Wegher transferred to OU this semester after sitting out last season at Iowa.
Wegher rushed for 641 yards his freshman year at Iowa but last summer left the team two days into fall camp for personal reasons. He didn't play a down last season. Iowa granted a release from his scholarship before Christmas.
He informed coach Bob Stoops of his plans to transfer earlier this month after laying the ground work with running backs coach Cale Gundy.
Wegher said he grew up an OU fan after visiting his aunt, who owned a barber shop on campus in Norman before she moved back to the South Dakota/Iowa area five years ago.
