Big Ten Commissioner Tony Petitti sent a letter to the NCAA Committee on Infractions suggesting that Michigan's football program should not face more sanctions stemming from a sign-stealing scheme, according to a person familiar with the situation.

The Big Ten confirmed to ESPN that Petitti sent the letter and said he would have attended in person but was recovering at the time from hip replacement surgery. The NCAA and Michigan are prohibited from commenting on a pending case. Petitti declined comment through a league spokesperson.
