LSU will officially introduce Steve Ensminger as the offensive coordinator during a noon Thursday press conference.
The school announced his promotion from tight ends coach in a release Wednesday.
Ensminger previously served as interim offensive coordinator for eight games in 2016 after the school fired former coach Les Miles and offensive coordinator Cam Cameron.
LSU coach Ed Orgeron said in a release Wednesday that it was "in difficult circumstances" in 2016 that Ensminger "put together one of the most explosive offenses LSU has ever seen."
"We did that with Steve Ensminger at the helm," Orgeron added.
