A uniform inspector from the NFL reportedly told Redskins quarterback Robert Griffin III that he could not wear his "Know Jesus, Know Peace" T-shirt during a Sunday post-game press conference.

Michael Phillips, a reporter from The Richmond Times-Dispatch, posted on Twitter that an NFL uniform inspector made the quarterback, known as RG3, turn the shirt inside out before the press conference. The reason: it was not a Nike product, Phillips reported.

CSN Washington reported that a Redskins spokesperson denied reports that RG3 was forced to flip the shirt by the NFL. The spokesperson said RG3 flipped the shirt on his own to avoid a possible fine. CSN cites NFL bylaws that state a player cannot wear clothing that sends a personal message on game days. Griffin has reportedly been fined in the past for wearing Adidas gear on game days.

Other players, however, were seen at the podium not wearing a Nike shirt, including Redskins linebacker Ryan Kerrigan. Nike reportedly has a corporate deal with the NFL.
