Bengals center Kyle Cook could be lost for the season because of a foot and ankle injury, the second significant setback to Cincinnati's offensive line during the preseason. Cook hurt his right foot and ankle when a defender fell on it during a preseason game on Thursday night. He didn't think it was a severe injury at first and stayed in the game. He showed up at Paul Brown Stadium on Monday expecting to practice. Doctors sent him for precautionary X-rays and an MRI that found a more significant problem. He had a protective boot on his right foot on Tuesday in the locker room.
