Auburn is looking to bounce back from its second loss of the season, while Arkansas still searches for its first SEC victory when the teams collide Saturday in Fayetteville, Ark.
The No. 21 Tigers (5-2, 3-1 SEC) plummeted 11 spots in the poll after last week's 27-23 loss at LSU, when Auburn blew a 20-0 lead early in the second quarter.
Arkansas, meanwhile, is 0-3 in conference play and coming off a 41-9 road loss to No. 1 Alabama.
