Lions' quarterback Daunte Culpepper praised Panthers' defensive end Julius Peppers after he was sacked twice by the defender on Sunday. "When we do our game plans on Wednesday, he's the guy who has 'red alert' on him," said Culpepper, who previously faced Peppers while playing for the Vikings. "We always have to know where he is. "He's a game-changer. He's an absolute beast out there. I love competing against him because he's one of the best." Peppers has nine sacks on the season.
