Man in the middle: Stephen Martin
Stephen Martin will be the man in the middle when Swansea City host Birmingham at the Liberty Stadium on Tuesday night (7.45pm).
The Staffordshire official will be taking charge of a Swansea game for the second time, having last had the whistle for the League Cup win over Rotherham in August 2014.
Martin first refereed in the Championship during the 2013-14 season, and this will be the 14th second-tier fixture he has been at the helm of this term.
He will be assisted by Mark Pottage and Dean Treleaven, while Gavin Ward is the fourth official.
