Family, friends and teammates of Keeley Dorsey, the football player who died last week, can commemorate his life during a memorial service on campus today at 4 p.m. at the Corral in the Sun Dome. Dorsey, 19, died during a routine conditioning workout at USF’s Athletic Facility on Jan. 17. He was a freshman running back for the Bulls. On Tuesday, Dorsey’s parents said they weren’t aware of any pre-existing medical problems that could have caused the sudden death.
