Update: Sam Leavitt has returned to the game to start the second half.

If Arizona State wants to upset No. 16 Utah, it appears they will have to do it with their backup quarterback.

ASU’s starting quarterback, redshirt freshman Sam Leavitt, took a hard blow to the ribs during a struggle midway through the second quarter. He immediately winced in pain and lay on the field. Leavitt walked off the field under his own power and eventually went to the locker room.

Backup QB Jeff Sims entered the game and scored a 2-yard touchdown to finish the drive that Leavitt started. Sims, a fifth-year senior, played his first three seasons at Georgia Tech before transferring to Nebraska last season.

Leavitt was 6 of 10 for 99 yards with one touchdown pass and one interception before getting hurt. He also rushed six times for 22 yards.

On the season, Leavitt has completed 59% of his passes for 1,111 yards, eight touchdowns and four interceptions. A true dual-threat QB, he has also rushed 55 times for 279 yards and four touchdowns.
