BUFFALO, N.Y. — The Buffalo Bills parted ways with defensive lineman Mark Anderson just one year after they signed him to a four-year deal.

Touted as a high-profile signing after a 10-sack performance with New England in 2011, Anderson agreed to a four-year, $21 million contract with Buffalo in 2012.

But he battled injuries for the Bills during his lone season, which led to his release. He made just five appearances, registering 12 tackles and one sack as the Buffalo defense allowed 435 points, most in the AFC East. The Bills finished 6-10 and have since retooled their defense. Anderson wasn’t in the long-term plans.
