With the Bengals getting knocked out of the playoffs on Sunday, it opened the door for their coaches to be pursued by other teams, and that began on Monday, when the Redskins asked permission to interview defensive coordinator Mike Zimmer and offensive coordinator Jay Gruden, a source told Mark Maske of The Washington Post.

It is unclear if Zimmer and Gruden have accepted interviews, and if they have, when they would occur. Zimmer reportedly will also interview with the Vikings.

Zimmer, 57, has been an NFL assistant since 1994, when he was hired as the defensive backs coach of the Cowboys. He was Dallas' defensive coordinator from 2000 to 2006 and served in the same role for the Falcons in 2007 before taking the job in Cincinnati in 2008. He hasn't been a head coach at any level.

Gruden, the younger brother of Super Bowl-winning coach Jon Gruden, has been with the Bengals since 2011. Three other teams — the Lions, Vikings and Titans — have contacted the Bengals about him.
