Meet the officials | Sheffield United
David Webb will be the referee when Swansea City take on Sheffield United at Bramall Lane on Saturday (3pm).
The County Durham official will be taking charge of a Swans game for the fourth time this season, having had the whistle for the opening-day defeat at Blackburn, the away win at Barnsley and the draw at Huddersfield.
Webb was at the helm of two Swans games last season, awarding a key spot-kick for Andre Ayew to net a late winner at Stoke, and overseeing a goalless draw against Reading.
He will be assisted by Adam Crysell and Geoffrey Liddle, while Jeremy Simpson will be the fourth official.
