KANSAS CITY (KSNT) – After a slow start, the Chiefs and Patrick Mahomes turned things on in the second quarter and dominated the Pittsburgh Steelers 42-21.

Mahomes put on a show at Arrowhead Stadium in the win. He threw for 404 yards for five touchdowns. But he wasn’t the only Chief to throw for a touchdown Sunday night.

Tight end Travis Kelce found the end zone twice, once as a receiver and once as a quarterback. Kelce connected with Kansas State’s Byron Pringle to put Kansas City up 28 points to start the fourth quarter. It was a full team effort on display as five players recorded at least one touchdown.

The game started slow with punts on the first five drives. Then Mahomes threw an interception on the next Chiefs drive. The Steelers got on the board first on a scoop and score touchdown from TJ Watt to put Pittsburgh up 7-0.

The Chiefs answered and got on the board themselves with 5:45 to play in the second quarter on a four yard touchdown pitch from Patrick Mahomes to Jerick McKinnon to tie the game. This opened the flood gates for the Chiefs scoring.

Kansas City scored two more touchdowns before the end of the half. First, Mahomes connected with Pringle for a 12-yard touchdown pass with 1:55 left to give the Chiefs the 14-7 lead. Then Mahomes went to Travis Kelce for a 48-yard touchdown that made it a two possession game.

The Chiefs continued to pour it on in the third quarter. Mahomes threw a one-yard pass to offensive lineman Nick Allegretti. The touchdown from the 315 pound guard gave put the Chiefs on top 28-7. Tyreek Hill got in on the fun when he caught a 31-yard touchdown pass with 9:14 to play in the third to make it 35-7.

The Chiefs scored one final touchdown in the fourth quarter when Reid gave Travis Kelce a chance to throw it. The Steelers scored two touchdowns in the second half to keep the game within three scores but never threatened to take the lead after they lost it in the second quarter.

Mahomes threw for 404 yards and five touchdowns in the win. He’s one of only two quarterbacks in NFL history with 400+ passing yards and 5+ passing touchdowns in a single playoff game.

Travis Kelce’s 108 receiving yards put him over 1,000 career postseason receiving yards. Kelce joins Buccaneers tight end Rob Gronkowski as the only two tight end’s in NFL history to reach that mark.

Jerick McKinnon led the team in rushing with 61 yards on 12 carries. McKinnon also racked up 81 receiving yards. K-State’s own Byron Pringle tallied 37 rushing yards to go with his two touchdowns.
