Oklahoma City police said Derek Loccident was trying to crawl under a stopped train when the train started moving. Police said the train severed Loccident's foot, but he was able to flag down a nearby person who took him to a hospital.
Police say he is expected to survive.
Loccident is a defensive back for the Division II school, which competes in the Mid-America Intercollegiate Athletics Association. He recorded 15 tackles in the team's first two games this season.
UCO's athletic department said in a statement that Loccident and his family have the school's full support. What a freak accident.
