From Fox News:

Indiana hung on to win the Big 10 title 13-10 on Saturday after Ohio State kicker Jayden Fielding missed a 27-yard field goal in the final minutes. The victory marks the Hoosiers’ first outright conference championship since 1945, after a shared win in 1967.
The Hoosiers were four-point underdogs going into the game against the defending national champions, with the top seed in the College Football Playoff on the line. Now, before the playoffs even start, Indiana has arguably clinched its most successful season in the modern era. “I want to give all the glory to God. We were never supposed to be in this position, but by the glory of God, the great coaches, the great teammates, everybody around us, we were able to pull this off,” Indiana quarterback Fernandeo Mendoza told Fox Sports after the game.
