Because of NFL rules, even in the preseason, two players on the same team cannot have the same uniform number. That makes perfect sense. As such, the Arizona Cardinals had to shift around some jerseys and one of the numbers is a familiar one.
Undrafted rookie linebacker Edwin Jackson, known as Poundcake, is now No. 58, as he was previously No. 45. Moving to No. 45 is safety Brandon Person, who had been sharing No. 34 with running back Paul Lasike.
Another shift was undrafted linebacker Gabe Martin saw his number shift from 41 to 50.
