According to the AP, OSU’s top receiver (Ted Ginn Jr) was injured while celebrating his opening kick-off return for a touchdown (aided by a holding non-call though it may have been).
Kidding aside, I think I feel worse for Ginn than I do for Troy Smith. You look forward to this game for almost two months, and you get injured after less than thirty seconds (game time). Then, you have to watch helplessly from the sidelines as your team implodes.
