Bo Pelini is not expected to return for another season as LSU's defensive coordinator, a source confirmed to ESPN.
Pelini, a former head coach at Youngstown State and Nebraska, was brought on to coach LSU's defense in January, but ultimately failed to live up to expectations as the Tigers ranked next-to-last in the SEC in yards allowed per game.
Pelini has two years remaining on his contract and, according to The Baton Rouge Advocate, is owed a buyout of $5.2 million.
More changes are expected to occur on the LSU coaching staff throughout the course of the offseason, a source told ESPN.
