CLARKSVILLE, Tenn. (AP) Concussion-related issues have caused Austin Peay running back Otis Gerron to end his college career.

Gerron had rushed for a team-high 596 yards last season despite missing most of two games because of a concussion. He left Austin Peay's 52-6 loss to Southern Mississippi last week because of concussion-like symptoms.

The school issued a release Friday saying that ''after consulting with medical personnel this week, it was decided it was in Gerron's best long-term interests to conclude his playing career.'' Austin Peay coach Kirby Cannon said in a statement that, ''it was mutually decided that enough was enough.''

Cannon says Gerron has the option of remaining involved with the team in another capacity.

Austin Peay (0-2), a Football Championship Subdivision program, plays Saturday at Vanderbilt (0-2).
