Andre Marriner was once forced to leave an Under nines game due to his language while watching his son play football.
The veteran Premier League referee was reportedly asked to leave pitchside for mouthing off at the official in charge of a children's game, with his regular demeanour with whistle in hand deserting him when on the touchline.
As a referee, Marriner has a reputation for allowing the game to unfold and remain relaxed in key moments.
However, even one of the division's most experienced officials is known to get caught up in the moment on occasion when his child is in action, according the The Guardian.
