The Buffalo Bills have lost out on a second free agent they fought hard to sign (the first being Paul Posluszny). ESPN's Adam Schefter reports that Pro Bowl right tackle Tyson Clabo has reached an agreement to re-sign with the Atlanta Falcons.

With the Pittsburgh Steelers re-signing their own right tackle in Willie Colon earlier this evening, the Bills have missed on two tackles that they've been linked to. Clabo is the bigger blow, as they've been in the race for his services for the better part of 48 hours.

It's unclear at this point whether or not the Bills will pursue other options on the offensive line via free agency, but GM Buddy Nix has made it clear that he's happy with the current players on the roster at the position. If tackle goes unaddressed, Erik Pears and Mansfield Wrotto will likely be the top two considerations to start at right tackle.

At this point in time, the only remaining unsigned free agent that the Bills have been linked to is San Diego Chargers inside linebacker Kevin Burnett.
