Newcastle United have signed Loris Karius to a short-term contract after back-up goalkeeper Karl Darlow sustained an injury in training.

Eddie Howe's side were in a strong position in their goalkeeping department in the final days of the transfer window.

Nick Pope, signed from Burnley, had an immediate impact in the Newcastle starting XI, displacing Martin Dubravka to leave Darlow as third-choice.

However, Dubravka headed to Manchester United on loan, and Darlow was then injured after the window closed.

Newcastle have instead been forced to turn to the free agent market, with Karius released by Liverpool at the end of last season.

The former Germany youth international had not appeared for Liverpool since the 2017-18 Champions League final, in which he suffered a concussion and committed two awful errors that allowed Real Madrid to win 3-1.

Karius was subsequently replaced by Alisson, spending the next two seasons on loan at Besiktas and the following campaign with Union Berlin.

He joins Newcastle after a year back at Liverpool, where he was no longer considered part of Jurgen Klopp's first-team plans.

"I'm excited," Karius said upon signing a deal until January, which could be extended to the end of the season.

"It's a good opportunity for me and a great project to be part of. It didn't take me long to make a decision.

"Newcastle have a great coach and play really attractive football. I felt it was the right project for me and I'm excited to work with the coaches and my new team-mates."

Stephen Curry has revealed the Golden State Warriors discussed the possibility of re-signing Kevin Durant – a move their superstar point guard would have welcomed.

Durant appeared set to be on the move this offseason after requesting a trade away from the Brooklyn Nets.

The former NBA MVP joined the Nets after leaving the Warriors in 2019, where he had spent three seasons playing alongside Curry, reaching the Finals in each year and winning two titles and two Finals MVP awards.

Curry and Durant won 131 of the 168 regular season games they played together (78.0 per cent), so it was perhaps no surprise the idea of a reunion appealed to the Golden State stalwart.

Ultimately, the Nets announced they had "agreed to move forward with our partnership" with Durant, but Curry has detailed his thought-process as the saga played out.

In an interview with Rolling Stone, conducted in August for the October issue, Curry said: "There was a conversation internally amongst us about, 'If he was available, would you?'

"Every team has those conversations, and obviously in our situation, they're going to call me and ask me, 'How do you feel about it?'

"I was never hesitant. The idea of playing with KD and knowing who he is as a person, from our history in those three years, I think KD's a really good dude.

"I think he is misunderstood. I think he has had certain things happen in his life that hurt his ability to trust people around him, in a sense of making him feel safe at all times.

"So all of those things I understand, having played with him and gotten to know him. I love that dude.

"And if you said, 'Oh, KD's coming back, and we're going to play with him'... I had so much fun playing with him those three years, I'd be like, 'hell, yeah!'

"Then you have to think: what does that actually mean? What does it look like? You tell me I'm playing with [Warriors team-mates Andrew Wiggins, Jordan Poole and Draymond Green], I'm like, 'hell, yeah!'

"There's all types of emotion and things that happen to the league. And if anybody's saying that you wouldn't entertain that conversation... no disrespect to anybody on our team, but you don't know how things work.

"But you also understand, if we run this thing back, I've got complete confidence in my team that we can win it again, as constructed.

"So, all those things were true. And it started with me wanting to play with KD at the beginning.

"Yeah, it's about winning, it's about having fun, playing the game of basketball. And that was part of the reaction of, 'yeah, it'd be amazing'... what does that actually mean?"

Williams driver Alex Albon suffered complications following surgery for appendicitis that led to respiratory failure and intensive care, but he is expected to return home on Tuesday.

It was announced on Saturday that Albon would not race in the Italian Grand Prix at Monza having been transferred to hospital, with Nyck de Vries deputising in his place and finishing ninth to secure points in his first ever F1 race.

Albon is expected to return to for the next round of racing in Singapore, but a statement issued by Williams on Monday detailed complications that arose after the 26-year-old's surgery.

"Further to Alex Albon's diagnosis of appendicitis on the morning of Saturday 10 September, he was admitted to San Gerardo hospital for treatment. He underwent a successful laparoscopic surgery on Saturday lunchtime," the statement said.

"Following surgery, Alex suffered with unexpected post-operative anaesthetic complications which led to respiratory failure, a known but uncommon complication. He was re-intubated and transferred to intensive care for support.

"He made excellent progress overnight and was able to be removed from mechanical ventilation yesterday morning. He has now been transferred to a general ward and is expected to return home tomorrow. There were no other complications.

"Alex's full focus is on recovery and preparation ahead of the Singapore Grand Prix later this month."

Aaron Rodgers urged patience with the Green Bay Packers' young wide receiver group after rookie Christian Watson's early drop of a would-be touchdown proved costly against the Minnesota Vikings.

The Packers, playing their first regular-season game since trading All-Pro wide receiver Davante Adams to the Las Vegas Raiders in the offseason, averaged just 5.3 yards per pass in a listless 23-7 defeat to the Vikings in Week 1.

Green Bay would have put up more points if not for a loss of concentration from second-round pick Watson, who beat veteran Patrick Peterson on a downfield route but let a perfectly placed deep ball from Rodgers slip through his fingers on the Packers' first offensive play of the game.

That would have tied the game at 7-7 in the first quarter, and the Packers did not find the endzone until the third, by which point they were in a 20-0 hole.

Rodgers looked visibly exasperated after the Watson drop and cut a frustrated figure during the loss. 

However, he accepts that such moments are going to be part of the process of replacing Adams in part with two rookies in Watson and fourth-round pick Romeo Doubs.

"He [Watson] knew there was gonna be growing pains, this is the real football, it counts, it's different, there's nerves," Rodgers said. 

"I thought Christian ran a great route to start the game. We talked about it during the week, 'Do you really want to start off with a bomb shot?'

"I said, 'Yeah what the hell? Why not? This kid can really fly, let's give him a chance', we've got to make those plays.

"We've got to have patience with those guys, they're young, they haven't been in the fire.

"That patience will be thinner as the season goes on but the expectation will be high, so we'll keep them accountable but it's gonna happen, there's gonna be drops, hate to see it on the first play but there's gonna be drops throughout the season.

"We had a lot of chances today. Not taking anything away from [the Vikings'] defense, but we hurt ourselves many times, myself included. I had a lot of opportunities to score a lot more than seven.

"[We] made a lot of mistakes in the perimeter, missed some throws, so there's a lot to clean up all the way around."

The Packers will look to bounce back in Week 2 when they have a second straight divisional game, this time at home to the Chicago Bears.

Victory at Flushing Meadows on Sunday night saw Carlos Alcaraz anointed both the US Open champion and the new world number one.

The victor of the New York final between Alcaraz and Casper Ruud would climb to the top of the ATP rankings, and a four-set success for the 19-year-old made him the youngest ever men's number one.

That record had previously belonged to a 20-year-old Lleyton Hewitt in November 2000.

Although Alcaraz's huge potential has long been public knowledge, the chances of him beating Hewitt's mark still seemed remote when he started 2022 ranked 32nd.

Even Juan Carlos Ferrero, the Spaniard's coach, did not anticipate a major breakthrough this soon, telling reporters after Sunday's win: "Of course, it comes very fast.

"It's a surprise for everybody except maybe to me, because I trained with him every day and I know [how] he's able to play on the court, [but] I was pretty sure that maybe it wasn't this year; it could be the next one."

By the time he took to Arthur Ashe Stadium against Ruud, however, Alcaraz's ascent to the top of the sport was a surprise to nobody.

Moving from number four to first place might have tied the biggest leap to number one in rankings history, but Alcaraz leads the ATP Tour in both match wins (51) and titles (five) in 2022.

There is little prospect of him slowing now, having become the first man in the Open Era to win the US Open title as early as in his second entry; the last to do so in any era was Pancho Gonzales back in 1948.

"Of course, I'm hungry for more," Alcaraz said afterwards. "I want to be in the top for many, many weeks. Hopefully many years.

"I'm going to work hard again after this week, this amazing two weeks. I'm going to fight to have more of this."

And Alcaraz will have to fight – Ferrero knows as much as that.

"The players now are going to play very motivated against him," the teenager's coach added. "Now he's number one. Before he was two or three.

"Even like this, it's like Real Madrid-Barcelona, there's a rivalry that gets you [to] increase your level. It's what is going to happen to him against his opponents. He has to be ready."

Since Roger Federer became the 23rd different men's number one in February 2004, the rankings have been dominated by the 'Big Three', with only Andy Murray and then, this year, Daniil Medvedev also leading the Tour in that time.

Now, as the 28th number one, Alcaraz – compared by Ruud to each of Federer, Rafael Nadal and Novak Djokovic – can set about securing his own long stay at the summit.

Aston Martin have signed F2 champion Felipe Drugovich as the first addition to their young driver programme.

The 22-year-old Brazilian won five races to clinch the F2 championship in 2022, where he was crowned winner in Monza, and signed his contract with the team on the same day.

Drugovich will take a spot as one of the team's reserve drivers in 2023, with Aston Martin planning for him to be involved in FP1 in Abu Dhabi at the end of the season as well as taking part in November's young driver test at the Yas Marina Circuit.

"Becoming a member of the AMF1 Driver Development Programme is a fantastic opportunity for me – and only adds to what has been an extremely enjoyable and successful 2022 season," Drugovich said.

"Winning in Formula 2 has long been regarded as the best possible launchpad into a career in Formula One, and I see my role at AMF1 as giving me all the tools to take that crucial next step.

"For me, 2023 will be a learning curve: I will be working with the F1 team, but my primary goal is to learn and develop as a driver. I hope that will give me an opportunity to race in Formula One in the future."

Drugovich's position with Aston Martin for 2023 effectively rules him out of the running for any vacancies on the grid, with a number of teams still yet to finalise their two drivers for next season.

Aston Martin may view Drugovich as the ideal successor to Fernando Alonso, who joins the team from Alpine for 2023 on a multi-year deal.

Julian Nagelsmann expressed his desire to see Robert Lewandowski receive a warm welcome on his Bayern Munich return, as he backed the striker to continue his fine start to life at Barcelona.

Lewandowski, who scored 238 Bundesliga goals during an eight-year spell with the Bavarian giants before heading to Camp Nou in July, has made a scintillating start to his Barcelona career. 

The Poland international has scored six goals in his first five outings in LaLiga, and turned on the style with a hat-trick in Barca's 5-1 Champions League thrashing of Viktoria Plzen last week.

Lewandowski will make a swift return to Munich with his new club for Tuesday's huge Champions League fixture, and despite the less-than-amicable nature of his departure, Nagelsmann believes he should be received warmly.

"If I see him before [the game] then I'm certainly going to give him my hand. I'm not sure if I'll see him beforehand, usually I don't," Nagelsmann said.

"I'm looking forward to our fans welcoming him back. When a player has been so strong for the team over the years, I think it's important. 

"He was an important part of the Bayern family. We had a personal exchange a couple of weeks back, not regarding football. I am looking forward to seeing him again."

Asked about Lewandowski's start to life in Spain, Nagelsmann added: "I think he can still continue to play at that level for a couple of years, I'm not sure how many goals he can score this season, I'm no genie. 

"I think it will be plenty. He has scored 40 plus usually, so I think he can do that in the Spanish league as well.

"I'm not sure if he's the most dangerous, but he's certainly one of their most dangerous players, the one that can score the most goals. They have great solutions there.

"Lewandowski always has great runs and positions inside the box. He's the most dangerous in front of goal, but if he doesn't get a lot of balls, it's difficult [for him]."

Having coached Lewandowski when he brought up a half-century of goals in all competitions last term, Nagelsmann is acutely aware of his talents, and believes Dayot Upamecano's past experiences of facing him could aid Bayern. 

"I have plenty of positions that I'm already pretty clear on," Nagelsmann added. "Upamecano has memories of playing against Lewandowski, back when he was at RB Leipzig. He knows him from our practice as well."

While Upamecano is set to start at the Allianz Arena, Leon Goretzka will not, as Nagelsmann looks to ease the midfielder in following his injury lay-off.

"The position next to Joshua [Kimmich] is going to be [Marcel] Sabitzer," Nagelsmann said. 

"I've had a chat with Leon, it was my decision to keep him on [against Stuttgart on Saturday]. We decided to keep him on for 94 minutes, that was a long time for him after the injury. He reacted well to it and is feeling good. 

"Him having to play from the start is not going to happen, we need him for the whole season and don't want to give him too many minutes at the start."

Meanwhile, Barcelona have suffered eight Champions League defeats to Bayern – twice as many as they have lost against any other opponent (4 vs Milan, Chelsea and Paris Saint-Germain).

Bayern also boast a 100 per cent record against the Blaugrana in the group stages and beat them twice in the competition last term, but Nagelsmann is keen to draw a line under those past meetings.

"We know Barcelona. They have a completely new mindset. You can delete the last few games against Barca from your memory, it's a whole different team, very aggressive," he said. "It reminds us of when Xavi still used to play himself. 

"In Gavi and Pedri they have great number eights that have great pressing actions as well. There's a great development there for the team, Xavi did a few things really well in the last weeks and months.

"They want to attack in a new way, and they're going to be very difficult opponents tomorrow."

Jurgen Klopp conceded Liverpool's 4-1 humbling at the hands of Napoli in the Champions League was their worst game since he took charge in 2015.

Liverpool were comprehensively beaten by the Serie A side in their opening game in Group A, the heaviest defeat by a Premier League side in their first game of a Champions League campaign since Arsenal lost 3-0 to Inter in 2003-04.

Speaking at a press conference ahead of their second group game at home to Ajax, Klopp did not hold back in his assessment of the "horror show" at the Stadio Diego Armando Maradona.

After Premier League games were postponed following the death of Her Majesty Queen Elizabeth II, Klopp also said his team would rather have played this weekend but "respected" the decision not to.

"Yes, we would have wanted to play," he said. "But for the reasons we all know it didn't happen and, of course, we respect that.

"Now we try to use the time for analysis and training, which made absolute sense after the game we played at Napoli.

"I have lots of thoughts [on the Napoli game]. I watched the game back plenty of times and it was a real horror show, to be honest.

"It was the worst game we played since I'm here. We've had a few bad games, I know that. Everyone remembers Aston Villa [7-2 loss in 2020-21] and some others where we were just not up to speed, but there were always glimpses in these games. In this particular game, [there was] nothing.

"You have to understand why that happens, it's not a common thing, that's more an individual thing. Eight out of 11 [players] were absolutely below their level, three others were not on top level, just [played] a normal game.

"In football it's like this, you sort all individual problems as a team, and that's the first thing we have to do, to follow a common idea again.

"Everything we did since I'm here and everything teams do in football is based on really solid, if not perfect, defending. That's what we had to work on, and that's what we did."

Liverpool have made an uninspiring start to the season, drawing three and losing one of their six Premier League games so far, and Klopp revealed there have been some home truths within the camp following the performance in Naples.

"I know that the players want to sort the situation, we are not over the moon about our season so far," he added. 

"In the end we all agreed that we could have conceded more goals in [the Napoli] game. We could have scored one or two more as well, but we could have conceded more, which is really crazy.

"We had absolute truth - didn't hide anything, we didn't hold back anything, there was no need for that... but not to knock the players down, just to make sure where we are now after this game, this is the starting point for us and now we have to make sure we sort the problems together on the pitch." 

Klopp confirmed that midfield duo Naby Keita and Alex Oxlade-Chamberlain – who were both left out of the Champions League squad – will not return from their respective injuries until October, despite the former being called up to the Guinea squad for the upcoming international break.

"No, I don't expect [Keita] to go on international duty," he said. "The return date is sometime in October, that's why we had to make the decision, with Ox it's the same, and that's why the two boys are not in the Champions League squad."

The Reds boss will also be without Andrew Robertson for the clash with Ajax, confirming the Scotland captain suffered an injury near the end of the Napoli defeat.

"Robbo is not 100 per cent," he said. "Very late, 93rd minute, he actually felt it the next day only, but he's out. I would say at least until after the international break."

UEFA has announced that the Europa League group stage clash between Arsenal and PSV on Thursday has been postponed.

The Gunners were due to host the Eredivisie side in their first home match of the competition, having beaten Zurich 2-1 last week, but the tie will not go ahead due to "issues related to ongoing events" following the passing of Queen Elizabeth II.

A statement read: "UEFA today announced that the UEFA Europa League tie between Arsenal FC and PSV Eindhoven, originally to be played on Thursday 15 September, has been postponed with a new date to be communicated in due course.

"This is due to the severe limitations on police resources and organisational issues related to the ongoing events surrounding the national mourning for Her Majesty Queen Elizabeth II."

It marks the second Arsenal game in a row to be postponed after all Premier League fixtures this past weekend were called off as a mark of respect to the monarch, who died at the age of 96 on Thursday.

Uncertainty remains around this weekend's fixtures, particularly those in the Premier League where Tottenham host Leicester City, Chelsea tackle Liverpool and Arsenal travel to Brentford.

If those games were to be postponed, Arsenal's next match would not be until the north London derby on October 1 due to the international break.

Tyreek Hill offered extremely colourful praise of Miami Dolphins head coach Mike McDaniel following their 20-7 Week 1 win over the New England Patriots.

The Dolphins delivered a performance to justify their offseason hype with a comfortable defeat of their AFC East rivals.

Miami held a 17-0 lead at half-time, with McDaniel making a decision that will likely increase his players' confidence in him late in the second quarter.

Leading 10-0 with the ball on the Patriots' 42-yard line on fourth down with seven yards to go, McDaniel - making his debut as a head coach - elected to go for it rather than punt the ball.

The move paid dividends, with Tua Tagovailoa hitting Jaylen Waddle on a slant route for a 42-yard touchdown to put the Dolphins in complete command.

And Hill, who arrived in a blockbuster trade with the Kansas City Chiefs in the offseason, found an interesting way to hail the bravery of his coach.

"He's going to need a wheelbarrow for his nuts to carry around," Hill said of McDaniel. "Because he's got a lot of cojones."

Waddle was more conventional in handing out plaudits for McDaniel, saying: "He's just got confidence in us. We're confident in him, every decision that he makes.”

Tagovailoa, who threw for 270 yards and a touchdown in an encouraging start to what many belive is a make-or-break year for the quarterback, added: "I love it. He has the utmost confidence in the entire offense. That's why."

Hill had eight catches for 94 yards in his Dolphins debut.

England captain Ben Stokes was proud of his team's attitude after seeing them secure a series win against South Africa at The Oval on Monday.

Starting the day needing just 33 runs with all 10 wickets remaining in their second innings, England took just 5.3 overs to reach their target of 130, sealing a 2-1 win in the three-Test series.

Alex Lees (39) was the only batsman to fall, trapped lbw by Kagiso Rabada, but his fellow opener Zak Crawley (69 not out) and Ollie Pope (11no) saw the hosts home.

It was England's sixth win in their last seven Test matches, and Stokes – who was named player of the series – outlined how pleased he was with the way the team has embraced the attacking mindset promoted by him and head coach Brendon McCullum.

"It has been a great series for us as a team," he told Sky Sports.

"It has been a series where we haven't had any real individual standout performances, but different people throughout the series have put their hands up in crucial periods for us.

"For me, it is about the clarity of the decisions. Me and Brendon are the guys who are sending this message to this group of players, I said to the lads in the dressing room the other day that the person who is delivering the message can only do so much."

Ollie Robinson returned during the series for the first time since an underwhelming Ashes series in January, and was named player of the match after claiming 7-89 with the ball across both South Africa innings, including five-for in the first.

"It has been a really enjoyable comeback for myself and the team," the bowler said to Sky Sports. 

"The experience over the last few weeks has been really enjoyable and it has just been great to be with the lads again. 

"It is nice to get where I am at the moment but I don't think I am the finished article by any means."

Wolves have signed Diego Costa on a free transfer after losing fellow striker Sasa Kalajdzic to an anterior cruciate ligament injury.

Kalajdzic, a £15.4million (€18m) arrival from Stuttgart in the recent transfer window, was substituted at half-time on his Premier League debut, a 1-0 win over Southampton at Molineux.

With the Austrian expected to miss the majority of the campaign, Wolves have turned to former Chelsea and Atletico Madrid striker Costa, whose contract will run until the end of the season.

Chairman Jeff Shi said: "We are absolutely delighted to welcome Diego Costa to Wolves, and back to the Premier League.

"A serial winner with a wealth of experience at the highest level, Diego will bring something unique to our dressing room and on the pitch, and we look forward to his impact at Molineux and Compton this season."

Costa, who has scored 10 goals in 24 senior appearances for Spain, won two Premier League titles during a successful three-year stint with Chelsea between 2014 and 2017.

Costa scored 52 goals in 89 Premier League appearances for Chelsea – during his three seasons as a Blues regular, only Harry Kane (75), Sergio Aguero (70), Romelu Lukaku and Alexis Sanchez (both 53) hit the net more often in the competition.  

Having been frozen out by then-Chelsea boss Antonio Conte in 2017, Costa returned to Atletico Madrid, for whom he had scored 64 goals in 135 appearances before moving to England.

The fiery 33-year-old then helped Atletico Mineiro to the Brazilian title in 2021. He departed as a free agent in January, paving the way for his arrival at Molineux, which remains subject to international clearance.
