Cards' Warner returns in 2nd half

NEW ORLEANS -- Kurt Warner returned in the second half of Arizona's divisional playoff game against New Orleans after leaving in the second quarter due to a hard hit on an interception return.

Warner's return was questionable with a chest injury after he was intercepted by Will Smith, then hit by defensive end Bobby McCray. Warner was pursuing Smith when McCray knocked him down.

The 38-year-old quarterback stayed on the ground for a while before walking off under his own power. Backup Matt Leinart came in for the next drive, after the Saints had scored a touchdown to take a 35-14 lead.

Warner missed a game with a concussion earlier this season, and there's been widespread speculation he is about to retire.
