After spending part of Saturday and Sunday morning in Pittsford at training camp with the Buffalo Bills, free agent inside linebacker Nick Barnett will be calling Buffalo home for the next three seasons.

"God has blessed me once again to be part of a great organization.. Great coaches, Great staff, Great players and more importantly great fans," wrote Barnett just moments ago on his Twitter page. He then ended his post with the hashtag "#GOBILLS".

ESPN's Adam Schefter reports that Barnett's deal with the Bills will pay him $12 million - including $6 million guaranteed - over three years. Barnett, 30, was released by the Green Bay Packers just a few days ago. He has missed a combined 19 games over his last three seasons, including 12 during the Packers' Super Bowl championship season a year ago. The 6'2", 236-pound veteran was coached by Bills outside linebackers coach Bob Sanders when the two were together in Green Bay, and has experience in both 4-3 and 3-4 defensive alignments. It's likely that he'll replace the departed Paul Posluszny in the starting lineup.

Also per his Twitter page, Barnett is already impressed with Bills fans. "You bills fans are great here on twitter," Barnett writes. "How bout in the stadium?" Barnett will have that answer soon enough.
