Damar Hamlin's cardiac arrest is an important reminder for sports organisations and leagues to "reinvigorate their protocols" in order to react as quickly as possible for "life-saving opportunities".

The 24-year-old Buffalo Bills safety collapsed on the field during Monday's NFL clash against the Cincinnati Bengals, with the incident occurring during the first quarter at the Paycor Stadium.

Hamlin remained down for over 10 minutes as CPR was administered on the field, before he was loaded into a waiting ambulance and transferred to the University of Cincinnati medical facility. He has been described as being in a critical condition.

Speaking to Stats Perform, Dr Benjamin Abella MD, Professor of Emergency Medicine and Director at the Center for Resuscitation Science, said the NFL and organisers for the 2026 men's football World Cup, of which the USA is a co-host. will be constantly working on ways to improve reactions to medical emergencies on the field.

"There are important lessons for professional sports in all of this. We can also mention Grant Wahl, the journalist who died in Qatar recently. Now his situation may have been more complicated," he added.

"But in all of these cases, the presence of CPR-trained individuals, and importantly, the rapid availability of automated external defibrillators is crucial.

"With the World Cup coming to the US in some time, they will have to think very carefully about emergency action plans and the availability of AEDs. I think the NFL continues to address this and think about this, and rightfully so.

"It's quite a challenge when you have a massive venue if a cardiac arrest occurs in the stands, if it occurs on the field, how do you rapidly get a defibrillator and rescue team to the victim? It's not a simple problem.

"But it's something that sports leagues and sports venues need to constantly train for and reinvigorate their protocols for because life-saving opportunities are there. It's all a matter of the logistics and the timing of it."

Dr Abella explained the general public can also be educated on how to swiftly provide assistance when cardiac arrest occurs.

"Cardiac arrest is one of the most time-sensitive diseases in all of medicine, it turns out that the chance of surviving cardiac arrest falls by 10 to 15 per cent for every minute without CPR.

"So, it's a very dramatic and unfortunate condition that requires immediate action. This is especially important for the public to be aware of because everyone can do something, if they see someone collapse in cardiac arrest, they can provide CPR.

"The other key action is the use of an automated external defibrillator AED, which is now present in so many places, gyms, airports, train stations, restaurants.

"Through CPR and the use of AED, survival from cardiac arrest is not guaranteed, but the chance of survival is much improved."

Dr Abella detailed the key steps that will be taken in Hamlin's treatment.

"After initial recovery from cardiac arrest, where his heart is now beating, and he's moving blood, it's still a very tenuous, dangerous time for him," he said.

"In the days following cardiac arrest, there's a race to save the brain and improve organ function. A number of things are done in the hospital, generally in the ICU, and there are really three main things that will be taking place over the next few days.

"One is the use of a treatment modality known as targeted temperature management or TTM, which is an approach of carefully and precisely maintaining certain body temperatures for therapeutic gain. Generally, patients are cooled, and their body temperature is lowered modestly, which has actually been shown to improve brain recovery after cardiac arrest.

"Another key thing that almost certainly is being done is very, very careful management of blood pressure. If the blood pressure falls in a patient after cardiac arrest, and it tends to do so, this can be dangerous, because we need to maintain blood flow to the brain.

"So critical care physicians will be working carefully to monitor and manage his blood pressure with medicines and other things.

"The third important thing is going to be neurologic assessment. This is, I think, the part that's going to be hardest for all of us to watch because it generally takes two, three, four or five days, it takes a while. And we do this through recording of brainwaves, and also through imaging of the brain."

Tom Brady said the trauma being experienced by Damar Hamlin and the Buffalo Bills puts NFL careers into perspective.

Bills safety Hamlin suffered an on-field cardiac arrest during Monday's game against the Cincinnati Bengals and was said by a representative on Tuesday to be "fighting" to recover.

Hamlin has been described as being in a critical condition at the University of Cincinnati Medical Center, with team-mates and opponents calling for prayers for the 24-year-old's recovery.

The incident occurred when Hamlin made a tackle on Bengals receiver Tee Higgins in the first quarter, and after briefly returning to his feet, he slumped to the ground.

He was attended to on the field before being taken away by ambulance, with the game suspended while the Bengals were 7-3 ahead with 5:58 remaining in the first period.

Seven-time Super Bowl winner Brady, still playing as a 45-year-old with the Tampa Bay Buccaneers, said: "We're praying for Damar and his family this morning in Tampa. Moments like this put into perspective what it means to play this game we love."

The quarterback great added: "Thankful for our communities in Cincinnati and Buffalo for the overwhelming level of care and support I know they’ll continue to provide."

Jordon Rooney, a marketing representative for Hamlin, told Good Morning America on Tuesday: "I can't speak specifically on his medical condition. I will say that he's fighting, he's a fighter. The family is in good spirits. We're honestly just taking it minute by minute, hour by hour."

He later released a statement from Hamlin's family that said that they wanted "to express our sincere gratitude for the love and support showed to Damar during this challenging time".

"We are deeply moved by the prayers, kind words, and donations from fans around the country," the family added.

The family statement praised the first responders and medics "who have provided exceptional care to Damar", adding: "We feel so blessed to be part of the Buffalo Bills organisation and to have their support. We also want to thank coach [Zac] Taylor and the Bengals for everything they've done.

"Your generosity and compassion mean the world to us. Please keep Damar in your prayers. We will release updates as soon as we have them."

The NFL Referees Association (NFLRA) has commended the rapid response of medical staff who treated Damar Hamlin, and fully backed the suspension of the game between the Buffalo Bills and Cincinnati Bengals.

Hamlin collapsed on the field during Monday's game, with his team the Bills subsequently confirming the 24-year-old suffered a cardiac arrest.

He was given CPR on the field before being transported by ambulance to the University of Cincinnati Medical Center, where he is in a critical condition.

As stars from across the sporting world, particularly in the United States, offered their thoughts and prayers, the NFLRA lauded the swift action of the emergency responders at the Paycor Stadium.

"On behalf of the NFL officials working the Buffalo Bills vs. Cincinnati Bengals game last night we offer our thoughts and prayers for a speedy recovery for Damar Hamlin," a statement said.

"Additionally, we commend the emergency medical staff and doctors who quickly responded on the field to Damar's serious health issue."

The organisation also fully supported the decision to suspend the game.

"Like the players and coaches, our officials fully supported the suspension of this game as all attention needed to be focused on Damar's health," the statement concluded.

Damar Hamlin had the American sporting community rooting for him after the Buffalo Bills safety suffered an on-field cardiac arrest, as team-mate Josh Allen pleaded: "Please pray for our brother."

Hamlin was in a critical condition at the University of Cincinnati Medical Center, having collapsed during Monday's game against the Cincinnati Bengals.

Hamlin made a tackle on Bengals receiver Tee Higgins in the first quarter, and after briefly returning to his feet, he slumped to the ground.

He was administered CPR on the field, before being loaded into a waiting ambulance and rushed away.

Amid harrowing scenes, the game was suspended while the Bengals were leading 7-3 with 5:58 remaining in the first period.

Allen led the call for prayer for Hamlin, with well-wishers from across sport, entertainment and politics also sending thoughts and best wishes.

Former Chargers and Saints quarterback Drew Brees wrote on Twitter: "Damar Hamlin represents every one of us and every team-mate we've ever had.

"I've never met him, but I know him as a member of our brotherhood. My family and I pray for him and his family as he recovers. God be with him."

Michael Vick and Patrick Mahomes also said they were praying for Hamlin, the latter adding: "Please be okay man."

Tennessee Titans quarterback Ryan Tannehill added: "Praying for Damar Hamlin, his family and everyone in Buffalo... no words for a situation like this."

The NFL said: "Our thoughts and prayers are with Damar, his family and the Buffalo Bills."

Arizona Cardinals defensive end J.J. Watt said: "The game is not important. Damar Hamlin’s life is important. Please be ok. Please."

From basketball, the NBA said: "The entire NBA family's thoughts and prayers are with Damar Hamlin, his family and the NFL community."

That was reflected in post-game comments from a number of leading stars after Monday's NBA action, with Lakers superstar LeBron James saying: "My thoughts and super prayers goes up to the skies above for that kid's family, for him, for that brotherhood of the NFL and everybody a part of the NFL family."

James said it was "definitely the right call" to abandon the game for the night.

He said of the incident: "It was a terrible thing to see and I wish nothing but the best for that kid, for the city of Buffalo, for the franchise of the Bills and like I said, for the rest of the NFL as well and also the Bengals that was there and playing in that game."

Klay Thompson, from the Golden State Warriors, added: "As athletes, sometimes the game can overshadow us as individuals or people.

"On behalf of the organisation, we wish him the best. We're keeping him in our prayers and hoping for the best possible outcome. He's a tremendous person and it's bigger than the sport."

Hollywood actor Ben Stiller, a big sports fan, wrote: "Sending good thoughts and prayers to Damar Hamlin and his family."

Former New York City mayor Rudy Giuliani said: "Our prayers are with Damar Hamlin."

Amid the focus on Hamlin's plight, there was a surge in donations to a Christmas fundraiser the Bills star organised in 2020, to raise money to buy toys for children hit hard by the pandemic.

The fundraiser's target had been $2,500, but its running tally passed $3million by the early hours of Tuesday.

The Buffalo Bills announced 24-year-old safety Damar Hamlin suffered a cardiac arrest during Monday's game against the Cincinnati Bengals.

It occurred in the first quarter after Hamlin made a tackle on Bengals receiver Tee Higgins, and after briefly returning to his feet, he collapsed.

Hamlin remained down for over 10 minutes as he was administered CPR on the field, before being loaded into a waiting ambulance and rushed to a nearby hospital.

The Bills' statement read: "Damar Hamlin suffered a cardiac arrest following a hit in our game versus the Bengals. 

"His heartbeat was restored on the field and he was transferred to the UC Medical Center for further testing and treatment. He is currently sedated and listed in critical condition."

The game was suspended while the Bengals were leading 7-3 with 5:58 remaining in the first period.

Monday's fixture between the Buffalo Bills and the Cincinnati Bengals has been officially suspended after Bills safety Damar Hamlin collapsed on the field and was taken away in an ambulance.

Hamlin, 24, had made a tackle on Bengals receiver Tee Higgins, and after briefly returning to his feet, he collapsed.

He remained down for over 10 minutes, and was seen receiving CPR before being loaded into an ambulance and taken to a local hospital.

All players and team personnel returned to the locker room and over an hour passed before the NFL decided to officially call off the rest of the night's proceedings.

A statement from the league confirmed Hamlin is in "critical condition".

It read: "Tonight’s Buffalo Bills-Cincinnati Bengals game has been postponed after Buffalo Bills' Damar Hamlin collapsed, NFL Commissioner Roger Goodell announced.

"Hamlin received immediate medical attention on the field by team and independent medical staff and local paramedics. He was then transported to a local hospital where he is in critical condition.

"Our thoughts are with Damar and the Buffalo Bills. We will provide more information as it becomes available.

"The NFL has been in constant communication with the NFL Players Association which is in agreement with postponing the game."

The game was called off halfway through the first quarter with the Bengals leading 7-3.

Monday's game between the Buffalo Bills and the Cincinnati Bengals has been temporarily suspended after a scary situation unfolded as safety Damar Hamlin collapsed and was taken off the field in an ambulance.

The incident occurred during the first quarter, after Hamlin made a tackle on Bengals receiver Tee Higgins. He briefly returned to his feet, before collapsing.

He remained down for over 10 minutes as ESPN's broadcast reported he was receiving emergency CPR before being loaded onto a stretcher and into a waiting ambulance.

The game was temporarily suspended with the Bengals leading 7-3, with both teams heading back to the locker room as they anxiously await an update on Hamlin's health.

Tom Brady will not be rested for the Tampa Bay Buccaneers' final regular season game, with Todd Bowles vowing to field his starters.

Tampa Bay locked up the NFC South with a Week 17 win over the Carolina Panthers on Sunday at Raymond Jones Stadium, securing a top-four berth for the playoffs.

With nothing but a winning record to play for in Week 18 against the Atlanta Falcons, however, there had been questions as to whether the Bucs would choose to protect key players in an effective dead rubber.

Brady stated after victory he wanted to play against Atlanta, and now Bowles has revealed he intends to put his strongest line-up out rather than go the safe route.

"We can get better at a lot of things, so right now I'm planning on playing them," he said on Monday. "We'll see as the week goes forward.

"But we can get better at a lot of things that we need to work on, and we don't need to take our foot off the gas.

"You've got to weigh the pluses and minuses to that. So we'll see how the week goes, and we'll try to make some arrangements or corrections if we need to make them, and we'll go from there."

An 8-8 record this season means that a win against the Falcons can help the Bucs avoid the ignominy of a losing campaign heading into the postseason.

Bowles – who celebrated a second division title in a row with milk and cookies – is aware a third straight win will help the Bucs peak at the right time

"It'll boost morale," he added. "Winning helps, period, whether it's playoffs or regular season. You want to win every game you play.

"Obviously we had some tough ones we lost, we had some tough ones we won.

"But winning the last two the way we did, obviously that builds morale more, and you want to go in on a high note."

Art McNally, the first NFL official to be inducted into the Pro Football Hall of Fame, has died at the age of 97.

McNally spent 23 years as the NFL's director of officiating and was responsible for introducing the instant replay review process and formal training for officials.

He was enshrined in the Pro Football Hall of Fame last year and known as "the father of modern officiating", died of natural causes on Sunday, his family confirmed.

"Art McNally was an extraordinary man, the epitome of integrity and class," said NFL commissioner Roger Goodell. 

"Fittingly, he was the first game official enshrined in the Pro Football Hall of Fame in Canton, Ohio.

"But more importantly, he was a Hall of Fame person in absolutely every way."

The list of things that have not gone entirely to plan for the Tampa Bay Buccaneers is pretty extensive.

From offensive line injuries to an inconsistent pass rush and the questionable decision-making of head coach Todd Bowles in his first year in the job, the Buccaneers have had to deal with both misfortune and a host of self-inflicted problems.

Yet the most bemusing issue in what can at best be described as an up-and-down season for Tom Brady following his about-face on his initial offseason decision to retire has been his lack of a rapport with Mike Evans.

Sideline frustration between Brady and Evans has been a common theme for Tampa Bay in 2022, with the latter's struggles seeing him go 11 games without scoring a receiving touchdown.

That frustration was alleviated emphatically on Sunday as Evans exploded for a hat-trick of touchdowns in helping the Buccaneers overturn a 21-10 deficit against the Carolina Panthers and clinch the NFC South with a 30-24 victory at Raymond James Stadium.

Evans caught deep shots of 63, 57 and 30 yards from Brady as he destroyed an injury-hit Panthers secondary.

He created a burn, which is when a receiver wins his matchup on a play where he is targeted, on eight of his 12 targets in a performance that saw him rack up 207 receiving yards. Evans averaged 17.25 burn yards per target, trailing only Christian Watson and Davante Adams among wideouts with at least five targets in Week 17 as of Sunday.

It was belated reward for a season in which Evans, despite consistently appearing out of sync with Brady, he has excelled at getting open. Indeed, heading into Week 17, Evans led the NFL in combined open percentage (56.47) in matchups against man and zone coverage (min. 100 matchups).

His first deep touchdown reception saw Evans surpass 1,000 receiving yards for the season. It is his ninth successive 1,000-yard campaign, tying Tim Brown for the second-longest such streak in NFL history. Only San Francisco 49ers legend Jerry Rice (11) can claim to have more consecutive four-figure receiving seasons.

Evans' own record for the most successive 1,000-yard receiving seasons to start a career was also extended, but more important than his individual milestones is the confidence his treble could give both him and Brady as they prepare for the postseason.

The Buccaneers have had precious little on which to rely on the offensive side of the ball, save for their performance when going no-huddle and Brady's ability to lead comebacks in the fourth quarter.

Brady has a career-high five game-winning drives this season and four fourth-quarter comebacks, a tally that is one shy of his career-high in that respect.

But the rekindling of Brady's connection with Evans gives Tampa Bay something to lean on, a route to explosive plays that will be all the more critical in the postseason.

A narrow win over the Panthers won't do much to change perceptions that the Bucs are a team well short of being able to compete for a Super Bowl. However, Brady and Evans connecting consistently downfield improves the odds of them at least doing damage in the playoffs, especially in a possible first-round matchup with a volatile and vulnerable Dallas Cowboys secondary.

It's likely to be the final year of the Brady-Evans partnership in Tampa, one that has resulted in 32 touchdowns since the quarterback left the New England Patriots to head to the Buccaneers.

Though it remains a long shot that Brady's expected swansong with the Bucs will result in a second title in three seasons, his farewell may be extended a few weeks longer than many anticipated if he and Evans can deliver a few more demonstrations of the rapport that had previously made this offense so devastating.

In preparation for their biggest game of the season, the Tennessee Titans are once again turning to a player who has not even been on the team for two weeks to run the offense.

The Titans are staying with Joshua Dobbs at quarterback for Saturday's clash with the Jacksonville Jaguars in a game that will determine the winner of the AFC South.

Tennessee coach Mike Vrabel made the decision on Monday, four days after Dobbs made his first career start in a 27-13 loss to the Dallas Cowboys.

“I think he’s ready for the opportunity and looking forward to it,” Vrabel said.

Thursday’s defeat to the Cowboys marked the sixth straight loss for the Titans, dropping them to 7-9 and just behind the 8-8 Jacksonville Jaguars in the AFC South. The winner of Saturday’s matchup in Jacksonville will secure the division title and fourth seed in the AFC.

Dobbs didn’t do much to impress against the Cowboys, completing 20-of-39 passes for 232 yards with a touchdown and interception. However, he had just been signed off the Detroit Lions' practice squad eight days earlier, so the Titans considered it a good starting point.

"I think that there will be some things that we'll try to add or maybe things that we practiced last week that we didn't run,” Vrabel said. "I think it's just going to be good to have a full week and be able to have first and second down, third down, red zone emphasis — that's probably where him not having been here as much, I think we need to dive into his knowledge of the overall red zone and everything that's going on down there."

Dobbs, a fourth-round selection by the Pittsburgh Steelers in 2017, also showed more promise than rookie Malik Willis, who had taken over at quarterback after Ryan Tannehill was placed on injured reserve with an ankle injury.

Willis is 1-2 as a starter while throwing three interceptions without a TD pass. His 234 passing yards in his three starts are two more than Dobbs threw on Thursday.

Willis also had the luxury of playing alongside Derrick Henry in the backfield, while Dobbs played last Thursday without the two-time league rushing leader as he was inactive in Week 17 because of a hip injury.

Henry is slated to return for the winner-take-all matchup with the Jaguars.

A trio of Alabama superstars revealed they will be continuing their football careers in the NFL, as quarterback Bryce Young, edge rusher Will Anderson Jr. and running back Jahmyr Gibbs all announced on Monday they will forego their senior seasons and enter the draft.

Both Young and Anderson could be the number one pick, while Gibbs is considered one of the top running backs in the draft class and is projected to be selected in the first round.

The three made the decision to turn pro two days after Alabama cruised to a 45-20 win over Kansas State in the Sugar Bowl to cap an 11-2 season.

Young, the 2021 Heisman Trophy winner, threw for 321 yards and five touchdowns – an Alabama bowl record – in Saturday's rout to finish his career as one of the most prolific passers in school history.

In three years with the Crimson Tide, Young passed for 8,356 yards – second only to AJ McCarron's 9,019 yards – and 80 touchdowns – to trail only Tua Tagovailoa's school record of 87.

Anderson is a two-time unanimous All-American, a two-time SEC Defensive Player of the Year and a two-time winner of the Bronko Nagurski Trophy, which is awarded to the best defensive player in college football. He leaves Alabama with 34.5 sacks and 62 tackles for loss – second only to Derrick Thomas for the most in school history.

Gibbs played one season at Alabama after transferring from Georgia Tech and was named a second-team All-SEC performer in 2022 after rushing for 926 yards and seven touchdowns while adding another 444 receiving yards and three touchdown receptions.

Daniel Jones was left to bask in a "special moment" as he received a standing ovation at MetLife Stadium after helping the New York Giants clinch a playoff berth.

The Giants qualified for the postseason for the first time since 2016 with a dominant 38-10 win over the Indianapolis Colts on Sunday.

Jones has been much maligned since the Giants selected him with the sixth overall pick in the 2019 draft.

But he completed 79.2 per cent of his passes for 179 yards and two touchdowns and rushed for a further 91 yards and a touchdown as the Giants secured the sixth seed in the NFC.

Jones, in the final year of his Giants contract after they declined his fifth-year option, was removed from the game with seven minutes and 30 seconds remaining, receiving a tremendous reception from the crowd and from his team-mates on the sideline.

"That was a special moment," Jones said. "A lot of guys who've put in a lot of work. We've been through, certainly, some tougher times and it feels good to be on this side of it, for sure.

"Special moment with those guys. Really proud of this team, proud of what we did today. Grateful to be a part of it."

The Giants cannot improve their seeding and have nothing to play for in their Week 18 clash with the Philadelphia Eagles.

By contrast, the Eagles need to win to clinch the NFC East and the number one seed in the conference. Defeat for the Eagles would give the Dallas Cowboys the chance to snatch the division and both the Cowboys and the San Francisco 49ers the opportunity to clinch the one seed.

Giants head coach Brian Daboll indicated he would not rest his starters and give the Eagles some help in an unexpectedly nervy end to the season for Philadelphia, who suffered a second successive loss at home to the New Orleans Saints on Sunday.

"You get rest after the season. It's a long season," Daboll said. 

"This is the fun part of the season. It's the fun part of the season when you're winning. It's the bad part of the season when you're losing."

Patrick Mahomes added yet more achievements to his sparkling resume in the Kansas City Chiefs' narrow Week 17 win over the Denver Broncos.

The Chiefs were made to work much harder than expected for their 27-24 victory against a Broncos team playing their first game since firing head coach Nathaniel Hackett.

Mahomes threw for 328 yards, three touchdowns and an interception in helping the Chiefs come through a surprisingly tough test and improve to 13-3.

Those numbers took him to 5,000 passing yards and 40 passing touchdowns for the 2022 season, marking the second time he has surpassed those milestones in a single campaign.

He joined Tom Brady and Drew Brees as the third quarterback with multiple seasons with 5,000 or more passing yards, while only he and Brees have more than one season with 5,000 yards and 40-plus touchdowns.

Now on 5,048 passing yards, he will likely surpass the career-high total of 5,097 he set in 2018 when he won the MVP award in the regular-season finale against the Las Vegas Raiders on Sunday, in which the Chiefs could secure the number one seed for the AFC playoffs.

It would take a remarkable game, though, for Mahomes to better his career-high mark of 50 passing touchdowns, also set in 2018.

While the focus is on the Chiefs regaining a Lombardi Trophy they last won in the 2019 season, Mahomes understands the magnitude of his individual records.

"I mean, obviously it's really cool if you look at the names that are on that list," Mahomes said. 

"You're talking about the all-time greats with Drew Brees and Tom Brady, Peyton Manning, so just to be a part of the list that has those names on there, it's a special accomplishment.

"And I'm glad I have the people around me and the coaches around me to be able to do it."

Kyle Shanahan believes Brock Purdy having to come from behind to help the San Francisco 49ers to a 37-34 victory over the Las Vegas Raiders will be beneficial for the unbeaten rookie quarterback.

The 49ers were expected to brush aside the Raiders, for whom Jarrett Stidham was making his first NFL start at quarterback after they benched Derek Carr, but the anticipated blowout did not materialise.

Instead, the Niners were drawn into a compelling shootout, their league-best defense surrendering 500 yards to the Raider offense as Stidham delivering a stunning debut.

The 49ers trailed 24-14 in the third quarter but, even after overturning that deficit, were still forced into overtime despite Purdy delivering with the game on the line.

Having seen the defense quickly surrender a 34-27 advantage as the Raiders tied the game with 71 seconds remaining in regulation, Purdy gained 52 yards on four completions to wide receiver Brandon Aiyuk to put the Niners in range for a game-winning field goal, only for Robbie Gould to push his kick wide right.

A Tashaun Gipson interception in overtime gave Gould the chance for a reprieve, his 23-yard kick giving the 49ers a ninth straight win that saw them improve to 12-4 and move up to the second seed in the NFC playoffs. 

It marked the first time Purdy, who became the fourth rookie quarterback to win his first four starts since 1950, had dealt with playing from behind.

And Shanahan was delighted to see him come through the experience.

"I think that was great for him," said Shanahan. "We had to come from behind, especially there at the end. Also, he made a ton of plays today, but there's a number that he missed too.

"And that's the coolest part. There were some he'd love to have back. It was never one way too much or the other where he was struggling or doing well, but there were some mixed plays.

"To keep coming back and keep attacking, he never got gun-shy, made some real good decisions too and fought it out throughout the whole game and found a way to win."
