CHATTANOOGA, Tenn. (AP) -- University of Tennessee at Chattanooga linebacker Bo Dyer is out indefinitely with a blood clot, although Mocs coach Russ Huesman says his status for the season remains unknown.

The Chattanooga Times Free Press reports that Dyer, a redshirt sophomore from Gatlinburg who played running back last season, has a blood clot in a lung and is taking blood thinners.

UTC head athletic trainer Todd Bullard said anyone taking blood thinners is unable to play because the body can't "take any type of trauma."

The Mocs begin preseason practice on Aug. 4 and open their season at home against Appalachian State on Sept. 4.
