The Broncos placed DT Kevin Vickerson on injured reserve Monday and claimed FB Quinn Johnson off waivers from the Titans.
Vickerson had four tackles in five games and four starts this season. He played in 15 games with 12 starts last season. He suffered an ankle injury in Sunday's loss to the Chargers.
Johnson played in the Titans' first four games of the season before being waived. He had three catches for 30 yards. He spent last season as a lead blocker for the Packers.
The way we see it
The Broncos are thin on the defensive line, as Marcus Thomas likely will start for Vickerson the rest of the way. DL Ty Warren is also on injured reserve. Johnson should help in the run game.
