Report: John Fox on Broncos' short list

The Denver Broncos reportedly want to interview John Fox as they look to fill their head-coaching vacancy.

And they are in the process of getting permission from the Carolina Panthers to do so, according to The Denver Post -- despite the fact he's officially been ruled out to return for another season with the team.

Fox, whose Panthers finished an NFL-worst 2-14 in 2010 in the last season of his deal with the team, is technically still under contract with Carolina for a few weeks, according to The Post, which cited an anonymous NFL source in its report.

Fox is one of a number of candidates for the Broncos as they look to replace Josh McDaniels, fired amid his second season in Denver before the team finished a franchise-worst 4-12.

On Sunday they will interview New York Giants defensive coordinator Perry Fewell, an interim coach for Buffalo in 2009, and Eric Studesville, who went 1-3 as interim Broncos coach after his promotion from running backs coach following McDaniels' firing last month.

Newly hired Broncos boss John Elway tweeted Friday he had received permission to talk with Jaguars offensive coordinator Dirk Koetter.

Elway also said he's seeking permission from the Houston Texans to interview offensive coordinator Rick Dennison, a longtime Broncos assistant who has never been an NFL head coach, and is considering calling former Giants coach Jim Fassel, who tutored Elway in college and in the pros.

General manager Brian Xanders said on Sirius/XM Radio on Friday that San Diego Chargers defensive coordinator Ron Rivera and New Orleans Saints defensive coordinator Gregg Williams are also among those the Broncos are targeting.
