The Tampa Bay Buccaneers getting upset by the Carolina Panthers wasn’t the craziest thing that happened on Sunday. It was something that happened after the game.

NFL referees Jeff Lamberth and Tripp Sutter were seen on video asking for Mike Evans’ autograph after the game. This is against the rules of the current NFL-NFLRA CBA.

The rule is as follows: “game officials shall not ask players, coaches or any other team personnel for autographs or memorabilia.”

NFL Network’s Tom Pelissero reported that the NFL is looking into the incident following the Buccaneers 21-3 loss.

The referees approached Evans while he was heading to the locker room. The video appeared to be shot in one of the tunnels at Bank of America Stadium. Lamberth and Sutter are seen getting something signed by Evans in the video.

The NFL might release a statement about the incident in the coming days. We’ll keep you updated if anything happens with it.
