Lane Kiffin and Co. are cruising through Spring Camp, Week 4 begins as position battles continue taking shape.

For now, both quarterbacks are earning first-team reps as Arizona State transfer and presumed starter Sam Leavitt sits out the rest of spring practices as he recovers from a foot injury. His absence, therefore, has created a competition to see who his primary backup will be heading into the fall.

Defensive end Gabrial Reliford, who tore his ACL earlier this spring, did not practice, as well as freshman offensive lineman Solomon Thomas, who was seen on a scooter on the sideline. Place kicker Aidan Corbello was seen on the sideline, not going through practice.
