Kurt Warner’s ageless arm and an improbable goal-line stand at the finish saved the Arizona Cardinals from an ugly loss on a national stage.

The Cardinals stopped Michael Robinson up the middle from the 2-yard line as the game ended Monday night to preserve a 29-24 victory over the San Francisco 49ers.

Warner finished 32-of-42 for 328 yards and three touchdowns without an interception in Arizona’s sixth consecutive home victory, fourth this season.

The NFC West-leading Cardinals (6-3) never led until Karlos Dansby’s 34-yard interception return set up Warner’s 5-yard TD pass to Anquan Boldin with 4:16 to play.

San Francisco (2-7) had two chances after that.

The first ended on Adrian Wilson’s diving interception of Shaun Hill’s pass. The second was much more nerve-racking for the home team and exasperating for the 49ers, who lost their sixth in a row.

Hill’s 14-yard pass to Jason Hill moved it to the Arizona 1. With the last few seconds ticking off, 49ers running back Frank Gore was pushed by a defensive player as he ran around left end, then stumbled to the ground just outside the 2.
