Chad Ocho Cinco took the field in Baltimore for warm-ups Sunday with his new last name across the top of the back of the jersey. When he re-appeared for the start of the game, his jersey read C. Johnson again. ALhough last week when the NFL and the Bengals officially recognized Johnson's legal name change to Chad Ocho Cinco, Reebok doesn't. "He has a financial obligation to Reebok, which produces the jerseys available to fans," NFL spokesman Greg Aiello told the Associated Press Sunday. "That has to be resolved before the on-field jersey can be changed. The same obligation exists for any player that changes his number or name."
