The reigning Super Bowl champion Broncos will be without starting defensive end Vance Walker this season after he tore his ACL in practice Monday.
Walker, a seventh-round draft pick by the Falcons in 2009, recorded 33 tackles and two sacks last season for the Broncos. He was expected to replace Malik Jackson, who signed a huge contract with the Jaguars in March.
