Redskins quarterback Robert Griffin III has been fined $10,000 by the NFL for his post-game attire after the Redskins' Week 14 win over the Baltimore Ravens, the NFL announced Wednesday night.

Griffin violated the league protocol by wearing an Adidas sweatsuit and t-shirt to the post-game press conference. Though Griffin has a personal endorsement deal with Adidas, the league's official equipment sponsorship belongs to Nike. Griffin left that game in the closing stages of the fourth quarter with a leg injury, while backup Kirk Cousins led the Redskins to a crucial win.
