Mike Jones of The Washington Post got this tidbit straight from the horse's mouth.
Montgomery, who took over as starting center last season, was set to become a free agent, but has agreed to a four-year deal and won’t hit the open market on March 13.
Montgomery was one of two offensive linemen to play all 16 games in 2011 (Chris Chester was the other; now there's one for trivia night) and spent time at both center and left guard, where he moved after Kory Lichtensteiger went down with a knee injury.
Montgomery would have officially been a free agent on March 13, and given how many quarterbacks the Redskins have been linked to this offseason, both via free agency and by the draft, we deem it highly relevant that Washington makes sure their offensive line is as secure as possible entering training camp.
