Chiefs QB Patrick Mahomes diagnosed with high ankle sprain, but expected to play AFC title game

Kansas City Chiefs quarterback Patrick Mahomes was diagnosed with a right high ankle sprain during Saturday's win against the Jacksonville Jaguars.

Mahomes is expected to play in the AFC championship game, but he probably won't be playing at 100%.

Mahomes suffered the injury during the second quarter, but returned to start the second half. During one of his first plays back, Mahomes ran for a first down. The Chiefs said the QB was questionable to return when he left the game midway through the second quarter.

Mahomes suffered the injury when he was taken down by Jaguars linebacker Arden Key and defensive lineman Corey Peters after a passing play with less than two minutes remaining in the first quarter. Mahomes' leg went sideways during the takedown.

Mahomes briefly limped toward the Chiefs sideline, and returned to the field to finish the first quarter. As the first quarter ended, Mahomes limped to the sidelines to be evaluated on the bench. He got his ankle taped and returned to the game as the second quarter began to finish a field-goal drive.

NBC reported early in the second quarter that Mahomes appeared adamant during a conversation with Chiefs coach Andy Reid and a trainer. But Mahomes left for the locker room several minutes later and was shown back on the sidelines later in the quarter. He finished the 27-20 win with two touchdown passes on 22 of 30 passing and 195 yards.

Chad Henne, the Chiefs’ 37-year-old backup, entered the game midway through the second quarter in place of Mahomes.

Mahomes was 12 of 15 passing for 84 yards before leaving, throwing an 8-yard touchdown to tight end Travis Kelce on Kansas City’s first drive. The Jaguars responded with a 10-yard touchdown pass from quarterback Trevor Lawrence to receiver Christian Kirk in the first quarter.

Henne threw his first career playoff touchdown on his first drive, connecting on a 1-yard score to tight end Travis Kelce to increase Kansas City's lead to 17-7 with 3:54 left until halftime. The drive was aided by a 39-yard run by running back Isiah Pacheco. Henne went 5 of 7 for 23 yards.
