SCOTTISH referee Willie Collum will take charge of his second Euro 2016 match when the Czech Republic face Turkey in Lens on Tuesday night.
The 37-year-old will be in the middle at the Stade Bollaert-Delelis as both sides play their final Group D games, with the Czechs needing to win to have any chance of reaching the last 16 (KO 20:00 BST, live on ITV4).
He will be ably assisted by Francis Connor and Irish linesman Damien MacGraith, with Bobby Madden and John Beaton acting as additional assistants.
Russia’s Sergei Lapochkin will be the fourth official, while compatriot Nikolai Golubev is the reserve assistant.
Collum – a Religious Education teacher from Belshill, north Lanarkshire – is taking part in his first major international tournament as a referee.
The Glasgow-born whistler went to the Under-20s World Cup in Colombia in 2011 and was an additional assistant referee in Craig Thomson’s team of officials at Euro 2012.
Father-of-three Collum, who has been on the Fifa list since 2006, described being selected as one of 18 referees for Euro 2016 as ‘the proudest moment of his career without doubt’.
With Scotland having failed to qualify for the tournament, the Uefa Elite Category official could stay beyond the group phase without the intervention of his nation’s progress.
Collum – who dished out nine yellow cards in Barcelona’s 5-4 win over Sevilla in last year’s Uefa Super Cup – encountered the Czechs in their 2-1 defeat to Iceland in qualifying but has never previously officiated a Turkey international.
The host nation’s sole refereeing representative Clement Turpin will be at the helm for Northern Ireland’s encounter with Germany on Tuesday.
The 34-year-old French official, who is the youngest of the 18 referees at the tournament, will take charge as both sides seek to book their place in the last 16 in their final Group C game (KO 17:00 BST, live on BBC One).
He will be assisted at the Parc des Princes in Paris by Frederic Cano and Nicolas Danos, with Benoit Bastien and Fredy Fautrel as additional assistant referees.
Slavko Vincic is the fourth official, with fellow Slovenian Robert Vukan on standby as the reserve assistant.
Turpin – a referee manager from Montceau-les-Mines – has only been a Uefa Elite Category official for a year, handling six Champions League games and 10 in the Europa League.
He was largely inconsistent in his first match at the tournament and sent off Austria’s Alexander Dragovic for two bookable offences in their 2-0 defeat by Hungary in Bordeaux on Tuesday.
It will be his first Northern Ireland game but Turpin gave out four yellow cards in Germany’s 2-0 win over Georgia in March 2015 during qualifying.
Northern Ireland opened their first ever Euros campaign with a 1-0 loss to Poland before sealing a historic 2-0 success over Ukraine, who Germany also beat 2-0 before the world champions drew 0-0 with Poland.
Norway’s Svein Oddvar Moen will be in the middle for rivals Poland and Ukraine’s final Group C game in Marseille (KO 17:00, live on BBC Four).
The 37-year-old has not been in action since the tournament’s second day when he had a steady game in Wales’ 2-1 win over Slovakia in Bordeaux on June 11 – during which he booked five Slovakia players.
And now he will handle a second match in his first major international tournament as referee, with Poland requiring a positive result to seal a top-two finish against the eliminated Ukrainians.
Moen – an ambulance driver by occupation – was the fourth official for last month’s Europa League Final between Liverpool and Sevilla in Basel.
He hasn’t officiated a Poland game before but was in charge of Ukraine’s 2-1 friendly win over Austria in November 2011, in which he dished out seven yellows and a red card.
Moen has been refereeing since 1995 and has slowly worked his way through the ranks to become an established name on the European stage.
He will be assisted by Kim Thomas Haglund and Frank Andas, with Ken Henry Johnsen and Svein Erik Edvartsen acting as additional assistants.
Turkey’s Huseyin Gocek will be the fourth official, while Bahattin Duran will be on standby as the reserve assistant.
Poland and Ukraine were joint-hosts of the last European Championship finals four years ago.
Tuesday’s other Group D encounter between Croatia and holders Spain in Bordeaux will be officiated by the experienced Dutch referee Bjorn Kuipers.
The 43-year-old has been appointed to keep the peace at the Stade de Bordeaux as the Croats require a point against the 2008 and 2012 winners to seal second spot (KO 20:00 BST, live on ITV).
He will be assisted by fellow countrymen Sander van Roekel and Erwin Zeinstra, and additional assistants Pol van Boekel and Richard Liesveld.
Hungary’s Viktor Kassai will be the fourth official, with compatriot Gyorgy Ring acting as the reserve assistant.
Kuipers has officiated several major finals including the 2011 Uefa Super Cup, 2013 Europa League Final, 2013 Confederations Cup Final and the 2014 Champions League Final.
Among the contenders to take charge of the July 10 showpiece, he is taking part in his third major international tournament as a referee.
Kuipers – a supermarket owner from Oldenzaal – was the fourth official for the tournament opener on June 10 before booking six players during Germany’s goalless draw with Poland in Paris on Thursday.
Spain began with a 1-0 victory over Czech Republic before beating Turkey 3-0 in the biggest win of the tournament so far, while Croatia edged the Turks 1-0 before blowing a two-goal lead to draw 2-2 with the Czechs.
Vicente del Bosque’s Spanish side needed a late Jesus Navas goal to beat Croatia 1-0 in their last meeting at Euro 2012 – a game refereed by Germany’s Wolfgang Stark.
