INDIANAPOLIS -- Indiana quarterback Tre Roberson could return to campus as early as Wednesday following surgery on his broken lower left leg.

Coach Kevin Wilson doesn't expect Roberson to be back on a football field any time soon.

Wilson told radio listeners Monday that the sophomore had a ''clean'' break in his lower leg. On Sunday, doctors inserted a titanium rod and that it will likely take Roberson five to six months to make a full recovery.

''He has high goals, high standards and he's a special kid, and we will have him for three more years,'' Wilson said on his weekly radio show, explaining the Hoosiers would redshirt Roberson.

Roberson, Indiana's 2010 Mr. Football, was hurt during the first half of Saturday's 45-6 victory against Massachusetts.

As he ran toward the end zone, Roberson stretched for the goal line and several players came down on his left side, pinning his leg underneath him. Trainers immobilized the leg on the field, then lifted him onto a stretcher and he was driven off of the field in an ambulance.

Junior college transfer Cameron Coffman replaced Roberson in the game and is expected to start this weekend when Indiana (2-0) hosts Ball State (1-1). Indiana has only one other quarterback on its roster, freshman Nate Sudfeld.

Wilson said Roberson's mother has been with her son, and that Roberson is already thinking about his future with the team.

''He's talking about [Robert Griffin III] and how he had a broken ankle his sophomore [season] and how he went on to have a pretty good career,'' Wilson said, referring to last year's Heisman Trophy winner.

Roberson has been Indiana's starting quarterback since the last five games in 2011. He was the first freshman quarterback to ever start in the position for the Hoosiers. He finished the season going 81 of 142 for 937 yards with three TDs and six interceptions. Roberson also ran for 426 yards, but was 0-5 as a starter.

Coaches spent much of the offseason working with Roberson on throwing, trying to help him become a more accurate passer.

Roberson was 33 of 50 for 368 yards with two TDs and one interception. His passing efficiency was 137.02 before the injury. He also had 12 carries for 133 yards and three touchdowns, with runs of 50 and 39 yards against UMass.
