COLUMBUS, Ohio (WCMH) — A 31-7 win over Northwestern at Wrigley Field has kept the Buckeyes high in the latest rankings and sets up another top-five clash.

Ohio State (9-1, 6-1) is ranked No. 2 in the nation for a second consecutive week in the Associated Press poll and USA Today coaches poll, remaining only behind the top-ranked Oregon Ducks, who beat the Buckeyes in October. Slightly below the Buckeyes is their next opponent, No. 5 Indiana, who enters Saturday’s noon game in Columbus undefeated.

This will be the Buckeyes’ third top-five matchup this season after the October loss to Oregon and November win over Penn State. This is the first time in program history the Hoosiers are playing in a top-five game. Saturday’s contest is in theory a Big Ten semifinal with the winner likely securing a place in the Big Ten championship game against Oregon, barring any upsets.

Elsewhere in the poll, the top-ten saw changes after Georgia’s bounce back win over Tennessee 31-17 and Big 12 leaders BYU losing for the first time this season 17-13 at home against Kansas. The Bulldogs are back in the top-ten and joined by Mississippi, who rejoin this week. BYU’s loss sent them plummeting down to No. 14.

While the Buckeyes-Hoosiers game will own the headlines on Saturday, another Week 13 all-ranked game to keep tabs on is No. 18 Army taking on No. 6 Notre Dame at 7 p.m. on NBC4. The Fighting Irish seem poised for an at-large playoff spot and look to hand the Black Knights their first loss of the season.

The Buckeyes are expected to keep their No. 2 place in the next College Football Playoff rankings on Tuesday night. We can expect shake-ups in the potential bracket after BYU and Tennessee’s losses, which will shuffle the seedings significantly.

Using the Week 13 rankings, the Buckeyes would host BYU in a first round playoff game on Dec. 20 or Dec. 21. The winner would face No. 4 seed Boise State in the Fiesta Bowl on New Year’s Eve.
