The Pittsburgh Steelers have ruled out wide receiver Antonio Brown, tackle Marcus Gilbert, safety Troy Polamalu and linebacker Stevenson Sylvester for Monday night's game against the Kansas City Chiefs. Brown hurt his left ankle during the first quarter of last Sunday's 24-20 victory over the New York Giants. He leads Pittsburgh with 42 catches this season and has totaled 499 receiving yards with one touchdown through the first eight games. Running back Rashard Mendenhall (Achilles) is doubtful, while linebacker Chris Carter (abdomen) is questionable. Mendenhall will likely miss his fourth straight contest. Source: Sports Network
