College football rankings after Week 5: Updated Coaches Poll. AP Top 25 for Big Ten

Week 5 of the 2026 college football season produced a number of notable results in the Big Ten.

In the highest-profile matchup of the day in the conference, No. 6 Ohio State went on the road and knocked off No. 14 Iowa, 31-14, thanks to another ridiculous performance from wide receiver Jeremiah Smith, who caught 11 passes for 206 yards and two touchdowns.

No. 24 Michigan's struggles in its first season under coach Kyle Whittingham continued, with the Wolverines falling on the road to Minnesota, 20-14, in a game in which Bryce Underwood threw for a season-low 101 yards, no touchdowns and two interceptions.
