Lenon is a 12-year veteran who played for four teams. The 35-year-old has 809 tackles, 12 sacks, 10 forced fumbles and five interceptions in his NFL career. He most recently spent time with the Arizona Cardinals, starting 48 games in the past three seasons. He recorded 103 tackles, two sacks and one interception in the 2012 season.
The Broncos are thin at linebacker after losing Stewart Bradley to a wrist injury. Bradley had surgery on the wrist and is considered out indefinitely. They are also looking at a possible lengthy suspension for star Von Miller, who could be out for anywhere from six to eight games. Right now the plan is to move Wesley Woodyard from the weakside to the middle while Danny Trevathan shifts over from the nickel spot.
