Big Ten athletic directors met with commissioner Tony Petitti on a video call Thursday without Michigan athletic director Warde Manuel present, and sources told ESPN the call about Michigan's alleged sign-stealing operation took on a distinctly different tenor than when they met a week ago.
Sources told ESPN that the athletic directors left the call with the notion than Petitti is taking the Big Ten's purview over the allegations more seriously than previously.
While no potential punishments were discussed, Petitti acknowledged speaking with the NCAA about its investigation, although he refused to divulge any details of that conversation, sources said.
