Denver Broncos cornerback Champ Bailey and running back Mike Anderson each suffered injuries during Sunday's season- opening loss at Miami. Bailey sustained a sprained left shoulder in the first half, while Anderson left in the first quarter with a rib injury. "Mike Anderson has cartilage in a rib. We won't know how severe it is until he has an MRI. Champ Bailey suffered a shoulder separation. We don't know the degree of the injury yet," Broncos head coach Mike Shanahan said after the 34-10 setback. Bailey intercepted a pass before leaving the contest, while Anderson had just five yards on four carries.
