Great news that he didn't have any serious injury, although it is a bit hard to believe. I was almost sure as the day went on that they'd announce that he had a serious concussion, but that's not the case.
Also, this incident is part of the reason I haven't been as upset when he's run 18-20+ times in a game. Against Purdue he didn't have many designed rushes, but still got hit a lot and was knocked out of the game on one of the times he kept a read play. Overall in 2.5ish (can't remember exactly when he went out) quarters of play, he still had 12 carries and honestly, if he's going to get those carries getting hit in the backfield or scrambling for 2 yards with guys gang tackling him, I'd rather just have designed rushes and have the coaches get in his ear about getting OOB after he's picked up a first down. Now he still did have a decent amount of option plays in which he could try to keep the ball, and teams are going to key on him more, but if there is a way to sneak in a few lead plays that they ran against MSU and NEB, I think it would help more.
Now that he's been hurt though, I'm not sure how they'll handle the offense. He has no lasting injuries, but I think it's going to be in the coaches minds even more to try and limit his carries. Might even sit him against PSU. I'm interested to hear what Urban says during the week.
