The Buffalo Bills have agreed to a four-year contract extension with converted linebacker Chris Kelsay. "We signed an extension (Tuesday) and got everything finalized, a four-year extension," said Kelsay. "I'm very pleased. I think both sides are very happy with the situation and it gives me an opportunity to finish my career a Buffalo Bill." Kelsay was a second-round pick of the Bills in 2003 and has appeared in 113 games for Buffalo making 90 starts. He made no secret that it was a priority for him to spend his entire career with one NFL franchise. Source: Chris Brown, BuffaloBills.com
