He's the fourth coach to interview for the job on Mike Singletary's staff that came open when Mike Martz was fired last month. Former St. Louis coach Scott Linehan, Indianapolis receivers coach Clyde Christensen and Cleveland offensive coordinator Rob Chudzinski already have interviewed with Singletary.
Dennison was an assistant to former Broncos coach Mike Shanahan for 14 years, also coaching the offensive line. He won't be retained on new Denver coach Josh McDaniels' staff, but his interview with San Francisco was set up before Shanahan was fired.
The 49ers added two assistant coaches to their defensive staff late Monday, hiring Vantz Singletary as inside linebackers coach and Al Harris as a pass-rush specialist coach.
Vantz Singletary is Mike Singletary's nephew, but he's also a veteran college assistant coach who spent last season as the University of Buffalo's defensive tackles coach.
