ATLANTA — Dave Wommack has been fired as Georgia Tech's defensive coordinator.

Georgia Tech announced on Friday that Wommack will not return for the 2010 season. Coach Paul Johnson says he and Wommack "both agreed" a change was needed after Georgia Tech ranked 54th in the nation in total defense and 56th in scoring defense.

The Yellow Jackets finished 11-3 and No. 13 but had struggles much of the season on defense. Georgia Tech allowed 24.8 points per game even when helped by the Yellow Jackets' ball-control spread option offense.

Georgia Tech allowed 30 or more points in six games this season.
