Ohio State's players, coaches and fans were not at all happy with the officiating on Penn State's most-recent drive.
One penalty call in particular had Buckeyes fans furious.
An Ohio State defensive back was called for a pass interference play on an underthrown ball by Penn State quarterback Trace McSorley.
Some former Buckeyes standouts took to Twitter to trash the call.
"Horrible egregious call," tweeted former star Ohio State cornerback Eli Apple.
"Those refs ought to be ashamed," tweeted former Ohio State star linebacker Joshua Perry.
The penalty didn't end up costing Ohio State, though. The Buckeyes stopped Penn State on fourth down to get the ball back.
It's now Ohio State 14, Penn State 13 as we begin the fourth quarter.
