IU was ranked No. 10 in the Associated Press Top 25 Poll this week after defeating then-No.23 Michigan 38-21 on Saturday.
The Hoosiers were also ranked No. 10 in the Amway Coaches Poll.
IU moved past the University of Georgia, the University of Oregon and Wisconsin in the rankings.
The Hoosiers' No. 10 ranking is the highest the team has been ranked since they were ranked No. 10 in 1969.
The victory was the first over the Wolverines since 1987. This season is also the first time IU started 3-0 in the Big Ten since 1988.
IU will play Michigan State next Saturday at noon in East Lansing, Michigan.
