LSU’s upset of then-No. 3 ranked Ole Miss on Saturday night has the Tigers back inside the top 20.
The six-spot jump is the biggest of any team in either poll. LSU is also the highest-ranked two-loss team this week.
Still to come: the inaugural College Football Playoff rankings, which will be unveiled at 6:30 p.m. Tuesday on ESPN.
Ole Miss (7-1, 4-1) dropped four spots to No. 7 in the AP poll and six spots to No. 9 after going down in Tiger Stadium. The Tigers beat the Rebels 10-7 in a classic duel in front of a raucous and sold-out venue.
Fans stormed the field for the first time since a 2001 win over Auburn. LSU will likely suffer a fine from the Southeastern Conference for the field storming. A first offense is $5,000.
LSU has a bye this week before hosting No. 3 Alabama on Nov. 8.
An announcement on the kickoff time and TV network for that game is expected Monday. The game appears likely to be chosen by CBS for a 7 p.m. kickoff.
