Currently, no Dallas Cowboys player wears the #33.
I think it unlikely that any one would try to wear 33, as it belonged to Hall of Famer Tony Dorsett. While the Cowboys do not retire numbers, I don't think you will see a 12,8,33, or 74. 88 lingers on, however.
Safety Roy Williams wore No. 31 during the 2006 season.
Safety George Teague wore #31 between 1998-2001. Williams came to the Cowboys in 2002.
