Ross-Ade Stadium is going to be rocking next month.

Purdue announced Wednesday that its Oct. 23 game against No. 18 Wisconsin has sold out. That means some 57,000 people will be on hand for the matchup, which doesn’t even have a kickoff time yet.

The Boilermakers are 2-1 this season and are coming off a 27-13 loss at Notre Dame in Week 3. The Badgers, meanwhile, are 1-1 and are getting ready to face the No. 12-ranked Fighting Irish this week at Soldier Field in Chicago.

The capacity crowd could be in for quite a battle of the quarterbacks. Purdue’s Jack Plummer leads the B1G with 15 touchdown passes while Wisconsin’s Graham Mertz has completed 66.7% of his passes this season.

Kickoff time and TV listing for the game haven’t been announced yet. But one thing’s for sure: It’s going to be an awesome atmosphere.
