You have to be careful when approaching a "tweener" on the baseball field. If you aren't, this can happen. Damon and Damian Jackson both hustled after this pop-up in the 2003 ALDS, but unfortunately each failed to take notice of the other one. The subsequent collision knocked Damon unconscious and cut up Jackson's face. Damon, never a rocket scientist to begin with, ended up being fine and returned for Game 3 of the ALCS. Jackson continued his journey as a MLB utility man until 2007, when nobody really wanted him anymore and he was forced to resort to the Atlantic League.
