The NFL plans to talk to Washington Redskins quarterback Robert Griffin III after the rookie covered up a Nike logo on his shirt during pregame warmups Sunday morning in New Orleans, according to a person familiar with the matter.

Griffin, a high-profile Adidas endorser, took the field on Sunday wearing a white, long-sleeved Redskins athletic shirt, on which the Nike “swoosh” logo had been obscured by the word “HEART.” The word appeared to be hand-drawn with a black marker. Nike replaced Reebok this season as the NFL’s exclusive maker of licensed on-field apparel.

“I have not heard from the league yet,” Griffin said with a smile during his weekly news conference Wednesday at Redskins Park. “That’s all I’ll say about that.”

Griffin will not be fined for Sunday’s incident, according to the person familiar with the situation.

The NFL declined to comment through a spokesman. An Adidas spokesman declined to comment. A spokesman for Nike did not respond to a message.

The NFL’s intent to talk to Griffin was first reported by, which quoted an NFL spokesman saying Griffin’s adjustment to the Nike logo “won’t happen again.”

Griffin is already a marketing star, having signed sponsorship deals with Nissan, Subway, Gatorade and several other companies in addition to Adidas.
