Miami Dolphins head coach Mike McDaniel described Tua Tagovailoa's injury in Thursday's 27-15 loss to the Cincinnati Bengals as a "scary moment" but revealed he will be discharged from hospital with nothing more than a concussion.

Tagovailoa was stretchered off and taken to hospital after being sacked by nose tackle Josh Tupou, with the back of the Dolphins QB's head slamming into the ground with his arms appearing to seize immediately after the impact.

Play was halted for more than 10 minutes as medical staff attended to Tagovailoa, who remained on the ground with minimal movement. The entire Dolphins team gathered at midfield during the delay.

Miami initially said Tagovailoa had suffered "head and neck injuries" before being taken to hospital.  McDaniel confirmed after the game that Tagovailoa had been cleared of any neck or back damage but had been diagnosed with concussion, although he would be discharged from hospital and travel back to Florida with the team.

"It was a scary moment," McDaniel said. "He was evaluated for concussion and he's in the concussion protocols. He was at the hospital. I believe he's about to get discharged.

"That was an emotional moment that's not part of the deal that anyone signs up for, even though you know it's a possibility in football to have something that you have to get taken off on a stretcher.

"All of his teammates, myself, were all very concerned. The best news we could get is that everything has checked out and he didn’t have anything more serious than a concussion. He'll be flying back with us on the plane."

The incident came on a short turnaround after Tagovailoa had a concussion scare in Sunday's 21-19 win over the Buffalo Bills, appearing dazed before his knees buckled after a heavy hit. He passed protocols at half-time and was able to play the game out.

Tagovailoa was limited at practice this week, although the Dolphins said that was due to back and ankle problems, rather than any head knock or concussion.

The NFL Players' Association had initiated an investigation into the process around the decision to permit Tagovailoa to play on against the Bills and reiterated that during Thursday's game.

"Player health and safety is at the core of the union's mission," the NFLPA said in a statement on Twitter. "Our concern tonight is for Tua and we hope for a full and speedy recovery. Our investigation into the potential protocol violation is ongoing."

The incident left both sets of players and staff along with the crowd in attendance at Cincinnati's Paul Brown Stadium shocked and emotional. McDaniel admitted it was hard to carry on afterwards.

"I think a lot of people struggled," he said. "I know me personally, if I didn’t have a job to do for the organization and the rest of the players, and didn’t have that obligation in my mind, I would have tapped it.

"It's not something that's comfortable for anybody. It was not a situation that you want for any of your players or your team in general. It's scary stuff. I'm just glad it worked out."

Dolphins wide receiver Tyreek Hill reiterated that sentiment but insisted that the organization's main priority was player health.

"Our main concern as a team and as an organization is always safety and making sure Tua is feeling alright and he's straight," Hill said.

"That's scary. I know it's football and everyone is competitive, but for a moment inside the stadium I felt everyone's prayers, even the Bengals' side.

The Miami Dolphins' winning start to the season is over and quarterback Tua Tagovailoa was stretchered off in a scary incident during their 27-15 loss to the Cincinnati Bengals on Thursday.

Joe Burrow threw two touchdown passes for the Bengals who claimed back-to-back wins to improve to 2-2, but the game will be remembered for Tagovailoa's injury where he was stretchered off and rushed to hospital with "head and neck injuries".

Tagovailoa went down during an eventful second quarter, slamming the back of his head into the turf in a Josh Tupou sack, where he appeared to suffer a seizure upon the initial contact. The Dolphins QB copped a heavy hit in last week's win over the Buffalo Bills but cleared protocols to play on despite fears of a concussion.

Teddy Bridgewater stepped in for Tagovailoa, shoveling a pass for Chase Edmonds' touchdown on half-time to reduce the margin to 14-12 at half-time.

Jason Sanders converted his third field-goal attempt of the game to have Miami up 15-14 at the final change, but the Bengals did all the scoring in the fourth quarter with Evan McPherson slotting two field goals before Burrow found a wide-open Hayden Hurst for a late TD after Vonn Bell's second interception.

Earlier, Bengals running back Joe Mixon opened the scoring, before both sides traded touchdowns in the second quarter, with Burrow connecting with Tee Higgins for a 59-yard TD deep down the left side.

Burrow completed 20 of 31 attempts for 287 yards and two touchdowns with no interceptions, while Mixon had 24 carries for 61 yards. Higgins starred with 124 yards from seven receptions and Ja'Marr Chase made 81 from four receptions, including a Tyler Boyd 23-yard pass.

Tagovailoa made eight of 14 passes for 110 yards with one interception before being taken off, with Bridgewater completing 14 of 23 passes for 193 yards with one TD and an interception after stepping in. Wide receiver Tyreek Hill had 160 yards on 10 receptions.

Miami Dolphins quarterback Tua Tagovailoa has been rushed to hospital after suffering head and neck injuries in Thursday's game against the Cincinnati Bengals.

The Dolphins QB appeared seriously hurt in a scary incident after he was slung to the ground in a tackle from Josh Tupou with 5:46 remaining in the second quarter.

Tagovailoa seemed immediately dazed and awkwardly raised his hands with his fingers extended while on the ground.

There was a lengthy delay as medical staff attended to the 24-year-old who remained on his back on the ground with minimal movement before he was stretchered off the field. He was immediately taken by ambulance to a nearby hospital in Cincinnati.

The Dolphins confirmed he was out of the game with head and neck injuries and added: "Tagovailoa has been taken to a local hospital for further evaluation. He is conscious and has movement in all his extremities."

The incident comes after Tagovailoa was listed as "questionable" for the game due to back and ankle problems which limited his ability to practice this week.

Tagovailoa also took a heavy hit in last week's 21-19 win over the Buffalo Bills and stumbled to the ground in the aftermath, yet was cleared of concussion and permitted to play on.

Dolphins head coach Mike McDaniel had insisted that the proper concussion protocols were followed and that the QB was cleared by the team and the independent neurologist.

Davis Riley produced a bogey-free opening round to claim a share of the lead alongside Will Gordon after the opening day of the Sanderson Farms Championship on Thursday.

Mississippi-native Riley carded a six-under-par 66 including four birdies in his first seven holes to set the pace at the Country Club of Jackson.

Riley he also holed an 18-foot putt for birdie on the 17th, backing up his birdie on the 16th for a strong opening round.

Gordon, who was among the last to finish on the opening day, came in strong with three birdies in his final five holes. He sunk a 23-foot birdie putt on the ninth.

Seven players are tied at five-under, including tour rookie Brandon Matthews who finished his round with back-to-back birdies to card 67.

Matthews is tied with Andrew Putnam, Kevin Yu, Mark Hubbard, Thomas Detry, Trevor Cone and Christiaan Bezuidenhout, the latter fresh from his Presidents Cup debut.

Among the day's highlights were aces on the fourth hole to Brandon Wu, who is three-under-overall, and M.J. Daffue, who had just double bogeyed the par-five third hole.

Reigning champion Sam Burns carded a bogey-free two-under-par 70, while one of the pre-tournament favourites Denny McCarthy is a further stroke behind after birdieing his final two holes.

Sahith Theegala (one over), Russell Henley (two over) and J.T. Poston (four over) struggled on the opening day, with the latter carding four bogeys and one double bogey in the par-four 12th.

George Russell has described Alex Albon's decision to return for the Singapore Grand Prix as "audacious", praising the Williams driver's determination to feature in what he feels is Formula One's "toughest race".

Albon spent a night in intensive care earlier in September after suffering respiratory failure following treatment for appendicitis.

The 26-year-old was then replaced by Nyck de Vries for the Italian Grand Prix, but is set to return to the grid this weekend.

The Singapore race is the longest of the F1 season, while the humid conditions at the Marina Bay Street Circuit are expected to test drivers' stamina. 

Russell – whose move to Mercedes paved the way for Albon to assume his seat with Williams – has been impressed by his recovery, saying: "It's definitely audacious to come back for the toughest race of the season having only just recovered.

"But it just goes to show the sort of grit and determination he has. I was in contact with his family on the Saturday night because it was looking very scary at one point.

"But it's pretty impressive to see how he recovered so quickly. The human body is a scary thing.

"It just goes to show one minute everything is fine, and the next minute everything can change almost totally out of your control. It will be interesting to see how he gets on this weekend."

Asked about the difficult conditions drivers will face this weekend, Russell added: "It doesn't matter how much training you do, you will never be able to replicate what you go through on track.

"I have been training with at least three layers of clothes on every single gym session, every time I go out on the bike.

"It's pretty uncomfortable. It's quite impressive how difficult the body handles heat, even in the sauna for half an hour. That's what we will be experiencing in the car. And then there is the physical element and cognitive side of things."

Novak Djokovic cruised past Pablo Andujar to reach the quarter-finals of the Tel Aviv Open on Thursday, showing no signs of rustiness on his first Tour-level outing since July.

Djokovic had not featured in an ATP-level match since his final victory over Nick Kyrgios at Wimbledon, having been forced to miss the US Open due to his COVID-19 vaccination status.

But the Serbian needed little time to find his feet in Israel, winning the first seven games of the match and breaking the Spaniard's serve four times en route to a 6-0 6-3 victory.

Speaking on court afterwards, Djokovic said: "Fantastic atmosphere here tonight, thank you very much. I like the court, it's very intimate and it's very loud. 

"The crowd here is very passionate about the sport, about tennis and I'm really, really happy to be here and to perform here in front of you, so thank you for your support."

The 21-time grand slam winner will face Canada's Vasek Pospisil in the last eight after he beat home hopeful Edan Leshem 6-3 6-2.

Two of Djokovic's fellow seeds fared less well, however, with Diego Schwartzman and Botic van de Zandschulp both being ousted after three-set contests.

Third seed Schwartzman failed to capitalise on a third-set match point in his 6-3 2-6 7-6 (9-7) loss to Arthur Rinderknech, while Britain's Liam Broady teed up a clash with Marin Cilic by beating Van de Zandschulp 6-4 4-6 6-3.

The Sofia Open also saw a couple of seeds fall to surprise defeats on Thursday, although Jannik Sinner avoided any drama in his 6-3 6-4 win over Nuno Borges.

Sinner now has a perfect 10-0 record at the event, which he won in both 2020 and 2021, and will face Australia's Aleksandar Vukic for a place in the final four.

Holger Rune also progressed to the last eight, though he was forced to rally after losing the opener against Lorenzo Sonego, but Pablo Carreno Busta and Oscar Otte were both dumped out.

Second seed Carreno Busta fell to a 6-3 3-6 6-2 reverse against Switzerland's Marc-Andrea Huesler, who will face Poland's Kamil Majchrzak in the quarter-finals after he came back to beat Otte 4-6 6-2 6-4.

Tallinn Open top seed Anett Kontaveit kept her hopes of winning her home tournament alive with a 6-2 6-1 demolition of Tereza Martincova on Thursday.

The 26-year-old won five out of the final six games as she stormed to the first set, before securing her place in the quarter-finals with a superb second set in which she broke Martincova four times.

Fellow Estonian Kaia Kanepi is also through to the quarter-finals after a 7-5 7-5 victory over Ann Li.

The world number 32 found a crucial break with the opener tied at 5-5 as she took the first set, before breaking Li three times in the second to seal the win.

Eighth seed Shuai Zhang was dumped out by Donna Vekic in a 6-2 6-4 defeat, while fellow seed Jil Teichmann also saw her tournament ended as Ysaline Bonaventure beat her 7-6 (10-8) 6-3.

At the Parma Ladies Open, top seed Maria Sakkari came from a set down for the second consecutive match to overcome Maryna Zanevska and reach the semi-finals.

Zanevska sparked hopes for an upset as she broke the world number seven three times on her way to taking the opening set.

But Sakkari improved in the second to tie the match, before overcoming two breaks of serve from her Belgian opponent to win six of the last seven games and earn a 2-6 6-4 6-4 success.

Sakkari will face Danka Kovinic in the semi-finals, after the 27-year-old's 6-4 6-4 triumph over Italian Jasmine Paolini.

Irina-Camelia Begu's run of 12 consecutive wins on clay came to an end as she was defeated 6-2 7-6 (8-6) by Ana Bogdan in an all-Romanian clash. 

Bogdan's opponent in the final four will be Mayar Sherif, who beat American Lauren Davis 7-6 (7-2) 6-3.

Max Verstappen suggested he would have liked to see Ferrari take the Formula One title fight to the wire ahead of his first opportunity to seal consecutive championships.

Verstappen could retain the drivers' championship at Sunday's Singapore Grand Prix, although it appears an unlikely prospect as he requires both Sergio Perez and Charles Leclerc to post poor finishes.

Nevertheless, it appears to be a matter of time before Verstappen clinches his second crown, with Ferrari's issues with reliability and strategy costing Leclerc the chance to compete.

Verstappen holds a 119-point lead over Leclerc at the top of the standings after winning each of the last five races, and the Dutchman says he would have relished a closer battle.

"I mean, [there are] two sides. Yes, in one way, I would have liked them to still be in the fight," he said on Thursday. 

"But from my side, of course it's also nice to win it in a more calm way. 

"I think what is good to see is that they are very competitive this year compared to the last few years, and I think that's what F1 needed."

Meanwhile, Verstappen is not getting carried away by the prospect of wrapping up the title in Singapore, and has revealed he would prefer to seal the deal at next week's Japanese Grand Prix.

"It's a bit unrealistic for it to happen. So I don't really think about it," Verstappen added. "It's quite a long shot. I just want to enjoy the weekend, and of course, try to win it.

"I think Japan is nicer. I'm really excited to go back there, It's been a while. It's an amazing track and for me, anyway, it has quite special memories.

"The first time I drove an F1 car was there in FP1, and I will always remember that. And besides that, it is kind of a home GP with [Red Bull engine provider] Honda.

"I think [it will be] my first proper opportunity to win the title. So yeah, of course, I'm looking forward to Singapore right now. But I'm also very excited for next weekend."

The PGA Tour has accused the LIV Golf Invitational Series of making "astronomical" offers to players in a bid to "sportswash" Saudi Arabia's global image in a lawsuit filed on Wednesday. 

The controversial LIV series – which counts the likes of Phil Mickelson, Sergio Garcia and Bryson DeChambeau among its ranks – launched an antitrust lawsuit against the PGA Tour last month.

LIV accused the PGA of operating as a monopoly and alleged the Tour's decision to issue suspensions to players who joined the breakaway circuit was improper.

Eleven LIV golfers were originally named as plaintiffs in that claim, although eight – including Mickelson – have since withdrawn.

The PGA Tour has now hit back with legal action of its own, alleging: "A key component of LIV's strategy has been to intentionally induce Tour members to breach their Tour agreements and play in LIV events while seeking to maintain their Tour memberships and play in marquee Tour events, so LIV can free ride off the Tour and its platform."

The PGA's counterclaim goes on to accuse LIV of offering players "astronomical sums of money" in an attempt "to use the LIV Players and the game of golf to sportswash the recent history of Saudi atrocities."

In a widely publicised statement, LIV responded by saying: "The Tour has made these counterclaims in a transparent effort to divert attention from their anti-competitive conduct.

"We remain confident that the courts and the justice system will right these wrongs."

FedEx Cup champion Rory McIlroy – who has been a staunch critic of the LIV series – declared golf was "ripping itself apart" earlier on Thursday, as the bitter divide between the two circuits shows no signs of healing.

One day earlier, McIlroy called on LIV players to do more to foster a sense of reconciliation between the tours, declaring: "The ball is in their court".

Tyson Fury's co-promoter Frank Warren has accused Anthony Joshua's camp of radio silence, stating they have "bent over backwards" in pursuit of an agreement.

The saga surrounding the 'Battle of Britain' bout on December 3 rumbles on without an apparent conclusion, after Fury issued his rival a deadline of Monday to sign a contract before he walked away.

Joshua failed to do that, leading Fury to close the door on a bout, but he handed an olive branch to his compatriot once again on Thursday, though made it clear a verdict would need to be reached before the end of the day.

On AJ's side, Eddie Hearn has said he was 'baffled' by Fury's behaviour and dubbed the deadlines as 'unrealistic' but Fury's camp have a contrasting view, claiming they are not getting any responses.

"We've done all that's necessary with BT, ESPN and DAZN. They're all happy. We gave them a contract. They've had it for two weeks and it hasn't come back yet," he told TalkSport.

"Ticketing and the venue is ready to go. We've agreed transparency with them. Everything in the pot. Everything they needed, co-promotion, the lot – we've bent over backwards. We've not had anything back.

"I had a bet with Tyson that we'd get it done in the next few days. He said 'no, Joshua doesn't want the fight'. I've lost the bet. Joshua said he wanted the fight, so let's get it done. I don't understand this."

Fury has consistently made it clear he will fight in December regardless of the opponent, having stepped back into contention after announcing his retirement after defeating Dillian Whyte at Wembley in April.

If a fight against Joshua does not materialise, Mahmoud Charr stands as the most likely opponent for Fury after he took to social media on Thursday to verbally accept a proposal to face the German.

"Mahmoud Charr, it seems now that AJ is finally out, he's ducked his way out, coward, and you're the man who wants to fight, so I like that," he said on an Instagram video.

"I like the fact you're very vocal and you're calling for a fight like a man should do. Any man who wants to fight a man should call him out as you've been doing to me. So I accept your challenge Mahmoud Charr, let's get it on."

Frenchman Romain Langasque leads the Alfred Dunhill Links Championship after producing an outstanding 11-under-par opening round of 61 on Thursday.

Langasque – who is 272nd in the official world golf rankings – hit two eagles, eight birdies and just one bogey in his round, equalling the best-ever at The Old Course at St Andrews made by Ross Fisher in 2017.

However, he sits just one clear of compatriot Frederic Lacroix, who went round in 62 at Kingsbarns.

It was a good day for the French as Antoine Rozner looked to have locked out the top three for them, before Dane Niklas Noergaard Moeller also carded an opening round of 63.

"It feels very good," Langasque said of his achievement. "As I said to my caddie, it didn't feel like I shot 11 under today. I was having a good run, but just five, six was the way I think of it, but just the end of the course was amazing.

"I holed a few long putts. The game was great but it didn't feel [like] I shot 11 under.

"I never [thought] I'd have the course record at St Andrews, now I think my name is on this board so I am really happy about this. It's only the first round so I want to stay really focused for the next few days."

Rory McIlroy could not match those numbers at Carnoustie, hitting six birdies and two bogeys as he finished with 68, but the world number two was pleased enough with his first round.

"I started really well," he said. "I played the back nine very well, then sort of stalled a little bit and made a couple of bad swings coming in. Overall, you are not going to get Carnoustie in easier conditions so I feel like I left a few shots out there.

"It was a decent day and to play decent, you do not want to be chasing in what looks like really bad weather tomorrow so I've put a red number on the board and have a few shots to play with."

Daniel Ricciardo has described the prospect of taking a Formula One reserve role in 2023 as "realistic" ahead of his McLaren exit.

Ricciardo has been linked with vacant seats at several teams since McLaren announced an early termination of his contract in August, with spots at Alpine, Williams and Haas up for grabs.

The Australian has struggled for consistency this year, and sits 14th in the drivers' championship standings after finishing just four of his 16 races in the top 10.

Ricciardo has also been linked with reserve roles at F1 heavyweights Red Bull and Mercedes, and recently said his desire to "get back to winning" will be a key consideration when he makes a decision on his future.

Speaking ahead of Sunday's Singapore Grand Prix, Ricciardo said his preference remained a permanent spot on the grid, but refused to rule out taking a back-up role.  

"Let's say my head space is in the same space," he said on Thursday. "I'm still keen to be part of F1 and of course, plan A would be to be on the grid.

"So nothing's changed but I don't want to just jump at the first kind of seat available. 

"I know the landscape probably changes as well at the end of next year, with contracts and whatever, so I don't want to say I'm remaining patient, but remaining open."

Asked about the prospect of taking a reserve role, Ricciardo added: "It's certainly something that's realistic, yeah.

"That's the two realistic options. It's not to be anywhere else. I love other disciplines of motorsport but I don't see myself there. 

"I feel as well if I jump into something like that, it closes the door on F1. It kind of feels like I've checked out, and I haven't. So I'm solely focused on F1.

"My team is talking with, I want to say, pretty much everyone, or they're having conversations, so we're just trying to put it all together and figure out what makes the most sense.

"So it's not that they're not calling or they're not interested, I'm not coming from a place of overconfidence, but we're just doing our due diligence and figuring out what's best.

"I'm trying to see beyond next year. Of course, I want to be racing but I also don't want to just look at the next 12 months and not look at the next 24.

"I guess I don't want to just race to race, I want to race with a true belief or understanding that I could be back on the podium, ultimately."

UFC chief Dana White has pushed back on suggestions this week's UFC media and fan blackout is due to Facebook founder Mark Zuckerberg as "total bulls***."

This weekend's Fight Night encounter between Mackenzie Dern and Yan Xiaonan will be closed to in-person attendance and coverage at the UFC Apex in Nevada.

Speaking at the event's media day, the former stated that attendance was a no-show as Zuckerberg had asked to rent the full venue for the event.

But White has now sought to shut down the claims, stating that the businessman, now chief executive officer and chairman of Meta, has not requested any such thing

"Mark Zuckerberg did NOT rent out the UFC Apex," he wrote on a post to social media. "That’s total bulls***."

Dern is looking for a 13th career victory in 15 bouts after bouncing back to winning ways with a split decision triumph over Tecia Torres in April.
