With cuts happening across the league the Bills saw an opportunity to improve the depth on the interior of their offensive line. Buffalo was awarded the waiver claim of C Patrick Lewis, who was released by the Seattle Seahawks.
Lewis, 25, has been with the Seahawks the past two seasons appearing in 16 games with 13 starts. In 2014 he started in place of then Seahawks starting center Max Unger, who was injured at the start of that season. After making four starts in 2014, Lewis also started nine times last season for Seattle.
Originally signed as an undrafted rookie with the Green Bay Packers in 2013, Lewis also served time on practice squads with Cleveland and Jacksonville.
To make room on the roster the Bills released undrafted rookie OL Jamison Lalk.
Lewis is not expected to play in Thursday night's preseason finale against Detroit.
