Man in the middle: Geoff Eltringham
Geoff Eltringham will be the man in the middle when Swansea City face Blackburn Rovers at the Liberty on Tuesday (7.45pm).
The County Durham official has never previously taken charge of a Swans match.
Eltringham has been refereeing in the Football League since 2009, and he has been a regular in the Championship in recent seasons.
He has refereed Blackburn once this season, having taken charge of their 4-1 Carabao Cup win over Lincoln.
Eltringham will be assisted on Tuesday by Daniel Leach and Adam Matthews, while Lee Swabey will be the fourth official.
