Richard Sherman hurt his arm in the fourth quarter of the NFC Championship game.
Sherman got his left arm tangled up when tackling James Starks on the sideline. He was slow to get up and was shaking his arm in pain as he ran back onto the field, but did stay in to finish the series. Trainers checked out his wrist, forearm and bicep on the sideline, the vine of which can be seen above.
Sherman hyperextended his elbow, but an x-ray came back negative. An MRI showed that his elbow is sprained, but he should be able to play in the Super Bowl.
