Illinois starting quarterback Wes Lunt will miss four-to-six weeks after suffering a broken leg in Saturday's home 38-27 loss to Purdue, the team announced on Sunday.

Lunt, who leads the Big Ten with 313.8 passing yards per game, was noticeably limping before being removed late in the game. Senior Reilly O'Toole will likely start this week's game against Wisconsin, and the team could cancel its plans to redshirt backup Aaron Bailey. The Illini (3-3) have two bye weeks in the next month, so Lunt may only miss two or three games.

"I'm very disappointed for Wes, his family and the Fighting Illini family, but I know we all will respond to this situation in a positive way," head coach Tim Beckman said in a statement released by the school. "He's having an outstanding season and we're very hopeful to have him back on the field for the final three games. "

Lunt is in his first year of starting for Illinois after transferring from Oklahoma State following the 2012 season. He has completed 66.5 percent of his passes for 13 touchdowns and three interceptions, ranking fourth in the FBS with 14 completions longer than 30 yards.
