The newly signed players have their numbers and some other players changed theirs.
The free agent acquisitions the Arizona Cardinals made now have numbers for their uniforms. Since they were signed, if you looked at the roster on the team site, the new players didn't have a number.
They do now.
Here are the numbers for the new free agents:
A.Q. Shipley, C/G: 53 (He has worn five different numbers in his career. 53 is one of them.)
Sean Weatherspoon, ILB: 55 (This was John Abraham's number. Weatherspoon wore 56 in Atlanta.
