Broncos put Miller on IR, sign Marshall
Marshall is a second-year player who played in five games as a rookie for Jacksonville after being drafted in the fifth round out of Nevada.
The Broncos decided to promote Marshall, who spent the season on their practice squad, rather than bring in a free agent who hadn't been with the team.
Miller was placed on IR after tearing his right anterior cruciate ligament Sunday in Denver's 37-13 win at Houston.
That ended a rough season that began with a six-game drug suspension and included just five sacks in 10 games for the 2011 NFL Defensive Rookie of the Year.
