The Boilermakers (4-3, 3-1 Big Ten) won their fourth straight overall, their second in a row over a ranked team and pulled off their biggest upset since taking down then-No. 2 Ohio State 28-23 on Oct. 6, 1984. Purdue also set a school record for points scored against the Buckeyes, besting the previous mark of 41 in 1967.

Mistake-prone Ohio State (7-1, 4-1) had its 12-game winning streak snapped, fell out of the Big Ten East lead behind rival Michigan and now must fight away its way back into playoff position.

Blough outplayed Heisman Trophy candidate Dwayne Haskins Jr. on a night the Buckeyes didn’t reach the end zone until early in the fourth quarter.
