Add Ravens quarterback coach Rick Dennison to the list of potential candidates to replace John Fox in Denver.

Dennison is among the "early candidates" the Broncos are expected to pursue, according to the Denver Post's Mike Klis. During his playing days, Dennison played in three Super Bowls with Denver (XXI, XXII, and XXIV) before going on to join the team's coaching staff in 1995.

Dennison coached at various positions—including offensive coordinator—for the Broncos for fourteen years before joining the Texans in 2010, where he coached until 2013. In 2014, Dennison coached quarterbacks in Baltimore.

Here's an updated summary of Denver's six candidates:

Rick Dennison - he was a candidate in 2011 when Denver was seeking a coach, and Klis expects that he will be again. There have been no reports yet on Denver formally asking permission to interview him.

Gary Kubiak - he told the Ravens that he plans to stay in Baltimore, but John Elway seemingly hopes to pry him away. Denver plans to request an interview with Kubiak, per multiple reports.

Dan Quinn - he is the hottest head coach candidate, but teams may have to wait several weeks to talk to him if Seattle makes it back to the Super Bowl. Denver wants to interview him, per multiple reports.

Teryl Austin - he has been praised for being a great in-game tactician, and he's available for interviews. Denver has already asked permission to interview him, per ESPN's Adam Schefter.

Adam Gase - he had a long interview with the 49ers today, but he is staying in Denver tonight to talk with the Broncos, per The Sacramento Bee's Matt Barrows. Gase is considered by many to be the favorite to land in San Francisco, but he is also a candidate in Denver, according to John Elway.

When considering Denver's candidates, CBS4 reporter Vic Lombardi says one key thing should be kept in mind:

As the Broncos conduct their search for a new head coach, keep three words in mind: Super Bowl pedigree. — Vic Lombardi (@VicLombardi) January 14, 2015

Elway has made it clear that he wants a championship-caliber coach, and a Super Bowl pedigree will be important for potential candidates to have. Gase and Del Rio have both reached the Super Bowl, but neither of them own rings—Quinn and Kubiak do, and that could set them apart from the competition. Update: Del Rio actually won a ring with the Ravens in 2000.

Austin was on the losing end of Super Bowl XL with Seattle in 2006 and Super Bowl XLIII with Arizona in 2009. He won Super Bowl XLVIII with Baltimore in 2012.

Three coaches not being considered at the moment: Tony Dungy, Mike Shanahan, and Urban Meyer. Meanwhile, Fox will travel to Chicago on Wednesday to interview for the Bears' position, per Klis.

Stay tuned.
