Jimmah injured

On second down in ND's previous series, Jimmah faced a heavy rush, appeared to "turtle" (crouch down and tuck) and was down after the play. On replay, it looked like he turned his ankle which caused him to crouch instead of trying to evade the rush. He was taken off, Dave Chryst (sp?) threw a screen pass and the offense punted. ND also just got back to back 15-yard penalties on defense. I have been amazed at his ability to stay in the game after the poundings he's taken the past two years, but he is still being looked at for this one. Topic: can an emu turtle? Talk amongst yourselves.
