Craft, Brehaut throwing around, Prince not spotted

I'm combing the sidelines and field before the start of the second half, and I don't see Kevin Prince anywhere. That is a really bad sign for UCLA, with all indications pointing toward a serious injury.
Kevin Craft is starting the half at quarterback for UCLA.
The announcer in the press box said Prince is being evaluated for concussion-like symptoms and his return is questionable.
Prince was knocked out with 5:07 in the second quarter after completing 13-of-17 passes for 212 yards and a touchdown and an interception.
Stay tuned.
