The Cowboys' offseason was plagued by defensive injuries, but this is a healthy squad overall. The only starter on injured reserve is guard La'el Collins, and the Cowboys may have upgraded at the position when Ronald Leary replaced him. Cornerback Morris Claiborne is the only key starter out of action, although he's expected to return from a groin injury before the end of the season. The Cowboys have enjoyed positive injury luck this season and can only hope that continues over the next month. Injuries happen, and the team can't run out the clock on this regular season out of fear.
