Boston Celtics center Ryan Hollins thought that he had it made when he went up for an alley-oop during game 1 of the Eastern Conference semifinals against the Philadelphia 76ers. Unfortunately for Ryan, and his back, everything went wrong. Hollins went up and fumbled the pass to dunk transition and landed VERY HARD on his back. We repeat, VERY HARD on his back.
