Two more Bulls returned to the practice field Wednesday as junior cornerback Theo Wilson resolved his academic issues and freshman tight end Andreas Shields was cleared by the NCAA Clearinghouse. With two days until USF's season opener against Tennessee-Martin, the Bulls have only one scholarship player -- freshman cornerback George Baker -- still awaiting NCAA approval.

USF coach Jim Leavitt said he expects Wilson to play Saturday and said the former Dunedin quarterback could make an impact at cornerback or as a new option on punt returns. Shields is expected to redshirt.

-- Leavitt announced his senior captains for Saturday's game: running back Ben Williams, center Jake Griffin, and linebackers Tyrone McKenzie and Brouce Mompremier. Leavitt said he'll likely rotate captains from game to game throughout the season.

-- Sophomore Aston Samuels, recovering from a broken shoulder socket he suffered in spring drills, is still far away from a healthy return, but he was working informally with USF's receivers Wednesday. Samuels had worked at running back in his first two seasons, but Leavitt said he'll be a "multi-purpose" player when he returns, though that might not be until next year.

-- Defensive tackle Sampson Genus worked at full strength for the second day in a row, showing good progress after being held out with an injured ankle. Leavitt said Genus is "fine" and defensive ends coach Kevin Patrick said Genus, sophomore Terrell McClain and junior Aaron Harris will all see significant action Saturday.

-- Lose a walk-on, add a walk-on: Defensive tackle Lou Alguadich of Fort Myers lasted only one day as a walk-on, so USF added Rony DeLisca, a defensive end from Wharton. DeLisca is the third USF walk-on from Wharton, joining running back Joel Miller and linebacker LaDre Watkins.
