ANN ARBOR, Mich. >> Connor Stalions, the former Michigan staffer at the center of sign-stealing investigation by the NCAA, did not file any expense reports during the 17 months he was formally employed by the football program, according to the school.

The Associated Press filed a Freedom of Information Act request for Stalions’ expense reports while he was employed from May 2022 through Nov. 3, 2023. There are no responsive records, Patricia Sellinger, chief freedom of information officer at the school, replied in an email sent Wednesday.

The NCAA has documented plans and budget information outlining the scouting scheme of Michigan opponents and the Big Ten said has received those materials. The NCAA also shared evidence with the Big Ten and the university that showed Stalions purchased tickets to games and had people sit in those seats to obtain video of the sideline signals.

Jim Harbaugh was suspended for the final three games of the regular season by the Big Ten, which said it didn’t have evidence that the coach knew about the scheme. He missed last week’s win over then-No. 9 Penn State.

A judge scheduled a hearing for Friday to hear the school’s attempt to at least temporarily lift the Big Ten’s penalty and allow Harbaugh to coach the second-ranked Wolverines (10-0, 7-0 Big Ten, No. 3 CFP) against Maryland (6-4, 3-4) on Saturday and against rival Ohio State next week.

Stalions had been employed by Michigan as a recruiting analyst an annual salary of approximately $55,000. He resigned earlier this month, two weeks after he was suspended by the university when the NCAA and Big Ten Conference acknowledged the school was being investigated.

The NCAA does not not directly ban the stealing of signs, but there are rules against using electronic equipment to record an opponent’s signals and in-person, advanced scouting of future opponents in season. There are also rules against unsportsmanlike or unethical activities by coaches.

Stalions, who has been identified on social media accounts as a graduate of the Naval Academy and a longtime Michigan football fan, has not commented publicly. He said through his lawyer that neither Harbaugh nor any member of his coaching staff told anyone to break any rules or were aware of improper conduct when it came to scouting.

Harbaugh has denied knowledge of any alleged scouting scheme in his program.
