[HELP] My Career "nickname" REMOVAL

Is it possible to remove the nickname of my player in my career? My player nickname is "Dub" and sometimes the announcer says my last name which is McCray. Is it possible to remove my nickname so that the announcer will stick on may last name and also if he can pronounce my first name which is Nicolo it will be so much better. If you ever knew how to edit please tell me step by step. THANK YOU!!!!

McCray Is Probably Not in The System.

McCray is definitely in their system. Try it your self change your may player name to McCray.
