Moore underwent emergency surgery to stop bleeding in a muscle in his left leg Monday. By placing him on recallable IR, the Broncos can bring Moore back to practice in six weeks and onto the active roster if they're playing in eight weeks, which would be the week of the AFC title game in January.
Broncos executive vice president of football operations John Elway said, "obviously it hurts to lose Rahim, he'd been playing so well."
Huff was the seventh pick of the 2006 draft by the Raiders. He signed as a free agent with Baltimore last offseason but played sparingly in seven games this year before the Ravens released him.
