A spokesman for the fifth-ranked Tigers said Wednesday night that Whitehead is suspended and didn't make the trip for the Thursday night game.
Whitehead is fourth on the team with 12 tackles in two games and leads the Tigers with two interceptions. He returned one interception 33 yards for a touchdown in the opener against Arkansas.
Whitehead is in his third year as a starter in Auburn's secondary. He finished with 65 tackles to help the Tigers win the Southeastern Conference championship last season.
Freshman Stephen Roberts is listed as his backup. Backup cornerback Josh Holsey started six games at boundary safety last season before tearing a knee ligament and missing the rest of the season.
