ATLANTA (AP) — Georgia Tech's running back situation is more crisply defined than Georgia's four days before the annual battle for state bragging rights.

Coach Paul Johnson says he expects one of his top backs, Orwin Smith, to return from an injury to play for No. 25 Georgia Tech in Saturday's game. Smith missed last week's win over Duke.

Also Tuesday, Georgia coach Mark Richt says "there is a chance" leading rusher Isaiah Crowell will return from his left ankle injury. Richt hasn't decided if backup Carlton Thomas will return from his latest suspension.

Crowell had only two carries before leaving with the injury in No. 13 Georgia's difficult 19-10 win over Kentucky last week. The offense has been most productive with Crowell, a freshman who has 832 yards rushing.
