He then had sports hernia surgery during the summer, and was forced to miss most of fall camp. He was dressed for the season opener against FAU but never entered into the game.
Now, the coaches are hoping he'll be ready to go for Saturday's showdown against Florida.
"He looked better today," Al Golden said. "He was moving around. It'll come down to the wire but he's looking a lot better."
If Bush is unable to go, Kacy Rodgers will likely get the start in his place.
"Kacy did a good job of running the show, getting people lined up, and he tackled well," Golden said of the senior's performance last Friday night.
While the Hurricanes went into the FAU game relatively healthy, they lost a key player in the wide receiver rotation when junior Rashawn Scott went down with a shoulder injury in the 4th quarter.
"It'll be about a month probably," Golden said when asked how long Scott will be out. "Without giving a diagnosis, it sounds like a month. It won't require surgery so we have to stay positive, and he'll be ready when the time comes. We have a bye week early this year so that will benefit him."
Redshirt freshman D'Mauri Jones will take Scott's spot in the rotation. Phillip Dorsett, Allen Hurns, and Herb Waters remain the starters. Stacy Coley and Malcolm Lewis will be the first two guys off the bench, followed by Jones and possibly walkon Garrett Kidd.
