Shortly after the investigation came to light, Williams was accused of running similar schemes while he was defensive coordinator of the Houston Oilers/Tennessee Titans and Washington Redskins, and head coach of the Buffalo Bills. The league suspended Williams indefinitely and Payton for one year, and suspended the Saints' general manager and another assistant for parts of the 2012 season. Jonathan Vilma, a Saints player who had a major role in the scheme and reportedly offered a $10,000 bounty on Brett Favre, was suspended for the entire season, and three other players were suspended for parts of the season. However, in September 2012, an arbitrator overturned the suspensions of the players involved in the affair.
