The Bills paid a $1 million bonus this season to Merriman already. Merriman has been plagued with injuries since joining the Bills. He was out of practice with a tight hamstring, but had told reporters he was fine.
Merriman considered this year as the best chance to revive his career after season-ending surgery in November to repair a partially torn right Achilles tendon. It's an injury that had nagged him for much of the previous two seasons.
The seventh-year player was entering his third season in Buffalo after the Bills claimed him off waivers after Merriman was cut by San Diego in November 2010.
At his peak, Merriman was regarded as one of the league's top pass-rushers, and earned the nickname "Lights Out."
Merriman has tweeted the following: I want to say Thanks to the Organization, the Coaches, my teammates & the fans you guys have been great & I'll be looking forward to the chapter.
