Man in the middle: Scott Duncan
Scott Duncan will be the man in the middle when Swansea City face West Brom at The Hawthorns on Wednesday (8pm).
The Northumberland official has been refereeing in the EFL since 2012, and will take charge of a Swans game for the second time this season.
Duncan had been at the helm for the goalless draw against Nottingham Forest in September.
He will be assisted by Steven Meredith and Adam Matthews, while Lee Swabey is the fourth official.
