Sources - Michigan staffer bought tickets at 10 Big Ten schools - ESPN

Connor Stalions, the suspended Michigan staffer at the center of the NCAA's sign-stealing probe, purchased tickets in his own name for more than 30 games over the last three years at 11 different Big Ten schools, sources at 11 different league schools told ESPN.

The scope of the University of Michigan's alleged sign-stealing operation includes both video evidence of electronics prohibited by the NCAA to steal signs and a significant paper trail, sources told ESPN. Stalions forwarded the tickets he bought to at least three different people in different areas of the country, sources say, which hints at the breadth of the operation.

The NCAA is expected to receive video evidence this week of illegal technology used in scouting tied to tickets purchased by Stalions, according to sources. An opposing Big Ten school looked up in-stadium surveillance video from a game earlier this year, and sources said the person in the seat of the ticket purchased by Stalions held his smart phone up and appeared to film the home team's sideline the entire game.

Sources confirmed to ESPN that Stalions purchased tickets on both sides of the stadium — across from each bench — for Ohio State's game with Penn State on Saturday. Michigan plays both teams in upcoming weeks. According to sources, the tickets purchased by Stalions were not used on Saturday. Stalions' name emerged publicly in an ESPN story on Friday. He was suspended with pay by Michigan.

None of the tickets that the 11 schools told ESPN about involved Michigan as an opponent, per sources. The games involved either one or both of the teams that the Wolverines were playing later that year, according to sources.

Stalions did not respond to ESPN's request for comment. Michigan did not
