On the first day of drills last week, Bush saw action at both running back and safety before breaking his right foot after making a routine cut during drills.
Bush, who had successful surgery last week to repair the break, will miss the remainder of spring drills, including the annual Red/White game.

"He's doing good," Petrino said of Bush. "It's probably harder now than it was when it happened because he's sitting around not doing alot. And that's hard on Michael because he's never done that."
"His spirits are real good," Petrino continued. "I stopped by when he was in the hospital and he was doing good. He's going to every class and his grades have been very good. It's a tough break but the best thing is that he's got alot of time to get back before that opener. It could have happened in September, so we're actually lucky it happened now."
Bush is expected to make a full and complete recovery and will wear a cast for the next 4-6 weeks.
