Andy Ludwig is taking over as offensive coordinator at Vanderbilt after two seasons in that role at Wisconsin.

Vanderbilt announced the hire Monday in a university release that also indicated coach Derek Mason would call the Commodores' defensive alignments next season.

Ludwig also was quarterbacks coach the past two years at Wisconsin working for Gary Andersen, who left last month to take over at Oregon State.

Former offensive coordinator Karl Dorrell and defensive coordinator David Kotulski were fired after the Commodores went 3-9 this fall.
