Baltimore Ravens offensive coordinator Jim Caldwell will interview Sunday for the Washington Redskins’ vacant head coaching job, according to the head of the diversity group that works with the NFL on hiring issues.

John Wooten, the chairman of the Fritz Pollard Alliance, said Saturday that Caldwell’s interview will take place Sunday morning at the Redskins’ headquarters in Ashburn.

“That’s set,” Wooten said.

Caldwell, the former head coach of the Indianapolis Colts, interviewed Friday with the Detroit Lions. He called the Lions job an excellent opportunity.

“This is an unusual situation because of the fact that you don’t typically walk into a place that has a talented quarterback, one of the best receivers in all the game and just a fine nucleus,” Caldwell said, according to the Lions’ Web site.

Many people in the league regard the Lions’ job as the most attractive head coaching position currently available because of the presence of quarterback Matthew Stafford, wide receiver Calvin Johnson and gifted players on the defensive line.

Caldwell worked with Peyton Manning as the Colts’ quarterbacks coach and led to the team to a Super Bowl appearance in his first season after succeeding Tony Dungy as the head coach. He was fired after going 2-14 in his third season in 2011, with Manning hurt.

According to Wooten, the Redskins wanted Caldwell to interview sooner but he didn’t want to rush through the interview process. Wooten said a report that Caldwell’s interview with the Redskins was done at midweek was incorrect.

Wooten said the Redskins are continuing to work to schedule an interview with New York Giants defensive coordinator Perry Fewell. The Redskins have received permission from the Giants to interview Fewell but a meeting has not been scheduled.

Five potential Redskins’ coaching candidates are coaching in NFL playoff games this weekend: offensive coordinators Greg Roman of San Francisco, Ken Whisenhunt of San Diego and Jay Gruden of Cincinnati, plus Bengals defensive coordinator Mike Zimmer and offensive assistant Hue Jackson. They could be interviewed by the Redskins in the coming week. The Fritz Pollard Alliance recommended to the Redskins that they consider Caldwell and Jackson.
