4 Ala. football players arrested after robberies

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.

All four students were indefinitely suspended by coach Nick Saban.

Pettway and Hayes were charged with second-degree robbery. Williams was charged with fraudulent use of a credit card and second-degree robbery. Calloway was charged with fraudulent use of a credit card. Williams was released on $65,000 bond, while Hayes and Pettway were released on $60,000 bond each. Calloway was released on $5,000 bond.

"This behavior is unacceptable for any student-athlete at the University of Alabama and not representative of our football program," Saban said in a news release.

All four players were backups last season for Alabama, which has won two straight national titles and three of the past four. Williams didn't play in 2012. But he was one of the nation's top prospects the previous year and moved from receiver to safety.
