Michigan has lost another player to an ACL injury.

The football program announced Thursday morning that rising sophomore tight end Jake Butt is out indefinitely after suffering a torn anterior cruciate ligament during winter conditioning drills.

Butt is the sixth Wolverine to go down with this injury in the past year.

"Jake's done a tremendous job since he's been here," Michigan coach Brady Hoke said in a statement. "He's worked extremely hard and gained a lot of weight to become the complete tight end he wants to be. I think he showed flashes of that towards the end of last season.

"This is a tough break, but because of his work ethic and attitude, the kind of young man he is, we know he will be back as soon as he can and as strong as ever."

Quarterback Russell Bellomy, linebacker Jake Ryan, defensive tackle Ondre Pipkins, offensive lineman Joey Burzynski and running back Drake Johnson have all suffered the same injury over the past year.

Blake Countess, Chris Wormley (ACLs) and former linebacker Kaleb Ringer (knee) have also suffered knee injuries since Hoke took over as the program's head coach in 2011.

Butt had a terrific freshman campaign at tight end, saving his best football for later in the year. He finished with 20 catches for 235 yards and five touchdowns. His best game came against Ohio State, a 5-catch, 85-yard, touchdown performance.

The 6-foot-6, 237-pounder would have likely been Michigan's starting tight end in 2014 if the Wolverines chose to push Devin Funchess out to a full-time wide receiver role.
