NEW ORLEANS — New Orleans Saints coach Sean Payton, whose 15-year tenure with the club included its only Super Bowl championship and also a one-season suspension stemming from the NFL’s bounty investigation, is retiring from coaching.

Payton informed the team on Tuesday that he is leaving his first and only NFL head coaching job with a 152-89 regular-season record — and nine playoff appearances — in 15 seasons. The Saints won the NFL title in 2009.

The Saints made Payton a first-time head coach in 2006, when he oversaw a stunning turnaround in the franchise’s first season back in New Orleans following Hurricane Katrina. The club had been displaced from the city during the entire 2005 season, going 3-13.
