Dyer won't play in the Dec. 30 game against Georgia and his career was over. A former BCS title game MVP while at Auburn, Dyer had 154 carries for 704 yards and seven touchdowns in his injury-plagued two seasons with the Cardinals.
Dyer missed the first three games of this season with an injury, but played in the final nine and was the second-leading rusher on the team.
The native of Little Rock, Ark., rushed for 481 yards and five touchdowns this season. He rushed for 173 yards and a score versus NC State and 134 yards and three touchdowns against Florida State.
Sophomore Brandon Radcliff, the team's leading rusher, is expected to get a bulk of the carries against Georgia. Dominique Brown and L.J. Scott are the two other running backs still left on the roster.
The Cardinals leave for Charlotte, N.C., on Wednesday and will practice on Christmas morning for the first time at the bowl site.
