During the pregame warmup before Monday night's preseason game against the Steelers, Robert Griffin III sported a t-shirt that said "Operation Patience." The t-shirt referred to the Redskins slowly bringing RGIII back to game action following his ACL injury. 

The NFL is very particular about what players wear during practices, warm-ups and games. They said that his t-shirt did not follow uniform policies (it was not from NFL apparel sponsor Nike) and hit RGIII with a $10,000 fine for an apparel violation.
