This Saturday night’s game against Ohio State is Penn State’s biggest test so far.

And it may turn out to be its toughest game of the season.

And ESPN’s College GameDay thinks so too.

Kirk Herbstreit, Lee Corso and Rece Davis will be in Happy Valley Saturday morning before Penn State’s prime-time, White-Out game.

GameDay, making its seventh trip to State College, begins at 9 a.m. on ESPN. The game kicks off at Beaver Stadium at 7:30 p.m. on ABC with Herbstreit and Chris Fowler on the call.

Corso will choose headgear between the No. 10 Nittany Lions or No. Buckeyes, a pair of undefeated teams that posted a combined 440-146 scoring margin to start the season.

This matchup — one between coaches James Franklin and Urban Meyer and quarterbacks Trace McSorley and Dwayne Haskins — was circled a long time ago by Penn State fans. Without another premiere game on the Week 5 slate, it made total sense to have GameDay in Happy Valley.
