Purdue coach Ryan Walters, whose team visits No. 3 Michigan on Saturday, said his school has evidence the Wolverines scouted the Boilermakers' games earlier this season.
The NCAA is investigating Michigan for off-campus scouting and signal-stealing. Michigan staff member Connor Stalions is at the center of the probe, according to sources, and has been suspended by the school with pay, pending the outcome of the investigation. Sources told ESPN's Pete Thamel and Mark Schlabach that there are records of Stalions purchasing tickets to games featuring 12 of Michigan's 13 Big Ten opponents over the past three years.
