Andy Reid said Patrick Mahomes was "feeling good" after the Kansas City Chiefs star suffered a concussion in Sunday's 22-17 win over the Cleveland Browns.

Mahomes was replaced by Chad Henne in the third quarter of the AFC Divisional Round game at Arrowhead Stadium on Sunday after a big hit from Browns linebacker Mack Wilson.

Amid concerns over the 2018 NFL MVP – who joined Hall of Famer Steve Young (1993-94) as the only players in NFL history to have a passing touchdown and rushing TD in three successive playoff games – Chiefs head coach Reid was upbeat about Mahomes' health.

"He's actually doing very well. I just talked to him and he's doing good," Reid told a news conference.

"We'll see how he is tomorrow, but right now he's feeling good."

Without Mahomes, Super Bowl champions the Chiefs still managed to book a meeting with the Buffalo Bills in the AFC Championship Game.

Henne produced a 13-yard run and made a short pass to Tyreek Hill on fourth-and-one to seal the Chiefs' win.

"When you're around him [Henne], you just know. I'm glad he had an opportunity to play a week or two ago, whenever our last game was, and get in," Reid said.

"I think that helped him when he jumped in this time of just being comfortable with the speed of everything. Everybody has full confidence in him."

Reid added: "We go through all of those Saturday night with the quarterbacks and those situations, fourth-and-one to win the game, what do you want? That play happened to be there.

"My coaches were on board between Mike [Kafka] and Eric [Bieniemy] and Joe [Bleymaier] upstairs, they all did a great job, with the spot, with the calls, with everything. They were spot on so it was a great job."

The Chiefs will host the AFC Championship Game for the third consecutive season. According to NFL Research, Kansas City joined the 2002-2004 Philadelphia Eagles – also coached by Reid – as the only teams to stage three straight conference championships.

Two separate Patrick Mahomes issues gave the Kansas City Chiefs serious cause for concern even as they beat the Cleveland Browns 22-17 to return to the AFC Championship Game.

The defending Super Bowl champions are now one win away from returning to the NFL's showpiece event but will spend the coming days worrying over superstar quarterback Mahomes' status after he exited this game with concussion, having already gone down with a toe injury.

Sunday's success proved far more testing than might have been expected as the Chiefs, led by Mahomes, got off to a typically dominant start, making the most of their full array of offensive weapons in a 10-play, 75-yard opening drive that ended with the QB running in from a yard.

The Browns were restricted to a field goal in response and Mahomes then found Travis Kelce - a boyhood Cleveland fan - for a second Kansas City score.

But Mahomes soon required treatment on his toe and the Chiefs' momentum waned, fortunate to stretch their lead through two field goals heading into halftime as a touchback cost the Browns, with Daniel Sorensen's hit - seemingly led with the helmet - forcing a fumble from Rashard Higgins through the end zone.

Even as Tyrann Mathieu picked off a Baker Mayfield pass at the start of the second half, Cleveland came again and the QB connected with Jarvis Landry for a first TD.

Mahomes was soon heading for the locker room after taking a big hit from Mack Wilson and struggling to regain his balance, with confirmation following that he would not return shortly before Kareem Hunt's three-yard run completed an 18-play, 75-yard TD drive to reduce the deficit to five points.

Veteran backup Chad Henne was called in for Kansas City and promptly followed up a pair of promising passes with an end-zone interception, giving the ball back to Mayfield in the fourth quarter.

However, an epic back-and-forth saw the Browns forced to punt with under four minutes remaining, and Henne came up with two huge plays inside the two-minute warning as head coach Andy Reid gambled on a pass from fourth and inches to clinch victory and a Championship Game against the Buffalo Bills with a vital first down.

Patrick Mahomes was ruled out of the rest of the Kansas City Chiefs' clash against the Cleveland Browns following a concussion evaluation.

Mahomes was evaluated for a concussion before being officially ruled out.

He completed 21 of 30 passes for 255 yards and a touchdown.

The Browns reduced the Chiefs' lead to 22-17 early in the fourth quarter.

The Wild Card Round was, well, wild.

The Buffalo Bills and Cleveland Browns ended long postseason droughts, while the Los Angeles Rams and Baltimore Ravens impressed as they produced upset results on the road.

Meanwhile, Tom Brady made sure the Tampa Bay Buccaneers progressed, securing a showdown with Drew Brees and the New Orleans Saints that will be an all-NFC South battle between starting quarterbacks with a combined age is 85.

As for the Kansas City Chiefs, the reigning Super Bowl champions - along with NFC top seeds the Green Bay Packers - prepare to return to action after a well-earned bye week.

A four-game schedule has all the potential for another bumper weekend of NFL action, with fans watching on to found out who will be the final four left standing in the playoffs.

Los Angeles Rams at Green Bay Packers - Saturday, 4.35pm (all times Eastern)

- The Rams are the only current NFC team with an all-time winning record against the Packers (46-45-2), but they have lost five of the previous six and 11 of the past 15 meetings. Green Bay, meanwhile, earned the No.1 seed in the conference for just the third time in their history.

- Aaron Rodgers posted the second-highest passer rating in NFL history this season (121.5), trailing only his own 122.5 in 2011, when he was voted the league's MVP. Rodgers had six games with four or more touchdown passes and zero interceptions, tying the most in a season all-time (Peyton Manning in 2013). In Rodgers' playoff career, the Packers are 8-1 when he does not throw an interception - but 2-7 when he does.

Baltimore Ravens at Buffalo Bills - Saturday, 8.15pm

- Baltimore (191.9) and Tennessee (168.1) finished first and second in the NFL in rushing yards per game in the regular season, but the Ravens out-rushed the Titans 236-51 last week to progress. Lamar Jackson ran for 136 of them, the third most ever by a quarterback in a playoff game.

- Josh Allen completed 26 of 35 passes in the Wild Card win over the Indianapolis Colts (74.0 per cent), the highest completion percentage by a Bills starting QB in a playoff game. Allen also became the fifth player in NFL history with a passing TD, a rushing TD and a receiving TD in the playoffs, joining Freeman McNeil, Kordell Stewart, Julian Edelman and Nick Foles.

Cleveland Browns at Kansas City Chiefs - Sunday, 3.05pm

- This is the first postseason game between the teams. The Chiefs have won the past three meetings, most recently on November 4, 2018 (37-21). In fact, Cleveland have not beaten Kansas City since December 2012, while they have triumphed at Arrowhead only once in the past 32 seasons (December 2009).

- Against the Steelers, Baker Mayfield became the seventh player in league history to throw at least three TD passes without an interception in his postseason debut. Only one other player has done this in the previous 15 years (Alex Smith in 2011). He goes up against Patrick Mahomes, who has accounted for 16 total touchdowns – 13 TD passes and three rushing scores – in five postseason outings.

Tampa Bay Buccaneers at New Orleans Saints - Sunday, 6.40pm

- This will be the 59th all-time meeting of these franchises, albeit the first in the postseason. The Saints have won five straight in the rivalry, outscoring the Bucs by a combined 165-81 during that streak.

- Brady's two touchdown passes against the Washington Football Team moved his career postseason total to 75, while the victory was his 31st in 42 career playoff starts. In the entire NFL, only five teams have as many as 31 postseason wins in their history. Brady (341) and Saints QB Brees (303) rank first and third respectively in career starts among quarterbacks, regular season and playoffs combined.

LeBron James and Patrick Mahomes were among the stars to wax lyrical over DeVonta Smith, who said Alabama "finished writing our story" in the College Football Playoff National Championship.

Heisman trophy winner Smith was in sensational form at Hard Rock Stadium in top-ranked Alabama's (13-0) 52-24 rout of Ohio State (7-1) on Monday.

The exciting wide receiver, who is NFL bound for the 2021 season, had 12 catches for 215 yards and three touchdowns, all in the first half as Alabama claimed a 35-17 lead at the interval.

The 22-year-old recorded 200-plus receiving yards and three or more touchdown catches for the third time this season, tying Davante Adams (2013) for the most such games by any FBS player in the last 25 seasons, according to Stats Perform.

Smith also broke the South Eastern Conference's single-season receiving yards record as he was named Offensive Most Valuable Player.

What was most impressive is the fact Smith missed the majority of the second half with a right hand injury, though he said after the game "I'll be alright" when asked about the issue.

Speaking about the achievement, in quotes reported by ESPN, Smith said: "It came down to the young guys just putting in the work, every day, every week, knowing if somebody went down, they were going to have to come in and do something big. 

"I believed in them from the jump. That's what we do, that is why you come to Bama.

"Just with COVID and everything going on it made things tough, made us more together as a team, be there for each other. This team is like no other.

"It's been an unbelievable [season]. We just finished writing our story, that was the whole thing of us coming back, just finishing the story that we wanted to write and we did that."

Social media was abuzz watching Smith's performance, with Los Angeles Lakers superstar James hailing the youngster on Twitter.

"DeVonte Smith is one of the best pure receivers I've ever watched! Like a mix between Reggie Wayne and Marvin Harrison. Man he's good!" James wrote.

Mahomes, who led the Kansas City Chiefs to Super Bowl glory last season, merely posted: "Lol they just need to put like everybody on him".

After seeing his record tied, Adams joked: "From now on if u misspell my name make sure it’s Devonta cuz he that boy."

J.J. Watt added: "DeVonta is going crazyyyyyy!!!!!!!"

The win saw head coach Nick Saban win a seventh college title, surpassing Paul Bryant for the most national championships, with six of those titles coming during his 14 seasons at the helm of Alabama.
