Michigan sophomore tight end Jake Butt underwent successful surgery to repair a torn anterior cruciate ligament roughly two weeks ago.

And while his rehabilitation process is currently in its infancy, Michigan coach Brady Hoke says things are going well. Asked when, exactly, the team hopes Butt might be able to return to the field -- Hoke says nothing is set in stone at this point, but there is a rough target.

"I haven't really sat down and talked with the doctors because he just had it done and all that, but he'll work hard," Hoke said. "I would think, though, to really have him back where you want him, it (probably wouldn't be at least) until game three or game four.

"But we'll have to see, everybody heals differently."

Hoke says, at the moment, Michigan is looking at a similar timeline for Butt's rehab as it did a year ago with now senior linebacker Jake Ryan.

Ryan tore his ACL in mid March, and eventually made his on-field return at Penn State on Oct. 12 -- roughly seven months after the injury itself.

Butt, meanwhile, tore his ACL on Feb. 13 -- an entire month before Ryan tore his last spring. If Hoke's rough projection is correct, and Butt's rehab goes without any problems, there could be the potential for a return by mid to late September.

Michigan hosts Miami (Ohio) in week three (Sept. 13) and hosts Utah in week four (Sept. 20).

The Wolverines begin Big Ten play the following week at home against Minnesota.

"It just depends on what he does for it," Ryan said earlier this spring when asked about Butt's rehab. "I worked as hard as I could (to get back), and Jake can do the same.

"It just depends on how his body reacts to it."

With Butt currently on the sidelines, Michigan's tight end battle currently features converted defensive lineman Keith Heitzman, junior A.J. Williams and redshirt freshman Khalid Hill. Hoke also mentioned walk-on sophomore Michael Jocz as a player who could fight for time early.
