The Chiefs and the Steelers got the penultimate week of the 2024 NFL season going with a mouthwatering game at lunchtime on Christmas Day. Both teams had already made it to the playoff, but that didn't mean that nothing was riding on the game.Kansas City had a 14-1 record coming into Week 16 and knew another win would guarantee them the top seed in the AFC and the Wild Card Bye. With the Buffalo Bills having a 12-3 record, a win would put the Chiefs out of their reach.For Pittsburgh, the 34-17 loss to Baltimore last week means that they are tied with the Ravens atop the AFC North with a 10-5 record. A victory here would give them a lead and put pressure on Lamar Jackson and company to get a result against the Texans later today.With so much riding on this game between two high-quality teams, this is how the action went down.Chiefs vs. Steelers box scoresQuarter1234TotalChiefs13031329Steelers073010Chiefs Box ScorePassingPlayerC/ATTYDSAVGTDINTSACKSRTGPatrick Mahomes29/383208.4300-0127.1Team29/383208.4300-0127.1RushingPlayerCARYDSAVGTDLONGKareem Hunt9202.216Isiah Pacheco618308Patrick Mahomes11212012Xavier Worthy210506Samaje Perine294.509Team20693.5112ReceivingPlayerRECYDSAVGTDLONGTGTSTravis Kelce88410.512011Xavier Worthy8799.91219Justin Watson260301492Hollywood Brown44611.50177Samaje Perine220100142JuJu Smith-Schuster21890132DeAndre Hopkins273.5044Noah Gray166061Team293201134938DefensePlayerTOTSOLOSACKSTFLPDQB HTSTDINTINT YDSChristian Roland-Wallace1060000000Drue Tranquill960000000Nick Bolton830020000Justin Reid550010010Mike Danna532302000Trent McDuffie440010000Jaden Hicks420010000Felix Anudike-Uzomah331101000Deon Bush320000000Nazeeh Johnson320000000Swayze Bozeman320000000Tershawn Wharton311102000Bryan Cook310000000George Karlaftis221112000Cam Jones220001000James Winchester200000000Joshua Williams200020000Charles Omenihu110001000Keith Taylor Jr.110000000Derrick Nnadi100000000Noah Gray100000000Leo Chenal100000000Team76465689010FumblePlayerFUMLOSTRECNikko Remigio100Deon Bush001Nick Bolton001Team102KickingPlayerFGPCTLONGXPPTSHarrison Butker1/1100322/35Team1/1100322/35Steelers Box ScorePassingPlayerC/ATTYDSAVGTDINTSACKSRTGRussell Wilson23/372055.5015-4365.7Team23/371625.5015-4365.7RushingPlayerCARYDSAVGTDLONGNajee Harris13745.7020Jaylen Warren11716.5022Russell Wilson6559.2115Cordarrelle Patterson12202Team312026.5122ReceivingPlayerRECYDSAVGTDLONGTGTSPat Freiermuth7608.60158George Pickens35016.70417Jaylen Warren5418.20216Calvin Austin III4317.80145Connor Heyward188081Darnell Washington188081Najee Harris273.5054Mike Williams000002Van Jefferson000001Team232058.904135DefensePlayerTOTSOLOSACKSTFLPDQB HTSTDMinkah Fitzpatrick7600000Patrick Queen7500000Donte Jackson4400000Alex Highsmith4300100Payton Wilson4300000Cameron Heyward4201010DeShon Elliott4200000Cameron Sutton3300100Cory Trice Jr.3300100Elandon Roberts3200000Larry Ogunjobi3200000T.J.

The Kansas City defense set the tone with a three-and-out and Patrick Mahomes responded with a touchdown drive. A pass to Xavier Worthy made the score 6-0, but an unsportsmanlike conduct on the wide receiver pushed the one-point conversion back, which Harrison Butker missed.After the Steelers punted again, the Chiefs made them pay once more. Another possession ended with Patrick Mahomes' 244th career touchdown pass. That equals Peyton Manning as the most in a player's first eight years in the league, which is even more impressive since the Kansas City star was a backup in his first year. That made the score 13-0.The Steelers thought they had a response but an offensive holding penalty ruled out a rushing touchdown. Russell Wilson threw a pick on the next snap and that fizzled out. Thankfully for the home fans, the Pittsburgh defense forced a punt from the visiting team on the next possession. That allowed the hosts to mount a mini-comeback with the Steelers quarterback rolling back the years to scramble into the endzone to make it 13-7.Three punts by either team followed as defenses made their presence felt and that is how it finished at the break. Kansas City and Pittsburgh came back after halftime and exchanged a couple of field goals to make it 16-10. However, it was after that the visitors showed their championship caliber and pulled ahead.First, the Chiefs marched down 77 yards, and Kareem Hunt ran into the endzone to make it 22-10 to begin the fourth quarter. The two-point conversion failed but it did not matter as Pat Freiermuth fumbled the ball on the next drive to allow Kansas City to score again. Patrick Mahomes threw to Travis Kelce as the two Chiefs' stars connected to make it 29-10.With that score, the quarterback cemented himself as the most productive touchdown thrower in the first eight years of their career. The tight end made franchise history by passing the legendary Tony Gonzalez for the most touchdown catches.The Steelers tried to come back gamely but turned it on downs in the next drive. That pretty much ended any fight they had in them because when they got the ball back next after a Chiefs' punt, they decided to kick the ball away on a 4th-and-2. It was an indication that they had downed their tools. Kansas City, meanwhile, are the top seed in the AFC yet again.
