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.
No. 31 is worn by cornerback Mario Butler, a member of the Dallas Cowboys' 2011 practice squad.
No one on the 2011 Dallas Cowboys rosters wears No. 71.

Safety Roy Williams wore No. 31 during the 2006 season.
