Wisconsin quarterback Danny O'Brien has left the program after one season with the Badgers, according to multiple media reports.
O'Brien's high school coach, Todd Willert, told both Fox Sports Wisconsin and the Wisconsin State Journal site that O'Brien informed him he won't return to Wisconsin for the 2013 season. The Milwaukee Journal Sentinel also reported the news, citing a team source.
The quarterback started the 2012 opener for the Badgers after transferring to the school from Maryland, where he started in 2010 and 2011. O'Brien graduated from Maryland in three years and transferred to Wisconsin without having to sit out a season, retaining two years of eligibility. He now has one year left.
O'Brien struggled for Wisconsin in 2012, completing 52 of 86 passes for 523 yards with three touchdowns and an interception. He also fumbled five times, losing three of them. He lost his starting job to Joel Stave in Week 4, and the team turned to Curt Phillips rather than O'Brien after Stave suffered an injury in a Week 9 loss to Michigan State.
O'Brien competed for the starting job this spring under new head coach Gary Andersen, but Stave and Phillips emerged from the session as the frontrunners for the job. Willert told Fox Sports Wisconsin that he wasn't sure if O'Brien would continue to pursue football.
