Lamar Jackson suffered an ankle injury and is questionable to return to Sunday's game against the Tennessee Titans.
Jackson is still on the Ravens sideline in uniform with his helmet off.
Jackson suffered the injury as he tried to scramble away from Titans defensive end Jermaine Johnson on the Ravens' final offensive play of the first half.
Johnson landed on the back of his leg for a sack. Jackson hopped to his feet but met with the team's medical staff on the bench before going to the locker room early.
