Joseph (stinger) was officially placed on the injured reserve list Saturday, Darren Urban of the Cardinals' official site reports.
Joseph suffered a stinger during last week's game against the Rams and has found himself on the injured reserve. The veteran cornerback had been dispatched as the starter in recent weeks, though he's still a valuable depth player. Patrick Peterson, Dre Kirkpatrick and Byron Murphy will serve the starting cornerback roles as Joseph remains out.
