Nose tackle Brandon Williams has been one of the Ravens' most consistent performers but he was temporarily forced out of today's game against the Miami Dolphins after the first defensive possession.
He missed one full series before jogging out of the locker room and returning to the game.
It isn't clear what was wrong with Williams, who has been the anchor of the Ravens run defense. Williams has started all 12 games for the Ravens and he entered the game with 40 tackles and two sacks.
Through three possessions, the Dolphins have 10 rushing attempts for 58 yards.
