Williams had two years left on a contract extension he signed last offseason. He played at right tackle and right guard, starting all 17 games last season and 33 overall in two years with Buffalo.

Cutting the seventh-year player leaves Buffalo about $6.2 million under the cap and leads to the expectation that more salary-related moves are coming before free agency opens on Wednesday.
