New Orleans Saints general manager Mickey Loomis says the club has waived injured defensive end Greg Romeus and signed LB Donavan Robinson.||||||| Romeus, who spent last season on injured reserve rehabilitating a right knee injury, will be eligible for the Saints' injured reserve list again after he clears waivers. Assistant head coach Joe Vitt has said the Saints will support Romeus, a 2011 seventh-round draft pick out of Pittsburgh, throughout his rehabilitation from torn left knee ligaments. The injury occurred during offseason practices this month.
