Kevin Clancy will be the intermediary when Aberdeen take on Ross County in a Scottish Premiership match this weekend.
The Dons are in ninth place in the table, but only 3 are ahead of Staggies, who are in the relegation play-off spot.
Clancy will be in charge of an Aberdeen game for the sixth time this season, and the Dons have yet to win when he is referee.
He was the referee when the Dons rallied from a 3-0 deficit to draw 3-3 with Motherwell last month.
He took note of the 2-0 defeat to Hearts in January, the 2-0 defeat to Kilmarnock in October, the 2-0 defeat to Hearts at Tynecastle in September and the 3-1 home defeat to Celtic in August.
Clancy has refereed one County Ross match this season: a 1-0 win for the Staggies at Kilmarnock in September.
His assistants at Pittodrie on Saturday will be Chris Rae and Gordon McCabe with George Calder as the fourth official.
Steven Kirkland is in charge of VAR with VAR assistant Graham McNeillie.
