Lee Mason will take charge of Swansea City’s Premier League home fixture against Watford on Saturday (3pm).
Mason, from Lancashire, has previously refereed eight times at the Liberty.
The 45-year-old was also the man in the middle for the Swans’ most recent meeting with the Hornets, who prevailed 1-0 winners at Vicarage Road in April, while he also oversaw the 1-1 draw in March 2011.
Mason has refereed 227 matches in the top-flight, issuing 694 bookings and 37 red cards.
He will be assisted on Saturday by Harry Lennard and Matthew Wilkes, while James Linnington is the fourth official.
