Chad Johnson of Cincinnati, Larry Johnson of Kansas City and Jay Cutler of Denver were among star players who were hurt Sunday.
Chad Johnson's injury was potentially the most severe, but he flew home with his teammates after medical tests showed he sustained no damage to his neck after being hit late in Cincinnati's 33-21 loss to Buffalo.
Johnson joined the team for its scheduled flight to Cincinnati after having a CT scan of his neck at a Buffalo-area hospital. Test results were normal.
Larry Johnson was helped off the field at Arrowhead Stadium after injuring his right ankle midway through the fourth quarter against the Packers. He caught a pass from Damon Huard and was dragged down from behind by linebacker A.J. Hawk, catching his toe in the turf.
