KANSAS CITY, Mo. — Late in the third quarter, Kansas City Chiefs safety Tyrann Mathieu appeared to get his legs tangled up with Pittsburgh Steelers wide receiver Chase Claypool.
Mathieu could be seen favoring his left knee briefly and left the field for the next play.
But he quickly returned and finished the drive before Mathieu was ruled out for the remainder of the game.
With the Chiefs in control, up 33-3 early in the fourth quarter as the defense returned to the field, the team announced that Mathieu was out with a quad injury.

He is the second starter to leave the game with an injury, joining running back Clyde Edwards-Helaire, who left with a collarbone injury.
