The Pittsburgh Steelers have lost one of their starting offensive lineman to an injury in the first half of their Sunday night game against the Kansas City Chiefs.
Tackle Marcus Gilbert had to leave the game in the second quarter with a left ankle injury. He was replaced in the game at right tackle by Ryan Harris.
Gilbert got his left ankle trapped under a pile of players. He is questionable to return to the game.
The Steelers now lead the Chiefs 29-0 late in the first half.
UPDATE: Gilbert has now been ruled out for the rest of the game.
