Auburn head coach Gene Chizik

AUBURN, Ala. (AP) — Auburn football coach Gene Chizik has received a new contract nearly doubling his salary after leading the Tigers to a national championship.

Auburn announced a deal Friday worth $3.5 million a year through 2015. Chizik could make up to $4.5 million with incentives.

He made $2.1 million in salary last season, but received another $1.3 million in bonuses after the Tigers went unbeaten and won the national title.

Chizik is 22-5 in two years with Auburn since a hiring that was criticized because of a losing record at Iowa State.

He has also managed to keep his staff mostly intact. Only defensive line coach Tracy Rocker has left during his tenure.
