(NBC Washington) Bowie State University fired a former NFL player from his volunteer football coach position after TMZ Sports posted video of him body-slamming a student.

University police is investigating Charles Grant. He can be heard shouting and cursing at the student before throwing him to the ground then into the bleachers as people are heard laughing in the background.

Grant is a former defensive lineman for the New Orleans Saints. He was on the team the season it won Super Bowl XLIV.

Grant previously was brought up on an involuntary manslaughter charge after a deadly shooting outside at a bar in Georgia. The charge was later dropped, and he pleaded no contest to public fighting.

In a statement, Bowie State said in part, “The Department of Athletics has zero tolerance of behavior that violates the University’s core values and jeopardizes the welfare of student-athletes.”
