Chiefs center Mitch Morse was injured in the fourth quarter. It appeared he was holding his left foot as he sat on the ground with 6:51 left in the game.
Zach Fulton replaced Morse, and the Chiefs scored on a 15-yard touchdown catch by Travis Kelce on the next play to take a 20-13 lead.
Morse has started all but one game in his three-year career after the Chiefs made him a second-round pick in 2015.
UPDATE 3:53 P.M. ET: The Chiefs announced Morse is doubtful to return with a foot injury.
