BOBBY Madden will be the man in the middle when Celtic host Aberdeen at Parkhead on Saturday in the Scottish Premiership.
The 37-year-old Fifa referee will take charge as the top-two in the last two seasons meet for the first time this season (KO 15:00 BST).
He will be ably assisted by Stuart Stevenson and Gavin Harris, while Steven McLean will be the fourth official.
Madden handled the previous encounter between the champions and the challengers – Celtic’s 3-2 win in May which mathematically sealed their fifth successive title.
He also officiated Celtic’s 2-1 win in September 2014, remembered for Aleksandar Tonev receiving a seven-game ban for racially abusing Dons full-back Shay Logan.
Domestically, Madden was promoted to Category One in 2009 and has built up a wealth of experience and respect to become a Scottish top-flight regular since his first match in January 2011.
He first took up the whistle in 2002 and last year revealed that an advert in the East Kilbride News – spotted by his brother Jamie – inspired him to become involved in refereeing after realising he wouldn’t make the grade as a professional player.
Since joining the Fifa list in 2010, Madden has refereed several Europa League games and been an additional assistant referee for Champions League matches, the 2015 Uefa Super Cup, and part of Willie Collum’s team of Euro 2016 officials for two group games.
The East Kilbride-born whistler has also controlled several domestic cup semi-finals and play-off matches, with his biggest honour coming in 2015 when appointed to referee Celtic’s 2-0 win over Dundee United in the League Cup Final at Hampden Park.
Saturday’s game at Celtic Park – surprisingly not being broadcast live on TV – will be Madden’s seventh of the campaign in all competitions, his third in the top-flight.
He has so far brandished 15 yellow cards, sent off one player and awarded four penalties – three of which came in the space of 23 minutes in St Johnstone’s 3-0 win over Falkirk during the Betfred Cup first round group phase.
Elsewhere, Kevin Clancy will take charge of Rangers’ Friday night trip to face Kilmarnock at Rugby Park and Greg Aitken will oversee his first top-flight game of the season when Hamilton host Ross County on Saturday.
