Virginia quarterback Phillip Sims (14) hands the ball off to running back Kevin Parks (25) during the second half of an NCAA college football game at Scott stadium in Charlottesville, Va., Saturday, Sept. 29, 2012. Sims replaced starter Michael Rocco who threw three interceptions. Louisiana Tech won the game 44-38.

Virginia quarterback Phillips Sims says he's not Superman.

The Alabama transfer and likely starter Saturday when the struggling Cavaliers (2-3) play at Duke (4-1) says he's only being asked to do what he can within the framework of the team's offense.

Coach Mike London says Sims "will more than likely be the starter for us." The coach has said the holdup in making it official is ensuring the leg injury Sims suffered last week has sufficiently healed. London says Sims has moved well in practice, and Sims says the injury is no big deal.

The Cavaliers have lost three straight, and Michael Rocco has thrown five interceptions in the past two games — eight on the season.

Sims has five TD tosses and no interceptions in a backup role.
