TAMPA - USF freshman point guard Anthony Collins, who missed the second half of Thursday's win at Villanova after hitting his head on the court during a layup attempt, will undergo more tests Saturday to determine how quickly he can return to play.

Collins flew back to Tampa with the team on Friday, writing on Twitter.com that he was "feeling much better." He hit his head on the court six minutes into Thursday's 74-57 win at Villanova, and while he returned after the injury, team trainers held him out of the second half.

Collins has been the catalyst in USF's 9-6 record and 2-1 start to Big East play, getting 10 assists and the winning layup in USF's home win against Rutgers. Sophomore Blake Nash stepped up well in Collins' absence Thursday, finishing with 12 points, six assists and just one turnover in 28 minutes off the bench.

The Bulls have only two point guards on roster, as sophomore Lavonte Dority opted to transfer at the semester break after being limited to sparse playing time after Collins' emergence. USF plays Tuesday at Notre Dame, then returns home to play Seton Hall on Friday night.
