Arkansas has taken the second-largest fall out of the AP college football poll, dropping from eighth to unranked after losing to Louisiana-Monroe.
The Razorbacks were upset 34-31 in overtime after losing quarterback Tyler Wilson to an injury. The only team to take a more drastic fall from the poll was Michigan in 2007. The Wolverines opened the season at No. 5 and dropped out after a Week 1 loss to Appalachian State.
Alabama remains No. 1. Southern California is No. 2, followed by LSU and Oregon. Florida State moved into a tie for fifth with Oklahoma. Georgia is No. 7.
Arkansas was one of four teams to drop out after losses, along with Nebraska, Wisconsin and Oklahoma State.
Moving in were UCLA, Tennessee, Arizona and BYU.
