First, during the game they said it was an injury during the ND game. At half-time Bob Joyce on WTIC said he rode on the plane and didn't even realize she wasn't on it, so that's no help. Then I saw a post somewhere that said it was from an injury in practice. And in the After-game wrap-up they said it was from the elbow to the face in the ND game..
That elbow looked awful - could have been to the nose. But that doesn't seem to me to be likely concussion territory. And it seems strange that it was kept so quiet or at least down-played before the game.
