No. 14 Ohio State (21-7, 11-5 Big Ten) travels to play second-ranked Indiana (25-4, 13-3) on Tuesday night as the Big Ten's wacky regular-season starts to wind down.
The Hoosiers already have captured a share of the conference title. To win it outright for the first time since 1993, they need to beat the Buckeyes or win at No. 7 Michigan on Sunday.
Meanwhile, Ohio State, Michigan, 22nd-ranked Wisconsin and No. 10 Michigan State still have a shot at getting a piece of the regular season championship.
Just a year ago the Big Ten leader lost at home in the final week, opening the door to a three-way tie. The Ohio State-Indiana game could settle things or leave the title in doubt.
