Jeremiah Masoli, who suffered a concussion in a 43-21 victory over Louisiana-Lafayette last weekend, practiced some on Tuesday but hasn't been cleared for contact.
The Rebels' other option at quarterback is sophomore Nathan Stanley, who completed six of 14 passes for 108 yards against Louisiana-Lafayette.
Coach Houston Nutt said he didn't have a deadline for making a decision about who will start. Masoli will continue to undergo tests throughout the week.
The Rebels must win three of their final four games to become bowl eligible.
