It's believed Gordon, a running back from Wisconsin, has an ankle injury.
''We're going to give some guys some rest as time goes along. Some guys have little bumps and bruises as camp goes along,'' said McCoy, who loathes discussing injuries. ''We're taking care of guys as we go and they're going to grind it out when it's their time to go. Some days we'll say, `You've got to rest a little bit' to get them healthy, or just to get their legs fresh, whatever that is. A number of different reasons.''
McCoy declined to say whether Gordon will play Saturday night at Arizona.
