Michigan quarterback Jack Tuttle announced Monday that he is medically retiring from football.
Tuttle, a seventh-year senior, played in two games for the Wolverines this season, with one start.
During the offseason, Tuttle underwent surgery to repair the ulnar collateral ligament in his throwing arm. Tuttle said the arm "didn't fully recover" and that he continued to have "ongoing issues" with it.
Tuttle also said he recently suffered the fifth concussion of his career. He said that "brought forth the painful truth: that I need to start prioritizing my health."
Tuttle began his career at Utah, then transferred to Indiana, where he backed up Michael Penix Jr.
