Arizona State quarterback Taylor Kelly is not expected to play against UCLA on Sept. 25 due to a foot injury, according to a source.
Mike Bercovici will be prepared to start at quarterback, the source said. The Sun Devils' bye week will give them extra time to provide first-team reps to Bercovici, who may also have to start against USC the following week.
Kelly, a senior, is one of seven Sun Devil quarterbacks to pass for more than 6,000 career yards. He tossed 57 touchdowns the past two seasons and set the school record for completion percentage last season.
Bercovici, a junior, has a strong arm and quick release but has limited game experience.
