With Ohio State beating Indiana and Notre Dame blowing out Army, Oregon stands alone as the last undefeated team in the country. A trip to the Big Ten championship game is secured. Either the Buckeyes or Penn State will be on the other side. A slot in the inaugural 12-team College Football Playoff is all but assured.

Indiana dropped from No. 5 to No. 10 following its first loss, 38-15 loss at Ohio State. The Buckeyes would play Oregon in the Big Ten championship game if they beat Michigan for the first time in four years this Saturday.

In the new, expanded 12-team playoff, the five highest-ranked conference champions will make the field along with the next seven highest-ranked teams. The four highest-ranked conference champions will be awarded first-round byes, with the other eight teams meeting at the campus sites of the Nos. 5-8 seeds.
