The Broncos may be making a veteran addition to their defense.
Barron played 15 games and made nine starts for the Steelers last season. He had 82 tackles, three sacks, an interception and a fumble recovery in those appearances.
Barron, who was a 2012 Buccaneers first-round pick and went on to play for the Rams, would help the team cover for the absence of inside linebacker Todd Davis. Davis is out indefinitely with a calf injury.
