IU was ranked No. 13 in this week’s Associated Press Top 25 poll, its highest ranking since Oct. 27, 1987.
The Hoosiers were also ranked No. 13 in the Amway Coaches Poll, its highest ranking since 1993.
IU moved up in the polls after its 37-21 victory over Rutgers on Saturday.
IU moved ahead of Michigan, the University of North Carolina, Kansas State University and Oklahoma State University after all four schools lost.
This week will be the first time IU is ranked higher than Michigan in a head-to-head matchup since Oct. 22, 1988. The Hoosiers lost that game 31-6 and have not beat the Wolverines since.
IU is 2-0 and will face Michigan at noon Saturday at home.
