Man In The Middle: Andy Davies
Davies, from Lancashire, has been refereeing Football League fixtures since 2012, and has took charge of twenty-two games this season, six of them in the Championship.
This will be the first Watford game that Davies has refereed.
He has issued seventy-six yellow cards in the twenty-two games this season, and dismissed five.
Only one fixture out of the twenty-two Davies hasn't shown a yellow, and only two where he has shown a maximum of one.
Davies' last game to patrol was the Sky Bet League One clash between Colchester United and MK Dons, where he sent three players into the book.
