The cornerback from Decatur High, who had looked impressive in preseason drills, suffered a cracked fifth metarasal in Saturday's practice.
"We are not sure how long he will be out of practice," says head coach Tommy Tuberville. "He will be checked out by Dr. (James) Andrews on Wednesday and we should know more about it then."
Jerraud Powers is shown in an August practice.
Tuberville says the quick, five-foot-nine, 175-pound true freshman was off to a good start in his first month as an Auburn football player.
The loss is not expected to affect secondary coach David Gibbs' playing rotation at cornerback for the opening game with Georgia Tech with older players such as David Irons, Montae Pitts, Patrick Lee, Jonathan Wilhite and Lorenzo Ferguson competing for the first and second team spots.
Pitts, a junior returning starter, is facing a major challenge from Lee, a sophomore who is playing by far his best football at AU. He began preseason no better than third on the depth chart, but worked with the first team in Saturday's practice.
