The Division II school announced Tuesday that Hill is joining the program and will be in uniform for Saturday's opener against Stillman College.
Hill was dismissed from Oklahoma State's football and track teams in December 2014 following his arrest on domestic violence charges. An All-Big 12 Conference all-purpose player, he was accused of punching and choking his pregnant girlfriend. He pleaded not guilty in January.
The arrest came less than a week after Hill's 92-yard punt return in a comeback victory over Oklahoma.
Hill was arrested on a charge of domestic abuse by strangulation.
He had ranked second nationally in total kick return yards.
