men when Orel Mangala was shown a second yellow card with 15 minutes remaining, Spurs could not find a response, having just two shots on target to the hosts' eight.

Debutant goalkeeper Fraser Forster made six saves to keep the score down, though Conte could at least call on the returning Richarlison from the bench, just a day after he was named in Brazil's World Cup squad.

"I have a group of players who are first men, and then good players," he added. "Another could be selfish to think to himself 'in a week I have to play the World Cup.'

"Instead, Harry Kane showed to be a really good man. Not only him though, the same for Bentancur, Perisic, and Dier is another player who has played a lot of games.

"We faced a situation that is really bad with the injuries. We arrived at the end in real difficulty. Now we have to try to rest and find energy."

Simone Inzaghi apologised for Derby d'Italia defeat to Juventus but insisted he welcomes pressure after Inter responded with a resounding victory over Bologna on Wednesday.

Inter were under scrutiny heading to San Siro after a 2-0 reverse in Turin on Sunday and fell behind to Bologna after Charalampos Lykogiannis's fortuitous 22nd-minute opener.

But the reigning Serie A champions bounced back in style, with Federico DiMarco scoring a brace along with goals for Edin Dzeko, Lautaro Martinez, Hakan Calhanoglu and Robin Gosens in a 6-1 win.

A dominant performance saw Inter climb into the top four and move within three points of second-placed Milan, with Inzaghi suggesting the pressure that followed the defeat to Juventus does not affect him.

"I was very sorry for Sunday's defeat. I have always had pressure since I played, and then as a coach," the Inter boss told DAZN after the game. 

"There is an excellent relationship with the management, we always talk to each other in victories and defeats.

"What pleases me is that, in victories and defeats, I have a management – and I am speaking of the directors [Beppe] Marotta, [Piero] Ausilio, and [Dario] Baccin – that are very transparent.

"I like them – they are direct and if they need to tell you something, they say it clearly. I have an excellent relationship with them."

Kristjan Asllani and Roberto Gagliardini both played important roles as substitutes in the absence of the injured Marcelo Brozovic and Romelu Lukaku, with Inzaghi highlighting the importance of squad depth.

"It's never easy for us coaches. We make choices every day. We played 20 games, 18 without Lukaku and 14 without Brozovic, two very important players for us," he said. 

"We have missed them but thanks to everyone we have made an amazing path in the Champions League.

"In the league we have lost some points that hurt us but now we have to transfer what we do at San Siro to the games away from home."

Inter visit Atalanta on Sunday for their final Serie A match before the World Cup break as they aim to cut the gap on leaders Napoli, who they trail by 11 points.

Kalvin Phillips is optimistic of earning a place in England's World Cup squad after making his return to action, but accepts "anything can happen" due to his lack of playing time.

The midfielder has endured an injury-plagued time of things since joining Manchester City from Leeds United in the close season, featuring in just four of his side's 21 matches.

However, after a two-month spell on the sidelines with a shoulder injury, Phillips made his comeback as a substitute in Wednesday's 2-0 EFL Cup third-round win over Chelsea.

That 40-minute cameo came on the eve of Gareth Southgate naming his 26-man squad for Qatar 2022, and Phillips is hoping he has done enough to have earned a place.

"Anything can happen. I'm optimistic but I know with the amount of game time I've had there's always a doubt," he told Sky Sports when asked if he believes he will be included.

"I think with my injuries I've not been playing 100 per cent because of my shoulder. Now it's sorted I can get back to what I was before. Hopefully it'll put me in good stead."

Phillips has yet to start a game since arriving in a £45million deal, with his appearance against Chelsea his first of any sort since facing Borussia Dortmund on September 14.

The 26-year-old, who has 23 caps for England, admits he felt nervous when replacing Rodrigo early in the second period at the Etihad Stadium.

"It's an amazing feeling. It's been a long time. I'm glad to get back out there and play with the lads," he said.

"But without playing for a while, it's nerve-racking stepping onto the pitch for one of my first appearances for the club. It felt good.

"[It's been] difficult. When I first found out I needed the operation everything went out the window. I didn't feel great about the situation. 

"But after a couple of days I always made sure I worked hard. I was always positive. I'm back fit now so hopefully have a chance.

"A couple of days after the operation my thought was to get back and do as much as I could to get fit. I did more sessions than I would have done to get my fitness back."

Man City host Brentford in the Premier League on Saturday in their final match ahead of the World Cup, which begins for England on November 21 with a clash against Iran.

Asked if he believes Phillips is ready to play a part in the tournament, City boss Pep Guardiola said: "There's a lot of days to go until the first game. He's ready."

Mikel Arteta insisted Arsenal's performance against Brighton and Hove Albion in the EFL Cup did not warrant defeat as he bemoaned their failures in front of goal.

The Gunners were eliminated from the third round of the EFL Cup for just the second time in their last 20 appearances after Brighton responded to Eddie Nketiah's opener with three unanswered goals.

Danny Welbeck's penalty restored parity in the first half before strikes from Kaouro Mitoma and Tariq Lamptey sealed a 3-1 victory at Emirates Stadium, where Brighton have won three of their last four.

Despite a comfortable defeat to Roberto Di Zerbi's Seagulls on Wednesday, Arteta suggested the Premier League leaders did not deserve to lose for a first time at home in nine games.

"The view is that the result doesn't reflect what happened on the pitch, I think it's clear," the Arsenal manager said. 

"In moments where we were clearly on top of the game, we didn't take our opportunities."

Arsenal debutant Karl Hein, a 20-year-old Estonian who joined in 2018, was at fault for Brighton's equaliser as he slipped before rushing out to fell former Gunner Welbeck.

The striker converted his spot-kick to become the first player to score at Emirates Stadium with four different clubs (Manchester United, Arsenal, Watford and Brighton), though Arteta refused to blame Hein.

"I think he deserves the chance. He's the first goalkeeper for his national team and at his age that's not usual," the Spaniard added.

"If I have to play him tomorrow again I would. Errors are part of football."

Another fringe player to come under criticism was Fabio Vieira, who is yet to shine after his move from Porto last transfer window, but Arteta acknowledged the midfielder will take time to adjust.

"I think in front of goal he's been unlucky but every player needs time to adapt. I'm not worried at all," Arteta said.

Arsenal visit Wolves in their final Premier League outing before the World Cup break and will soon have to consider the January transfer window, where Arteta suggested his side could be active.

He added: "That's a window that is open and we'll have to discuss the opportunities that we have and be on the market for opportunities."

Atletico Madrid failed to win a fifth successive match as they were beaten 1-0 away to Mallorca in LaLiga on Wednesday.

Diego Simeone's side – who had lost two of their previous three games across all competitions – were unable to stop the rot as they offered little threat in what was their final league game before the World Cup break.

Mallorca talisman Vedat Muriqi was unsurprisingly the one to edge Mallorca in front early on, and that ultimately proved decisive.

An Alvaro Morata strike was ruled out shortly after, but it was by no means a prelude to legal Atletico goals as Los Colchoneros failed to make the most of their dominance of the ball.

Mallorca were good value for their 16th-minute opener, however scrappy it was.

After Jan Oblak spilled Antonio Sanchez's long-range effort, Antonio Raillo's follow-up was blocked into Jaume Costa's path and his scuffed low cross fortunately left Muriqi with an easy finish.

Atletico thought they had a swift response as Morata lifted a lovely finish over Predrag Rajkovic following Rodrigo de Paul's excellent throughball, only for the goal to be disallowed for offside.

The visitors showed more attacking purpose at the start of the second half, but Axel Witsel completely missed the ball when teed up inside the box in the 48th minute.

It was not until the 82nd minute that Atletico threatened again, with Morata failing to bundle over the line from close range, and a few moments later he saw a volley brilliantly saved by Rajkovic.

A much-changed Liverpool side needed penalties to overcome League One Derby County after a goalless 90 minutes ended with the holders securing their place in the fourth round.

Jurgen Klopp made 11 alterations from the weekend's victory at Tottenham, and Derby held their own despite the 43-place disparity in league position.

The Rams' resistance made it all the way to the final whistle, but Caoimhin Kelleher saved three Derby penalties to see the Reds through.

Liverpool's escape keeps one of their best chances of silverware this season alive, with the Reds already 15 points behind Premier League leaders Arsenal.

Chelsea's disappointing run of form continued as they were eliminated from the EFL Cup by Manchester City at the third-round stage with a 2-0 loss on Wednesday.

Both sides made seven changes to their line-ups for the heavyweight tussle at the Etihad Stadium and it was Chelsea who looked the brighter during the first half.

But after Christian Pulisic and youngster Lewis Hall spurned promising chances, quick-fire goals early in the second half from Riyad Mahrez and Julian Alvarez put City in control.

City, who introduced Kalvin Phillips for his first appearance since mid-September, saw out the win to mean an early exit for last season's beaten finalists Chelsea.

City were restricted largely to shots from range in a first half edged by Chelsea, who would have been ahead at the interval if not for some good goalkeeping and poor finishing.

Pulisic scuffed a shot at Stefan Ortega from close range and had another effort from further back saved, while the lively Hall was denied at the end of a good run.

Jack Grealish forced Edouard Mendy into a couple of saves early in the second half, shortly after Phillips' introduction, and City's period on top resulted in the breakthrough goal.

Mahrez was fouled by Trevoh Chalobah just outside the box and sent the subsequent free-kick over the Chelsea wall – with Kalidou Koulibaly failing to jump – and past Mendy.

The hosts doubled their lead five minutes later through Alvarez, who tapped in after Mendy could only push Mahrez's shot into the path of the Argentina international.

Ortega produced another fine stop to deny Hall, while Pulisic had a late goal ruled out for offside, but Pep Guardiola felt no need to turn to substitutes Kevin De Bruyne and Erling Haaland.
