Cardinals shrug off preseason offensive troubles

Posted: Updated:

TEMPE, Ariz. (AP) -- The Arizona Cardinals offense, so brilliant in the team's run to the Super Bowl, has been unproductive in the first two preseason games.

The only touchdown Arizona has scored came late in game one at Pittsburgh, with fourth-stringer Tyler Palko at quarterback.

The Cardinals say, not to worry -- it's just preseason.

Quarterback Kurt Warner says only a few wrinkles need to be ironed out and the offense will be its high-scoring self once the regular season begins.
