Man in the middle: David Webb
David Webb will be the man in the middle when Swansea City visit Leeds United in the Sky Bet Championship on Wednesday night (7.45pm).
The County Durham official has already taken charge of the Swans this season, having overseen the 2-1 win over Sheffield Wednesday in December.
He last refereed a Swansea away game in the Championship in April 2011, when they lost 2-1 at Burnley.
He will be assisted by Mark Russell and Shaun Hudson, while Robert Jones will be the fourth official.
