According to the Associated Press, "The Bengals placed linebacker Lemar Marshall on injured reserve Tuesday, a day after he tore the Achilles' tendon in his left leg during a 34-13 loss to New England... The Bengals replaced him by claiming linebacker Corey Mays off waivers from New England." Tough blow for the Bengals, no doubt about it. That defense can't afford to get much worse.
