USF DT Cory Grissom breaks ankle

USF starting defensive tackle Cory Grissom broke his right ankle during practice Monday and is out for the rest of spring, the school announced.

Grissom will undergo surgery Thursday, and there is no timetable for his return. USF has its spring game Saturday.

Losing any player obviously hurts, but Grissom has the most starting experience of all the tackles on the team. Though line is a position with depth, Luke Sager, Elkino Watson and Todd Chandler don't have much in the way of extensive game experience. Grissom was having a terrific spring, too, so we will just have to wait and see how long he is going to be out.

Grissom's injury marks the second on the defensive line in a week. Backup end Anthony Hill tore his ACL last week, and there is no timetable for his return.
