The EFL have announced the officials who will take charge of Vale's game this weekend.
Richard Clark will be the man in the middle of Port Vale’s Sky Bet League One clash with Charlton Athletic at The Valley.
Clark has officiated in three League One games and two League Two games, giving a total of 16 yellow cards so far this campaign.
It will be the first Port Vale fixture Clark has officiated in this season and his first game since Vale’s 1-1 draw with Peterborough United last season at Vale Park.
He will be assisted by Colin Lymer and Adrian Waters, while Christopher Wade will act as fourth official.
