(RollTide.com) TUSCALOOSA, Ala. - The University of Alabama football team worked for two hours in shells (helmets, shoulder pads, shorts) on Friday afternoon at the Thomas-Drew Practice Fields.

At the conclusion of Friday's practice, head coach Nick Saban announced to the team that walk-ons Truett Harris (Sr., TE, Brentwood, Tenn.), Brandon Moore (Sr., TE, Cincinnati, Ohio) and Levi Wallace (Jr., DB, Tucson, Ariz.) have been awarded scholarships. The three join fellow former walk-on Jamey Mosley (Soph., LB, Mobile, Ala.), who was awarded a scholarship earlier in training camp.

The 23rd session of fall camp lasted nearly two hours with the team continuing to drill in preparation for the season opener against the 20th-ranked USC Trojans. The two storied programs will kick off the season in Arlington, Texas, at AT&T Stadium for the AdvoCare Classic. The Sept. 3 contest is scheduled for a 7 p.m. CT kickoff on ABC with Chris Fowler, Kirk Herbstreit and Samantha Ponder on the call.

Tomorrow's session is set for a 3:40 p.m. CT start before the Crimson Tide takes Sunday off. Following the break, the team will begin its game week schedule of practices on Monday before heading to Arlington on Friday afternoon.
