The Broncos, who were hit with multiple injuries at center in the lead-up to the 2013 season, have added to their options at the position.
The 31-year-old Montgomery has appeared in 90 NFL games, making 63 starts. He has had stints with the Panthers (2006), Jets (2007-2008) and Redskins (2008-2013).
If Montgomery is to start at center, it will necessitate a move of incumbent Manny Ramirez to another position. The Broncos have a vacancy at left guard after Zane Beadles departed in free agency for Jacksonville. Ramirez was the Broncos’ starting right guard for for much of the 2012 season, but the Broncos now have Louis Vasquez in that spot.
