(CBS/KCBS/AP) Former USC quarterback Mitch Mustain is in custody Wednesday after being arrested for allegedly selling prescription drugs.
Mustain, 22, was arrested at about 8 p.m. Tuesday in the San Fernando Valley by LAPD West Valley Station detectives.
He was booked for a felony and was released after posting $30,000 bail, according to CBS affiliate KCBS.
Mustain became a backup quarterback for the Trojans after transferring to USC from Arkansas in 2007. He started in last season's game against Notre Dame when Matt Barkley was injured.
