University of Louisville football coach Bobby Petrino delivered some bad news to start the ACC Media Day on Friday, announcing that senior defensive end Trevon Young will redshirt this season.

Young was injured in the first quarter of the Music City Bowl last season and was trying to make it back by the start of the season. But Petrino said that's now not the case. He will redshirt and play the 2017 season.

"It was a bad injury but he was doing really well and was ahead of the recovery," Petrino said. "He gave us some life to think that he might play this fall and then all of a sudden he hit a point to where he wasn't getting any better.

"There was some clicking going on in his hip and some pain."

Young went back to Nashville to see the surgeon recently and they did a second surgery to repair the labrum in his hip. Petrino said it was then he decided sitting out this season would be the best option.

"I talked to his mom the other day and she said he's doing really well with it," Petrino said. "Now that he knows he has a year to get ready he's doing great and it takes some pressure off him."

Young was second on the team and seventh in the ACC last season with 8.5 sacks.

Petrino said he expects James Hearns and Jonathan Greenard to step into the role where Young would have been playing.
