Mississippi's first loss of the season dropped the Rebels four spots in The Associated Press college football poll to No. 7 and left Mississippi State, Florida State, Alabama and Auburn in the top four as the College Football Playoff selection committee prepares its first rankings.
No. 1 Mississippi State (46 first-place votes) and No. 2 Florida State (14) are the only unbeaten team left in the Big Five conferences.
Alabama, which lost 23-17 at Ole Miss earlier this month, moved up a spot, as did No. 4 Auburn, No. 5 Oregon and No. 6 Notre Dame.
Ole Miss was beaten 10-7 at LSU on Saturday night. The Tigers moved up eight spots to No. 16, the largest jump after a weekend when only two ranked teams lost.
The first selection committee top 25 will be released Tuesday night. The pairings for the College Football Playoff will be revealed Dec. 7.
