After a six-year absence, Bo Pelini is expected to be making a return to the FBS ranks.

Monday, Ross Dellenger of Sports Illustrated reported that the former Nebraska and current Youngstown State head coach is expected to be making a return to Baton Rouge to join LSU’s staff as the defensive coordinator. He will be replacing Dave Aranda, who was named the head coach at Baylor earlier in the offseason.

Pelini did have one previous run at LSU, serving as the defensive coordinator under Les Miles from 2005-07. The Tigers won a national title in 2007, and Pelini quickly earned the job as the head coach at Nebraska the following year.

Per Dellenger, the deal is expected to pay Pelini around $2 million per year to run the defense.

From 2008-14, Pelini served as the head coach at Nebraska, winning nine games or more every season. He posted an overall record of 67-27 in seven seasons in Lincoln, leading the Huskers to a B1G title game appearance in 2012. Nebraska also played in the Big 12 Championship Game in 2009 and 2010, losing to Texas and Oklahoma by a combined four points.

Over the last five seasons, Pelini has been the head coach at Youngstown State (FCS). The Penguins are 33-28 in those five seasons, making a trip to the FCS National Championship Game in 2016. Youngstown State lost to James Madison.

LSU is coming off a 15-0 season, defeating Clemson in the championship game.
