Jones died at his home, said Tracy Moberly, a friend of the family. Diabetes and cardiovascular disease were listed as the causes of death, according to the Dallas County medical examiner's office.

Known as the Cowboys' unofficial mascot, Jones entertained fans with sideline antics and magic tricks while wearing his signature chaps, six-shooter and blue vest.

Though he was not paid by the Cowboys, he was given a special parking space at Texas Stadium and granted all-access at home games.

''He touched thousands of lives and generations of football fans,'' Cowboys owner Jerry Jones said on the team's Web site. ''He will remain an important part of this team's heritage and family for as long as fans go to Cowboys games and feel his spirit.''
