The Dallas Cowboys do not officially retire numbers. However, no one has worn 74 since Bob Lilly retired and no one has worn 12 since Roger Staubach retired. It is unlikely any future player will wear #8. Correct, the Cowboys do not retire numbers, but no one has warn those numbers in the regular playing season. Numbers worn in pre-season are by rookies are not always their assigned numbers, but those numbers have been worn in summer camp, but not assigned in regular season.
