The NFL fined Robert Griffin III, the Washington Redskins star quarterback, $10,000 for wearing Adidas apparel to a postgame news conference following a win over the Baltimore Ravens on Dec. 9.
The fine was confirmed by an NFL spokesman to csnwashington.com.
Nike is the leagues official uniform maker. Griffin, the number two pick in the recent draft, signed a sponsorship deal with Adidas prior to the season.
League officials said they would issue a warning but not a fine to Griffin earlier this season when he covered the Nike logo on his shirt before a game.
