Oklahoma moved up to No. 2 in The Associated Press college football poll behind Alabama after the Sooners scored the most impressive victory of Week 2.

Three of the top six teams from last week defeated other ranked teams Saturday, creating an early shake-up near the top of the AP Top 25. The Sooners jumped three spots after winning 31-16 at Ohio State. The last time the Sooners were this close to being No. 1 was 2011.

The Buckeyes slipped from No. 2 to eighth.

Clemson held its spot at No. 3 after beating Auburn, and Southern California moved up two places to sixth following a victory against Stanford. Penn State is No. 5.

The Crimson Tide received 59 first-place votes. Oklahoma has two and Clemson one.

The Buckeyes have their lowest ranking since November 2014. Ohio State hopes this season takes a similar path.

In 2014, the Buckeyes lost at home to Virginia Tech and fell from No. 8 to No. 22 in the rankings. The Buckeyes did not lose again and won the national championship in Urban Meyer’s third season as coach in Columbus.

The Buckeyes did extend their streak of 41 polls ranked in the top 10, which dates back to the Nov. 9, 2014.

Notre Dame’s stay in the Top 25 lasted one week. The Fighting Irish lost 20-19 at home to Georgia, which moved up two spots to No. 13. The Irish were the only team to fall out of the rankings.

EAST CAROLINA: Pirates Coach Scottie Montgomery says defensive coordinator Kenwick Thompson has been reassigned within the football program and will no longer coach, and defensive line coach Robert Prunty has replaced him immediately.

Montgomery announced the changes a day after a 56-20 loss at West Virginia in which the Pirates (0-2) fell behind 49-3 at halftime and allowed 619 total yards.

NOTRE DAME: As Saturday night turned into Sunday morning following Georgia’s 20-19 victory over Notre Dame, Fighting Irish offensive lineman Mike McGlinchey took the blame.

“It’s awful, absolutely awful … it came down to execution at the end and I blew it,” said McGlinchey, a 6-foot-8, 315-pound left tackle who turned down the NFL to try to help Notre Dame rebound from a 4-8 season.

McGlinchey held himself responsible for missing the block that led to Georgia linebacker Davin Bellamy’s sack of quarterback Brandon Wimbush and linebacker Lorenzo Carter’s fumble recovery that ended Notre Dame’s chance of rallying past the No. 13 Bulldogs.
