Kurt Warner and Matt Leinart continued to share snaps with the starting unit on Friday, but Whisenhunt remains optimistic that Warner will start Sunday against the Vikings.
Whisenhunt, however, isn't counting on it as much as last week, when Warner ended up sitting out against the Titans. Leinart didn't take many snaps with the first unit last week, yet played the whole game.
Warner is listed as questionable.
Running back Tim Hightower (thumb), cornerback Bryant McFadden (knee), defensive end Kenny Iwebema (thumb), kicker Neil Rackers (groin) and linebacker Karlos Dansby (shoulders) are questionable. All are expected to play, however.
