Allen served as the Saints’ secondary coach when the team won the Super Bowl back in 2009.

Lions defensive coordinator Aaron Glenn, Chiefs offensive coordinator Eric Bieniemy and former Dolphins head coach Brian Flores were other known candidates for the Saints job, but the team decided to go with Allen, who’s been with New Orleans since 2015.

It will also be Allen’s second stint as a head coach. He led the then-Oakland Raiders for two-plus seasons from 2012-2014, and he finished with an 8-28 record over that span.

With Allen in the Saints vacancy, all nine NFL head coaching gigs from the end of the regular season have been filled.

Allen left the Saints in 2011 to become the Broncos defensive coordinator before taking the head coaching position with the Raiders one year later. Allen was fired by the Raiders four games into the 2014 season and returned to New Orleans as a senior defensive assistant in 2015.
