Just saw this on twitter from Jeff Goodman @goodmanESPN Michigan's Spike Albrecht told ESPN he was granted his release today and plans to play elsewhere as a grad transfer
Can't find any other link as of now (12:35am)
Thought he was retiring because of his hip problems and having 2 hip surgeries.
Best of luck to the kid, hope he does well (unless he ends up at another B1G school, haha!)
