NEW YORK (AP) — Winning the biggest game of college football’s opening weekend boosted LSU to No. 2 in The Associated Press Top 25.

No. 1 Oklahoma held on to the top spot in the first regular-season rankings, while the Tigers used their 40-27 victory against Oregon to jump rival Alabama, which slipped to No. 3.

Mississippi State, coming off a 59-14 throttling of Memphis, moved up to No. 16. The Bulldogs are scheduled to play unranked Auburn on Saturday.

Boise State moved up a notch to No. 4 after its impressive 35-21 win against Georgia. Florida State moved up to No. 5.

Oregon dropped nine spots to No. 13 and defending national champion Auburn, which started the season at No. 23, fell out of the Top 25 after needing a late rally to beat Utah State at home. Notre Dame also dropped out.

Moving into the rankings were No. 20 Baylor, No. 22 South Florida, No. 23 Penn State and No. 24 Texas.
