Reebok jersey nfl replica????

I bought an game worn jersey Reebok but the tag is different, from american memorabilia, so all jersey made by Reebok, but i don't know Nike élite jersey, are replica , they aren't the same of the player so you bought an "authentic" jersey Reebok also from nfl shop but it isn't the same of the player but it is a replica
The Reebok jersey of the player aren't by retail but only from game worn
