The Broncos on Monday placed defensive tackle Kevin Vickerson on injured reserve.
The team was awarded fullback Quinn Johnson off waivers from Tennessee as a corresponding roster move. In addition, the club waived running back Brandon Minor from injured reserve.
Johnson, acquired by the Titans via trade in September, spent his first two NFL seasons with the Green Bay Packers, serving primarily as a lead blocker. He appeared in 11 games with four starts last season, catching three passes for 26 yards during the regular season, adding five special-teams tackles as the Packers eventually won Super Bowl XLV.
