ENGLEWOOD, Colo. --  The 
Denver Broncos are no longer aggressively pursuing Stanford coach 
Jim Harbaugh for their vacant head coaching position.
John Elway,  the Broncos' new football czar, said on his weekly radio show on 87.7  The Ticket in Denver on Friday that he believes Harbaugh wants to stay  at Stanford, where star quarterback 
Andrew Luck will return next season rather than turn pro.
Elway  said he believes Harbaugh's alma mater, Michigan -- which earlier this  week fired Rich Rodriguez as coach -- might be back in the picture after  Harbaugh listened to pitches from the San Francisco 49ers and Miami Dolphins this week.
Elway said he's seeking permission from the 
Houston Texans  to interview offensive coordinator Rick Dennison, a longtime Broncos  assistant, and is considering calling former Giants coach Jim Fassel.
On Thursday, 
Atlanta Falcons  offensive coordinator Mike Mularkey canceled his interview with the  Broncos, which had been set for Friday night. ESPN NFL Insider Adam  Schefter reported that according to a team source, Mularkey wanted to  focus on the Falcons' playoff run, but would be interested in Denver if  the job remained open after the Falcons' season was over.
       "I respect the decision that Mike Mularkey has made to not  interview with the Broncos at this time," Elway said via his official  Twitter account Thursday. "I wish Coach Mularkey and the Atlanta Falcons  the best of luck in the playoffs."
      With Mularkey scrubbing  his interview, the Broncos' search committee that includes general  manager Brian Xanders, team president Joe Ellis and owner Pat Bowlen,  will remain in Denver preparing to interview 
New York Giants  defensive coordinator Perry Fewell and interim Denver coach Eric  Studesville, both on Sunday, in addition to possibly interviewing  Dennison and Fassel.
      Elway said Thursday he wanted to hire a  coach who already had head coaching experience, preferably in the NFL,  and both Fewell, 48, and Studesville, 43, have been interim head  coaches, Fewell for seven games in Buffalo in 2009.
      "I don't believe anybody that's not had that NFL experience can make that jump -- other than Harbaugh. There's nobody [else] in the college ranks that we're interested in talking to," Elway said. "And preferably we'd like to have some head coaching background in the NFL, but it's not a must. If there's a guy who's a coordinator that's up and coming and shows that he can be the head coach and understands that, then he'll be the guy."
