Man in the middle: Andy Woolmer
Andy Woolmer is the man in the middle for Swansea City's clash with Middlesbrough on Saturday (3pm).
The Northamptonshire official will take charge of the Swans for the first time at the Liberty this season, having previously overseen the win at Brentford and the defeat at Bristol City.
The experienced Woolmer has been officiating in the Football League since 2004, and once refereed at the Vetch Field in a 1-0 win over Leyton Orient.
He will be assisted by Timothy Wood and Dean Treleaven, while Richard Hulme is the fourth official.
