Man in the Middle: Jon Moss
Jon Moss will take charge of Swansea City’s Premier League fixture against Chelsea at the Liberty Stadium on Saturday (5.30pm).
West Yorkshire official Moss will be the man in the middle for a Swans game for the third time this season.
Moss took charge of the 4-0 loss to Manchester United in the Swans' opening home game of 2017-18, while he was also in control when Paul Clement's team were beaten 3-1 at Everton in December.
Moss, who joined the select group of officials in 2011, last refereed a Swans victory when Leicester City were beaten 2-0 at the Liberty in March last year.
He will be assisted on Saturday by Adrian Holmes and Harry Lennard, while Chris Kavanagh is the fourth official.
