New Orleans, La.- According to NFL.com and NFL Network's Michael Lombardi, the league voided Payton's contract extension, which he received in 2011, because of concerns about the language in it.
NFL.com reports the Saints and the NFL discussed the issue many times, but they never found a resolution.
"Our office has made no determination on Sean Payton's contract status with the Saints for next year," NFL spokesman Greg Aiello said in a statement given to Rapoport. "All contracts between clubs and their employees must be approved by the commissioner, and we do not comment on specific terms of individual contracts. Any comment regarding the matter should come from Coach Payton and the Saints."
