Former Nebraska head coach Bo Pelini could be making a return to the FBS level of college football, this time as a defensive coordinator.

On Monday, FootballScoop reported that Pelini is a candidate to fill the vacancy at LSU for defensive coordinator. The position became available when Dave Aranda became the head coach at Baylor. Pelini was once the defensive coordinator in Baton Rouge from 2005-07 under Les Miles.

Pelini was on the staff for LSU’s 2007 national championship run.

Currently, Pelini serves as the head coach at Youngstown State, where he’s been since 2015. In five seasons with the Penguins, Pelini has accumulated a 33-28 record and made one FCS Playoff appearance (2016). That year Youngstown State made it to the FCS Championship Game, where the Penguins were defeated 28-14 by James Madison.

Before Youngstown State, Pelini was the head coach at Nebraska from 2008-14. He enjoyed success while in Lincoln, compiling a 67-27 record and taking his team to the post season in all seven years. His Huskers teams won nine games or more every year.

Pelini was fired from Nebraska following a 9-3 season in 2014.

LSU is coming off a perfect 15-0 season, winning the national title. The Tigers defeated Oklahoma in the Peach Bowl and Clemson in the College Football Playoff National Championship Game.
