It might be nothing more than some local irritation from the swelling, but the laceration required stitches, and it’s on the middle finger of the hand, pretty important for spinning the ball and throwing it.
He tried to throw in pregame at the last game and just couldn’t get the ball down the field. The laceration has healed, so the only real explanation for that is a little bit of nerve damage. Will it persist? I don’t know. But he is still struggling with it.
