Notre Dame safety Chris Badger will transfer to BYU, his father, Rod, told The Salt Lake Tribune.
Badger will file an appeal for a waiver to play immediately with the Cougars because of a personal hardship.
The Provo, Utah native signed with the Irish in 2010 and enrolled in January, but he left school for more than two years to participate in a mission in Ecuador for the LDS Church.
Badger would have been a sophomore at Notre Dame this season, though he was buried on the depth chart and did not figure to see significant action.
Elsewhere, Irish coach Brian Kelly told the Chicago Tribune that freshman quarterback Malik Zaire has mononucleosis, though he may be in the recovery stages.
