ST. LOUIS (AP) Kurt Warner spent the second half pacing the sideline after taking a blow to the head, still in uniform but shut down for the day. The Arizona Cardinals quarterback had already done enough to make it three straight victories over his former team in the stadium where he rose to stardom.

Warner threw for 203 yards and two touchdowns while building a 21-3 cushion, and the NFC West leaders hung on late, remaining unbeaten on the road with a 21-13 victory over the St. Louis Rams on Sunday. Tim Hightower had 110 yards on 14 carries, the first 100-yard game of the season for a team ranked next to last in the NFL in rushing, helping the Cardinals (7-3) win for the sixth time in seven games.

Steven Jackson became the first Rams player to post five consecutive 1,000-yard seasons, gaining 116 yards on 24 carries with a fourth quarter touchdown that cut the deficit to eight points. It's also the fourth straight 100-yard game for Jackson. (MORE)
