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 Louisiana State University and Oregon. Florida State moved into a tie for fifth with Oklahoma. Georgia is No. 7, South Carolina is No. 8 and Clemson is No. 11.
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 Brigham Young.
It won’t get any easier for the Razorbacks, who face the Crimson Tide this week. Coach John L. Smith said Wilson’s prognosis is good heading into that game.
