Auburn fired coach Bryan Harsin on Monday after less than two seasons in charge.
The decision was made to dismiss him after Saturday's 41-27 loss to Arkansas, dropping the Tigers to 3-5 on the season and 1-4 in the Southeastern Conference.
That setback was the fourth straight loss for Auburn, which included a 42-10 drubbing to top-ranked Georgia on October 8.
"Auburn University has decided to make a change in the leadership of the Auburn University football programme," the school said in a brief statement announcing the move.
''Auburn will begin an immediate search for a coach that will return the Auburn programme to a place where it is consistently competing at the highest levels and representing the winning tradition that is Auburn football."
Auburn hired Harsin in December 2020 after he went 69-19 in seven seasons at Boise State, leading the Broncos to four Mountain West titles and three bowl victories.
He was unable to find similar success at Auburn, however, going 6-7 in his first season at the helm, with a 3-5 record in the SEC.
The Tigers also struggled mightily against top-tier competition, going 2-8 against ranked opponents in the 45-year-old's time in charge.
Auburn gave Harsin a six-year, $31.5million contract, and the school still owes him more than $15m as part of his buyout
