Les Miles has been fired by LSU as head coach with Ed Orgeron replacing him on an interim basis.

"Decisions like this are never easy ones to make," vice chancellor and director of athletics Joe Alleva said in a statement Sunday night. "Coach Miles has done a tremendous job here and he's been a great ambassador for our University, which makes this even more difficult.

"However, it's apparent in evaluating the program through the first month of the season that a change has to be made. Our commitment to excellence and competing at the highest level is unwavering, and our goals for the remainder of this season haven't changed. We have an obligation to our student-athletes to put them in the best position to have success on the football field each week and we have great confidence that coach Orgeron will do just that."

Miles was head coach for 12 years and survived a coup attempt last season.

Miles posted a 75-18 record (41-15 in SEC play) in his first seven seasons at LSU -- a stretch that included three SEC West titles, two SEC titles, a BCS championship and another title game appearance.
