Presumably the gentleman who was on the line at Rutherglen Glencairn many years ago, but has been a Scottish FA Specialist Assistant since 2015.
Wonder what he's doing in the EFL?
He has done three matches in the National League Premier this season, Hartlepool V Altrincham, Chesterfield V Maidenhead and Notts County V Boreham Wood. He has not officiated in the SPL since the end of the 2018/19 season.
