Star tight end Travis Kelce pulled down four touchdown catches to carry the Kansas City Chiefs to a 30-29 home win against the Las Vegas Raiders on Monday night.

Kelce became the first player in NFL history with four touchdown catches of fewer than 10 yards in a single game, finishing with just 25 yards from his seven catches as he was used heavily near the goal-line.

While it was the Chiefs who came out on top, it was the Raiders who started on fire, jumping out to a 17-0 lead one minute into the second quarter after Josh Jacobs' one-yard touchdown run followed a big 58-yard touchdown catch from Davante Adams, arguably the best receiver in the league.

Kelce would catch a one-yard touchdown in the second quarter, before securing a four-yard score and an eight-yard score on back-to-back drives in the third term. He would cap off his day with another one-yard touchdown in the fourth quarter to put his side up 30-23 with seven minutes remaining.

In response, Adams got on the end of his second deep touchdown of the game as he got behind the defense on a 48-yard bomb from Derek Carr, but instead of kicking the extra point to tie the game, they opted to go for two, and were stopped short.

That decision came back to haunt the Raiders, as they never got back into field goal range.

Chiefs quarterback Patrick Mahomes completed 29 of 43 passes for 292 yards and four touchdowns, while Carr completed 19 of 30 for 241 yards and two touchdowns. Neither quarterback committed a turnover.

Adams and Jacobs both had massive games for the Raiders, with Adams finishing with 124 yards and two touchdowns from just three catches, while Jacobs rushed 21 times for 154 yards and a score.

Tampa Bay Buccaneers' quarterback Tom Brady says he will "be all right" after appearing to injure his throwing arm in the 41-31 home loss to the Kansas City Chiefs.

Brady was strip-sacked by Chiefs safety L'Jarius Sneed in the second quarter, and the 45-year-old signal-caller immediately grabbed at his right arm before making his way to the sideline.

Despite the initial fears, Brady never missed a play and finished the match with season-highs of 385 yards and three touchdowns in defeat.

And Brady was not worried about his arm after the game, saying: "I'll be all right. It's football."

The Bucs' defeat to the Chiefs drops them to 2-2, though they remain atop the NFC South by virtue of their 1-0 record in divisional games.

They could surrender their position next Sunday though as the team second in the division, the 2-2 Atlanta Falcons, travel to face Brady's men at Raymond James Stadium.

Patrick Mahomes put on a masterclass with three touchdown passes as the Kansas City Chiefs improved to 3-1 with a 41-31 win over Tom Brady's Tampa Bay Buccaneers on Sunday.

Mahomes moved beyond 20,000 career passing yards, completing 23 of 37 attempts for 249 yards with three TDs, including an improvised flick for the second of Clyde Edwards-Helaire's TD.

The Chiefs blew away the Bucs early, scoring touchdowns from their opening two drives of the game including a Travis Kelce touchdown after 46 seconds following a Tampa Bay turnover.

Kansas City scored four touchdowns before half-time to lead 28-17 at the main break, representing the most combined points scored in the first half of a game this season.

Running back Edwards-Helaire had 19 carries for 92 yards with one touchdown, along with his one receiving TD, while Kelce made 92 yards from nine receptions with one TD. Kelce also moved past Rob Gronkowski into fifth overall for most career receiving yards for a tight end.

L'Jarius Sneed led the Chiefs' defensive display with eight tackles, including a sack on Brady leading to Noah Grey's one-yard rushing TD. Mahomes found Jody Fortson with 5:42 remaining in the third quarter for their fifth TD to make it 38-17.

Rachaad White and Leonard Fournette scored further TDs for the Bucs to limit the margin after wide receiver Mike Evans, who had eight receptions for 103 yards, scored their two first-half touchdowns.

Brady managed three touchdown passes, throwing for 385 yards on 39-of-52 passing, but the Bucs were always playing catchup after the Chiefs' early domination. The game marked only the fifth time in Brady's career he has scored 31 points and lost.

Week 4 of the NFL season could well have a substantial bearing on how the playoff race shakes out.

Through three weeks, the 2022 campaign has delivered excitement at almost every turn, and there are plenty of high-stakes matchups to whet the appetite this weekend.

There are conference championship and Super Bowl rematches on the docket, as well as extremely intriguing matchups between some of the season's early pacesetters.

But which of the games on the schedule are likely to deliver the best contests? Stats Perform can provide some insight in that regard, using its SmartRatings as a guide.

SmartRatings is an AI-based platform that provides excitement ratings for sporting events, teams and players. The excitement scale, ranging from 0-100, is powered by complex algorithms that are predicated upon six primary variables: pace, parity, novelty, momentum, context and social buzz.

The weight of each variable is dynamic and adapts as a season progresses. The excitement scale translates to the following general sub-ranges: 0-39 (Dull Game), 40-64 (OK Game), 65-84 (Good Game), 85-100 (Great Game).

So, let's take a look at the three games rated among the most exciting on the Week 4 slate and break down the key matchups that could decide them.

Buffalo Bills @ Baltimore Ravens

SmartRating: 67

Win probability: Buffalo Bills (55.3%)

Key Matchup: Lamar Jackson vs. Bills linebackers

The Bills only need to look to their AFC East rivals the New England Patriots for a reminder of what can happen when a defense fails to defend 2019 MVP Lamar Jackson effectively.

Last week, Jackson threw for 218 yards and four touchdowns with one interception while rushing for 107 yards and a touchdown on just 11 carries. He became the first player in Ravens history to throw at least three touchdown passes in each of the team's first three games of a season.

Limiting his efficiency on the ground will be critical for the Bills' hopes of outscoring a potent Ravens offense. On designed runs, Jackson is averaging a remarkable 13.47 yards per carry, with his threat as a runner naturally helping fuel the Ravens' play-action game. Baltimore's average of 10.85 yards per play on play-action is well above the league average of 9.15.

In Matt Milano and Tremaine Edmunds, the Bills possess two athletic and intelligent linebackers. They will need to display their physical gifts and their awareness to help limit Jackson's impact with ball in hand and ensure they do not bite too hard against play-action and open large throwing windows for him to attack. An evenly matched clash between two AFC heavyweights promises to be a classic, and Milano and Edmunds may have a crucial say in it tilting in the favour of Buffalo.

Kansas City Chiefs @ Tampa Bay Buccaneers

SmartRating: 75

Win Probability: Kansas City Chiefs (54.7%)

Key Matchup: Travis Kelce vs. Antoine Winfield Jr.

The Chiefs are unlikely to find much joy targeting the Buccaneers outside corners, Jamel Dean and Carlton Davis, who have each enjoyed excellent starts to the season as they look to gain a measure of revenge for their blowout loss to Tampa Bay in Super Bowl LV.

Instead, Patrick Mahomes will probably look to his most trusted weapon, All-Pro tight end Kelce, to help him get the Chiefs back on track following their shock loss to the Indianapolis Colts last weekend.

Kelce has run 24 routes from the slot this season compared to nine from his in-line tight end spot. Having consistently thrived in the 'power slot' role throughout his career, Kelce will hope to do significant damage from that position while going against one the premier young safeties in the league.

Winfield has spent 63 percent of his snaps this season in the slot but has conceded a burn, which is when a receiver wins his matchup on a play where he is targeted, on seven of his 11 targets. He has given up a big play on four of those targets.

With Kelce registering a burn on 18 of his 24 targets, the matchup looks to be in his favour. Winfield must find a way to ensure it isn't if the Bucs' defense is to provide yet more critical support to an offense that continues to struggle.

Los Angeles Rams @ San Francisco 49ers

SmartRating: 85

Win Probability: Los Angeles Rams 53.0%

Key Matchup: Aaron Donald vs. 49ers' Offensive Line

Even after losing their starting quarterback and All-Pro left tackle to injury, the 49ers are still only seen as slight underdogs in Monday's rematch of last year's NFC Championship Game.

But it is how the 49ers perform up front in the absence of Trent Williams that will likely determine if the Niners can continue their regular-season hoodoo over the Rams.

The Niners have won the last six regular-season meetings with Los Angeles, but the Rams – who finally knocked off their rivals in the game that mattered most – will be confident of ending that streak if Donald and Co. can take advantage of San Francisco sliding Colton McKivitz in at left tackle as Williams' replacement.

Much of that confidence will be based on how Jimmy Garoppolo performs when he is pressured. Among quarterbacks with at least 10 throws under pressure, Garoppolo's well-thrown percentage of 54.5 is the second worst in the NFL.

Donald has already racked up 13 pressures on 40 pass rush snaps and is known for his ability to create pressure from anywhere on the defensive line. McKivitz, right tackle Mike McGlinchey and an extremely inexperienced interior offensive line must deliver their best for San Francisco to avoid falling to 1-3.

Kansas City Chiefs quarterback Patrick Mahomes is unsure if he will be able to play at the age of 45, but said his aim is to replicate Tom Brady by playing at the highest level for as long as possible.

The Chiefs travel to Brady's Tampa Bay Buccaneers on Sunday, where Mahomes will come up against his legendary counterpart for the first time since the Bucs beat Kansas City at Super Bowl LV.

Both teams are 2-1 in 2022, and coming off Week 3 defeats after the Chiefs were beaten by the Indianapolis Colts, while Tampa Bay lost to the Green Bay Packers.

Brady is the NFL's all-time leader in passing yards (85,193) and touchdown passes (627), while he also led the league in passing yards (5,316) and TD passes (43) last season.

Speaking ahead of Sunday's clash at Raymond James Stadium, Mahomes said he wants to emulate the 45-year-old – who retired at the end of last season before changing his mind – by maintaining a high level for as long as possible.

"I want to play as long as I can play, and I can still have a chance to help the team get better," he said.

"Obviously, it's hard to play until you're 45 years old, and I don't want to be out there just hanging on. You see what Tom is – he's still playing at a very high level.

"I think that's why it's hard for him to kind of give it up – when you're playing at a high level you don't want to leave it.

"For me, I'm going to try to keep my body in the best shape possible and as long as they'll let me play and I can play at a high level, I'll be out there."

Mahomes was fourth in the league for passing yards in 2021 (4,839) and tied fourth for TD passes (37), and credited the impact Brady continues to have in the NFL.

"It's special to see the things that he's done in this league," the 27-year-old added. "The way he was able to change the position, the longevity of great success – I mean that's the crazy part – you look at his career and there's never really been a down year.

"He's always been great and had a great season and found ways to get even better.

"He's done stuff off the field that hasn't impacted him on the field, but still made his legacy even greater, so it's always a great opportunity for me and our team to go up against a great quarterback and really [see] where our team is at."

The NFL is hopeful Sunday's Kansas City Chiefs-Tampa Bay Buccaneers game can take place as scheduled at the latter's Raymond James Stadium, but a Hurricane Ian contingency plan is in place.

If the game needs to move for weather-related safety reasons, it will be relocated to the Minnesota Vikings' U.S. Bank Stadium.

NFL executive vice president of communications Jeff Miller told reporters on Wednesday of the league's plan B.

He said the NFL is in contact with local authorities regarding the category four storm, which has made landfall in southwestern Florida with damaging winds reaching 155mph.

The Bucs have already evacuated Tampa, training at the Miami Dolphins' facility while they are in Cincinnati to play the Bengals on Thursday.

"We're going to try to go about business as usual, and it's a little different, but everybody's families are safe, so hopefully we can concentrate," Tampa Bay coach Todd Bowles said.

In addition to monitoring the hurricane and any potential flooding or destruction around Raymond James Stadium, the league is taking into consideration whether playing the game in Tampa would exhaust resources that could potentially be needed in disaster relief efforts.

The league has not revealed a deadline as to when a decision would be made for the location of the game, but Miller said it will still be played on Sunday rather than being pushed back.

"Until we know more about the storm, it's going to be difficult to make that decision," Miller said.

This would be the second time in as many seasons the NFL has moved a game due to weather after Hurricane Ida forced the Green Bay Packers-New Orleans Saints 2021 season opener to be moved to Jacksonville.

The Saints are facing the Vikings in London this Sunday, making Minnesota's stadium available.

"We can't control the outside forces," Bowles said. "Our thoughts are with the city of Tampa right now, but where we have to play ... hopefully it is Tampa and everything is fine; that means we're not damaged too much.

"But if we have to go play elsewhere, we just have to focus and lock in. Nobody's going to feel sorry for us, so we've got to be ready to play."

Patrick Mahomes has taken responsibility for the Kansas City Chiefs' inconsistent start to the season on offense despite a largely new cast of receivers.

The Chiefs fell to 2-1 with Sunday's 20-17 defeat to the previously winless Indianapolis Colts.

After dominating the Arizona Cardinals in a 44-21 Week 1 victory, Kansas City had just 20 points on offense in their 27-24 win over the Los Angeles Chargers and came up short against the Colts.

Only three times in Mahomes' career have the Chiefs scored fewer than 17 points in a regular season game.

The superstar quarterback completed only 20 of his 35 pass attempts for 262 yards and a single touchdown, also throwing an interception on the team's final drive as they sought to force overtime.

After scoring TDs on their first two visits to the red zone, the Chiefs returned only three points from their final two, with Matt Ammendola's fourth-quarter field-goal miss proving costly.

This inefficiency might be explained by the absence of Tyreek Hill – traded to the 3-0 Miami Dolphins – but Mahomes is not looking for excuses.

"I don't expect any growing pains," he said. "Obviously we have new players and you don't know everybody's going to respond to tough situations.

"We've got to gel all together. It starts with me. There were certain throws I was putting on guys' back hips instead of in front of him. There were certain situations where we were just barely off of it.

"Whenever you're playing a tough game like that, you have to execute at a higher level and we have to learn from it.

"Our schedule gets no easier. We have a hard game Sunday [against] Tampa next week with a great defense, so we have to get better quickly.

"And if we don't, we don't want these [losses] to start piling up. We want to make sure we get back on that winning train."

For the season, only the Detroit Lions (11) have scored more red zone TDs than the Chiefs (nine from 13 RZ drives), who rank eighth in red zone TD efficiency.

Last year, the Chiefs were 14th in efficiency, scoring 41 touchdowns from 68 red zone drives.

The Miami Dolphins moved to 3-0 for the season and handed the Buffalo Bills their first defeat with a narrow 21-19 victory at Hard Rock Stadium on Sunday.

The Bills had lived up to their pre-season Super Bowl favourites tag after outscoring their opponents 72-17 in their first two outings, but they came unstuck in Florida.

Two touchdowns from Chase Edmonds propelled the Dolphins to a first win in eight against the Dolphins and gave them sole possession of top spot in the AFC East.

The Dolphins came out on top despite being outgained 497-212 in total yards, with Buffalo picking up 31 first downs to their opponents' 15.

Josh Allen has often been a menace against the Dolphins and completed a career-high 42 passes from 63 attempts for 400 yards and two touchdowns, but it was not enough for the Bills.

Miami took the lead with 10 minutes remaining through the second of Edmonds' touchdowns, and held on despite punter Thomas Morstead bizarrely kicking one into his own teammates' rear end and out of bounds for a safety.
 
Allen drove the Bills as far as Miami's 41-yard line on a completion to Isaiah McKenzie, but he was unable to get out of bounds and the clock struck zero before Allen could spike the ball for a potential game-winning field goal.

Jackson's five inspires Ravens

Lamar Jackson's five touchdowns inflicted a 37-26 loss on the New England Patriots and moved the Baltimore Ravens 2-1 in the AFC North.

Jackson became the first player in NFL history to register three-plus pass touchdowns and 100+ rushing yards twice in the same season, doing so in back-to-back games.

Mac Jones matched Jackson with a rushing touchdown and threw for 323 yards, but the Pats' offense ultimately self-destructed in a disappointing defeat at Gillette Stadium, with Jones limping off at the end to add insult to injury.

Mahomes interception proves costly

Rodney McLeod picked off Patrick Mahomes with eight seconds left for the latter's first interception of the season as the Indianapolis Colts beat the Kansas City Chiefs 20-17.

Mahomes finished the game 20 for 35 for 262 yards, one touchdown and that costly interception that saw the Chiefs fall to 2-1 for the year.

The Colts only took the lead with 24 seconds left in the fourth quarter as Matt Ryan and Jelani Woods hooked up for the second time with a 12-yard touchdown.

Two weeks down in the NFL and the action has been sensational so far.

Late comebacks were the name of the game last week and Week 3 promises to bring even more excitement.

Sunday sees the Buffalo Bills and the Miami Dolphins battle it out to remain undefeated, the Baltimore Ravens will aim to respond to a Week 2 defeat against the New England Patriots, while the Las Vegas Raiders and Tennessee Titans fight to pick up a first win of the season.

There's plenty more on the agenda and Stats Perform has used Opta data to preview the action.

Buffalo Bills (2-0) @ Miami Dolphins (2-0)

The Bills travel to Florida having won their past seven games against the Dolphins, outscoring them by better than a two-to-one margin (258-123). That marks Buffalo's longest winning streak against Miami, beating a run of six consecutive victories from 1987 to 1989.

Buffalo have outscored their opponents 72-17 so far this season to stand 2-0, with the +55-point differential their second-best through the first two games of a season. In 1981, they won their opening two matches by a combined score of 66-3 (+63 points).

The Dolphins overcame a 21-point fourth-quarter deficit (35-14) in last week's 42-39 win at Baltimore, marking the sixth time since 1925 that an NFL team has won a game in regulation time after trailing by such a margin in the fourth quarter. The last such comeback win was in 2010, when the Eagles beat the Giants 38-31 in Week 16, having trailed 31-10.

Tua Tagovailoa threw six touchdown passes, including four in the fourth quarter, against the Ravens last week. Since 2001, the only other player to throw four touchdown passes in the fourth quarter of an NFL game was Sage Rosenfels for the Texans against the Titans in Week 7 of the 2007 season, though Houston lost 38-36.

Baltimore Ravens (1-1) @ New England Patriots (1-1)

The Patriots have a 9-2 record against the Ravens in the regular season, the best record by any team against Baltimore in their history – though they have split four postseason matches.

Lamar Jackson became the first player in NFL history to have a 75+ yard passing touchdown and a 75+ rushing touchdown in the same game during last weekend's defeat to the Dolphins.

In week 2, the Patriots beat the Steelers 17-14. Since Bill Belichick became head coach in 2000, the Patriots are 42-23 in games decided by three of fewer points, the best such record in the NFL.

Nelson Agholor recorded 110 receiving yards in Week 2, becoming the first Patriot with a 100-yard game since Jakobi Meyers in Week 15, 2020. That brought an end to a 20-game streak without a 100-yard receiver for the Patriots, which was the longest spell in the Belichick era.

Las Vegas Raiders (0-2) @ Tennessee Titans (0-2)

The Raiders have won their past three games on the road against the Titans. The last time the Raiders won four straight road games against a single opponent was a six-game streak against the Chiefs from 2007 to 2012.

An 29-23 overtime loss to the Cardinals in Week 2 came despite them holding a 23-7 lead in the fourth quarter, marking the biggest fourth-quarter blown lead for a loss in franchise history.

The Titans are 0-2 for the first time since 2012 and last started a season 0-3 in 2009. The 41-7 loss to the Bills last week was the largest defeat suffered by the Titans under Mike Vrabel.

Both the Raiders and Titans are 0-2 this season after making the playoffs a season ago. Neither franchise has ever started a season with two defeats and rallied to make the playoffs, while the last NFL teams to do so being the Texans and Seahawks in 2018.

Elsewhere…

Chicago host the Texans with just 432 offensive yards to their name so far this season, the worst in the NFL and the fewest yards the Bears have gained in the opening two weeks of a campaign since they had 335 net yards at the same stage in 2003.

Patrick Mahomes rallied the Chiefs offence to a 27-24 victory against the Chargers last week, overcoming a 17-7 second-half deficit, and are eyeing a third-straight win this season against the Colts. Since his first NFL season (2018), the Chiefs have more comeback victories after trailing in the second half (17) than any other NFL side.

The Saints travel to Carolina on the back of a 20-10 home defeat to the Buccaneers last week. Dating back to last season, New Orleans have scored 17 or fewer points in five of their past nine games (1-4). When they have scored 18 or more, they stand at 4-0.

The Cincinnati Bengals have plenty to do offensively against the Jets, with Joe Burrow having been sacked 13 times so far this season and thrown four interceptions. The last QB to be sacked that many times while throwing as many picks in the opening two weeks of a season was Danny White of the Cowboys in 1987.

The NFL has suspended Kansas City Chiefs linebacker Willie Gay for four games for violating the league's personal conduct policy.

The suspension was revealed on Monday and stems from an arrest in January, when the 24-year-old was charged with misdemeanour criminal property damage at the home of the mother of his son.

He started in both of Kansas City's playoff games last January following the arrest, and agreed to a pre-trial diversion program over the summer to conclude the case.

Gay has started both games for the 2-0 Chiefs this season and is tied with L'Jarius Sneed for second on the team with 16 tackles. He also has two tackles for loss, two passes defended and one quarterback hit.

It is uncertain if Gay will appeal the suspension in an effort to get it reduced, but as it stands, he will miss games against the Indianapolis Colts, Tampa Bay Buccaneers, Las Vegas Raiders and Buffalo Bills, and will be eligible to return against the San Francisco 49ers in Week 7.

Patrick Mahomes just about got the better of Justin Herbert on Thursday but expects the Los Angeles Chargers to continue to push his Kansas City Chiefs all the way.

Both the Chiefs and the Chargers are tipped for Super Bowl contention this year in a highly talented AFC West.

Kansas City have won the division six years in a row, but the scale of their task this season was made clear in this meeting with the Chargers, who forced Mahomes to rally from a 17-7 deficit to win 27-24.

Herbert admirably battled a rib injury as he attempted to take down Mahomes, yet the former MVP delivered yet another comeback.

This was the 20th game of Mahomes' career – regular season or playoffs – in which he had been down by 10 points, and he has now converted 11 of those into wins.

Past turnarounds include the Super Bowl LIV success against the San Francisco 49ers when the Chiefs scored 21 unanswered points in the fourth quarter, as well as Herbert's NFL debut, when the Chargers lost in overtime early in the 2020 season.

"I think every game [against Herbert] is going to be a lot like this one," Mahomes told Amazon Prime Video.

"In the games I've played against him in the past, we've gone to overtime twice and it's been an end-of-game situation.

"It's going to be games like this, and hopefully I can find a ways to win them and our team can find a ways to win them, like we did today."

Mahomes is the only NFL quarterback with a winning record in games where he has trailed by double-digit points (minimum 20 starts), with Tom Brady next-best at 39-61 (.390).

"I want to go out there and win; I don't care how it looks," Mahomes added. "Tonight was very ugly.

"I'm sure it's not going to have a great film session tomorrow, but we found a way to get a win at the end of the day, and that's all I care about."

Los Angeles Chargers head coach Brandon Staley says they will learn more about the severity of quarterback Justin Herbert's apparent ribs injury on Friday but is confident he will be OK.

Herbert played through apparent pain in Thursday's 27-24 loss to the Kansas City Chiefs following a series of big tackles on the QB in the fourth quarter.

The Chargers QB still managed to find DeAndre Carter and then Josh Palmer in an impressive drive for a late touchdown but seemed in discomfort and gestured towards his ribs on the sidelines.

Herbert did not appear for post-game media duties, instead going off for an X-ray on the injury, although Staley was confident he would be fine.

"No," Staley told reporters when asked if he was concerned about Herbert's health. "No, because he's Justin Herbert."

Staley added: "You're not going to see a quarterback at any level of football play tougher and do more for their team and will their team to give them a chance more than him.

"There's nobody that can do what he can do, nobody. He showed a lot of guts, he showed us what he shows every day, that we're never out of the fight, and he brought us back and gave us a chance."

Despite that, Staley revealed they anticipate they will learn more about Herbert's health on Friday after a more thorough evaluation.

The Kansas City Chiefs fought back from another double-digit deficit sparked by rookie Jaylen Watson's 99-yard pick six as they won 27-24 over the Los Angeles Chargers on Thursday.

Patrick Mahomes produced a patient display, throwing two touchdowns and completing 24 of 35 passes for 235 yards, leading them back from a 17-7 deficit to make it two wins to start the new season.

Justin Herbert was gallant for the Chargers, playing through considerable pain after a series of fourth-quarter hits, to end with three TD passes, completing 33 of 48 passes for 334 yards but with one interception.

That interception came in the fourth quarter with scores locked at 17-17, with Herbert aiming for Gerald Everett on the goalline, only for Watson to clasp it and race away for the game-winning TD.

The Chargers had led 10-7 at half-time, with rookie Alexander Horvath making it two touchdowns in his first two games, before Mahomes' side-arm fastball found Jerick McKinnon for the reply, moving him past Alex Smith for the third-most completions (1,588) in franchise history in the process.

Mike Williams, who had eight receptions for 113 yards, plucked a remarkable one-handed catch under tight coverage from L'Jarius Sneed to put the Chargers up 17-7.

The Chargers were left frustrated after two interceptions were overturned before Mahomes found Travis Watson with a 41-yard pass to score. The Chiefs would pile on 20 unanswered points after rookie Watson made his pick six before Matt Ammendola converted a 32-yard attempt.

Herbert found DeAndre Carter with a late dart before showing poise under apparent duress from a fourth and goal to hit Josh Palmer to make it 27-24. The Chargers confirmed after the game that Herbert would undergo an X-ray.

Thursday night’s marquee matchup between the Los Angeles Chargers and Kansas City Chiefs features two potent offenses, but one team will be decidedly short-handed with decorated Chargers wide receiver Keenan Allen ruled out due to a hamstring injury.

Allen was forced to leave the Chargers’ Week 1 24-19 win over the Las Vegas Raiders in the first half after he had four receptions for 66 yards. Allen said he felt a slight pull, and the hamstring tightened after he planted his foot to the turf during the second quarter.

Coach Brandon Staley on Tuesday said Allen's injury ''is going to take some time''.

Without Allen, fellow receivers Mike Williams and Joshua Palmer figure to assume enlarged roles, with DeAndre Carter also likely to see increased playing time. Both Palmer and Carter had three catches against the Raiders.

Allen has been mostly durable during his 10-year career and has appeared in 16 games in four of the previous five seasons. The only significant time he missed was after he tore his ACL in the opening week of the 2016 season.

The 30-year-old Allen has caught at least 95 passes each of the past five years, tied for the second-longest streak in NFL history. He leads the league in catches over the past five seasons, where he has posted at least 1000 receiving yards in each and is a five-time Pro Bowl selection.

Patrick Mahomes and Saquon Barkley were recognised as the respective AFC and NFC Offensive Player of the Week after flying starts to the new NFL season.

Mahomes led the Kansas City Chiefs to a dominant 44-21 Week 1 win at the Arizona Cardinals.

The 2018 MVP leads the league in passing touchdowns (five), passing yards (360) and quarterback rating (144.2) at this early stage.

Only Joe Burrow matched Mahomes' 22 passes for first downs, while he did not throw an interception and was not sacked, making him an obvious choice as the standout player in the AFC.

Minkah Fitzpatrick, who played a vital role in the Pittsburgh Steelers' wild win over Burrow's Cincinnati Bengals, is the AFC Defensive Player of the Year.

The Steelers safety caught a pick-six from Burrow's first pass of the game and later, crucially, blocked Evan McPherson's PAT to take the game to overtime.

Cade York was more accurate as time expired in the Cleveland Browns' dramatic victory over the Carolina Panthers, kicking the winning field goal to earn AFC Special Teams Player of the Week recognition.

In the NFC, New York Giants running back Barkley was the standout player on offense, stealing the show against a Tennessee Titans team featuring two-time rushing yards and rushing TDs leader Derrick Henry.

Barkley has the most rushing yards at this early stage with 164 and a score. His 68-yard run in the drive that culminated in his TD was the longest carry of the week.

The fifth-year superstar, who has been hampered by injuries since an outstanding rookie season, also caught a Daniel Jones pass for the decisive two-point conversion in a 21-20 Giants victory.

Also honoured in the NFC were debutant Seattle Seahawks linebacker Uchenna Nwosu and Philadelphia Eagles cornerback Zech McPhearson.

Nwosu sacked the Denver Broncos' former Seattle quarterback Russell Wilson and forced a fumble from Melvin Gordon at the one-yard line, while McPhearson fielded the Detroit Lions' attempted onside kick to set up a Boston Scott touchdown in an Eagles win.
