Chiefs quarterback Brodie Croyle will miss the remainder of the season with a sprained right knee. Croyle returned from a separated shoulder on Sunday against the Titans, but just fourteen plays into the game, he was knocked out with ligament damage in his knee. "He's been hurt, there's no doubt about that," Chiefs coach Herm Edwards said. "This is the worst one he's had. This is a tough one here. This is the rest of the year, so it's tough on everybody; tough for him, tough for this football team."
