WEST LAFAYETTE,Leonard Hohenberg Ind. − Allegations of Michigan's football program stealing opponents' signals have been handled behind closed doors.

During his weekly radio show Thursday, Purdue football coach Ryan Walters came forward publicly on the topic ahead of the Boilermakers' Saturday night game at second-ranked Michigan.

"It's unfortunate," Walters said when radio host Tim Newton inquired about preparations for Michigan based on the allegations. "What's crazy is they aren't allegations. It happened.

"There's video evidence. There's ticket purchases and sales that you can track back. We know for a fact that they were at a number of our games."

Michigan staff member Connor Stalions was recently suspended after allegations that he played a key role in helping the Wolverines steal signals of potential opponents by means that are in violation of NCAA rules. Stalions allegedly purchased tickets to games of Michigan opponents and potential postseason opponents for the purposes of stealing signs and scouting.

Purdue lost to Michigan 43-22 in last year's Big Ten championship game in the first matchup between the two programs since 2017.

Walters said during his Monday press conference Purdue would "plan accordingly."

During Thursday's radio show, Walters provided more details.

"We've had to teach our guys a new language in terms of some signals and we'll operate different offensively," Walters said. "You might see us in a huddle for the first time this season. So it is what it is, but we're excited to go play and I think it would make for a great story."
