MONTGOMERY, Ala. (AP) — Three University of Alabama football players have been charged with knocking students unconscious and stealing their wallets, while a fourth player has been charged with using a stolen debit card, officials said Tuesday.

Linebacker Tyler Hayes, 18, and safety Eddie Williams, 20, confessed to robbing a student who was punched in the head and face and kicked in the ribs and back early Monday morning, according to court documents. Williams said D.J. Pettway, 20, a defensive lineman, and Hayes waited in a nearby vehicle about an hour later while he knocked out and robbed another student. Williams and Hayes both admitted to their involvement, according to the documents.

Williams and running back Brent Calloway, 20, both admitted to using a stolen credit card to buy snacks from vending machines inside a dormitory, the documents said.
