ILB Paul Posluszny agreed to terms on a six-year deal with the Jaguars, according to NFL Network's Jason La Canfora.
Posluszny was an unrestricted free agent. The deal won't be made official until Friday afternoon. In 14 starts last season, Posluszny recorded 151 tackles and two sacks.
The Jaguars play a 4-3 defense, while the Bills will be using some 3-4 and 4-3.
"I have so much respect for the Buffalo organization," Posluszny's agent, Mike McCartney, told the Buffalo News. "They did everything they could to keep him. ... But he felt more comfortable in a 4-3 defense. He felt he came into the league playing the 'Mike' in the 4-3. I want to emphasize how much respect I have for Jim Overdorf and the Bills. It was a tough decision."
The way we see it
He's not much of a playmaker in terms of sacks or forced fumbles, but he was a tackle machine and a locker-room favorite. The Bills drafted Kelvin Sheppard, who may be thrust into the lineup earlier than expected. Posluszny could be replacing Kirk Morrison, whose future is uncertain.
