AUBURN, Alabama -- Auburn's search for a new football coach may be focused on three former assistants at the school who, at least through their representatives, have not cut off potential communication with the university.

Auburn continues to gauge the interest of former Arkansas coach Bobby Petrino, Florida State coach Jimbo Fisher and Arkansas State coach Gus Malzahn.

Also, TCU coach Gary Patterson remains a player in the search.
