The Buffalo Bills have been busy as the hours before free agency melt away.
An NFL source informs me they are on the verge of re-signing versatile offensive lineman Kirk Chambers, who started at three positions last year.
The NFL Network's Adam Schefter reports the Bills also have released tight end Robert Royal. A disappointing free-agency acquisition three years ago, Royal had 33 catches for 351 yards and one touchdown last year. He also lost a pair of fumbles.
Chambers would have been an unrestricted free agent.
The fifth-year pro played in all 16 games, mostly as a backup. But he started the season opener at right tackle, started at right guard in Week 10 and started the last two games at left tackle for injured Pro Bowler Jason Peters.
