The Bills have re-signed linebacker Shawne Merriman to a two-year deal. Buffalo general manager Buddy Nix confirmed the deal on Saturday. Merriman has been riddled by injuries and did not play a down for the Bills after he was claimed off waivers at midseason. "We know the situation, we researched it, we did all our homework with Shawne," Nix said. "Everything you do is a little bit of a gamble. There's reward and upside to it and I think both sides are happy with the way the contract is structured."
