‘Oliver was injured in the second quarter of Buffalo’s 40-9 victory at Carolina on Sunday. It was Oliver’s second game back after missing four weeks with an ankle injury sustained in practice, and it left the Bills without both starting defensive tackles following DaQuan Jones’ calf injury during pregame warmups two weeks ago at Atlanta. Further thinning the line, rookie T.J. Sanders is on injured reserve following knee surgery earlier this month, and second-year player Dewayne Carter was lost for the season with an Achilles tendon tear before the start.’
