The Broncos on Monday claimed defensive back Antwain Spann off waivers from Buffalo and waived receiver Travis Shelton.
Spann played for New England from 2006 to 2008 and competed in training camp this season with the Buffalo Bills. He entered the league with the New York Giants in 2005 as an undrafted free agent.
Spann has appeared in 19 career regular-season games and totaled 11 special-teams tackles along with one defensive stop. He has also played in three postseason games, notching two special teams tackles.
