Shaky start for Arizona's Warner

Posted by ESPN.com's Mike Sando

GLENDALE, Ariz. -- Kurt Warner isn't doing anything to pad his MVP credentials in the early stages of the Cardinals' game against the Vikings.

Warner threw too high for Steve Breaston on a pass the Vikings intercepted. Vikings linebacker Chad Greenway nearly picked off another pass. That's one interception and one near-interception in two Cardinals possessions.

This game represents an important test for the Cardinals. They're at home against an NFC opponent with a winning record. They'll face similar circumstances -- with higher stakes -- when they open the playoffs.
