The Bengals initially said Uzomah was doubtful to return before ruling him out after halftime of their eventual 27-24 overtime win. He returned to the sideline, using crutches, in the second half.
There was no update on his injury postgame.
Uzomah went down after he tried to leap to make a catch in the first quarter of the game at Arrowhead Stadium. He stayed down briefly before he hobbled off the field, unable to put any weight on his left leg.
After a brief evaluation on the team's bench and then inside the injury tent, Uzomah was taken via cart to the locker room. On the way, a visibly distraught Uzomah repeatedly buried his face in a white towel.
The former Auburn standout has been a key player in Cincinnati's best playoff run in 33 years, which now sees the Bengals headed to the Super Bowl. Coming into Sunday's game, he had 13 catches for 135 yards and one touchdown.
He had zero catches on two targets when he left the game.
