Cardinals fans held their breaths Sunday as their leader on offense – Kurt Warner, sat on the sidelines with concussion-related symptoms. The QB had done his job, throwing for two scores and 203 yards as he helped the Cards to their third straight win, a 21-13 victory on the road in St.Louis.

“I felt pretty good coming out right after halftime, but I just wanted to be smart,” Warner said. “It was one of those situations where I didn’t feel perfect.”

Arizona was able to get it done on the ground, as they had a season-high 183 yards rushing, including 110 on 14 carries by Tim Hightower for the Cardinals’ first 100-yard game of the season. The Cardinals (7-3) have won six of seven.

It wasn’t all easy though, as the Rams drove to the 7 late in the game needing a TD and a 2-point conversion to tie. Marc Bulger threw incomplete for Donnie Avery in the end zone on fourth-and-4 after some jostling from Arizona’s Dominique Rodgers-Cromartie.

“We were hitting on all cylinders. We were making some big plays, and I think we had them off-balance a little bit,” Warner said. “When we’re clicking and in rhythm, that’s how we can play.”

Warner ended the day 15-for-19, and seemed to have plenty of time to throw until he was hurt. It appeared Warner was hurt by safety O.J. Atogwe’s high hit on a blitz that drove the quarterback’s head into the turf. Warner lay on the field for a few seconds before getting up and stayed in the game for the last six plays of a 90-yard drive capped by Beanie Wells’ 1-yard run.

At that point, he was pulled. “What you don’t want to do,” coach Ken Whisenhunt added, “is jeopardize games down the road.”

The Cards have a tough test next week, a road game at Tennessee, going up against a team that suddenly has turned their season around.
