The All-America running back was facing misdemeanor assault and disorderly conduct charges stemming from an incident with his ex-girlfriend in December. On Friday, the Tuscon City Prosecutors Office issued a statement saying it was dismissing all charges against Carey.
Carey finished his sophomore season as the nation's leading rusher with 1,929 yards and set a school record with 23 touchdowns. He figures to be a key piece of the Wildcats' offense this fall, particularly with the team's leading receiver, Austin Hill, suffering a torn ACL during spring practice.
The Wildcats went 8-5 in 2012, the first season under Rich Rodriguez, finishing the year with a thrilling 49-48 comeback win against Nevada in the New Mexico Bowl.
