Dez Bryant is number 88 on the Dallas Cowboys.
He is currently wearing jersey number 88 with the Dallas Cowboys.
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.
Drew Pearson, Michael Irvin and now Dez Bryant
The most famous was Dallas Cowboys wide receiver Michael Irvin.
Quarterback-punter Danny White wore No. 11 during his career with the Dallas Coiwboys (1976-88).
I don't know who is wearing it now, if anyone, but Michael Irvin wore it back in the Troy Aikman era. The Cowboys don't officially retire jersey numbers like many other teams do, but you're not going to see current players wearing numbers like #12 (Roger Staubach) or #74 (Bob Lilly), and probably not #88 either. Edit: Dez Bryant (OK State) now wears the #88 jersey for the Dallas Cowboys.
Antonio Bryant, a wide receiver from Pittsburgh, wore No. 88 for the Dallas Cowboys from 2002 to 2003. He was drafted by the Cowboys in the second round of the 2002 NFL Draft.
Currently, wide receiver Emmanuel Sanders wears #88 for the Steelers.
Many players but most notably Drew Pearson and Michael Irvin. Now of course it is Dez Bryant.
