Duncan police say Junior Harris was south bound on Highway 81 near the intersection with Osage Road when his vehicle left the road, hit a ditch and rolled over.
Police do not believe he was wearing a seat belt and he was ejected and died at the scene from head trauma.
Officers say Harris was returning to Duncan from Lawton where he had been playing golf. Police say they found nothing to indicate alcohol or drugs were involved.
