The NFL has fined Redskins quarterback Robert Griffin III $10,000 for wearing an "Operation Patience" shirt, according to the Washington Post.
Griffin violated the NFL's apparel rules during pregame warmups prior to the Redskins' Monday preseason game against the Steelers, according to the Post.
From the Post:
Griffin did not play in the game Monday night. The Redskins plan to withhold him from the entire four-game preseason as he works his way back from knee surgery in January. He did drills on the field before the game Monday night wearing a shirt that said, “Operation Patience,” which he said early in training camp he was calling the team’s plan to ease him back toward full-time duties.
"Operation Patience" shirts sport an Adidas logo on the back which competes with the NFL's official apparel deal with Nike.
