Courtois suffered an anterior cruciate ligament injury shortly before the start of the season in August, only returning to action against Cadiz earlier this month.

He is seen as the favourite to start between the sticks when Los Blancos face Borussia Dortmund in the Champions League final on Saturday, despite Andriy Lunin impressing as Carlo Ancelotti's side overcame Manchester City and Bayern Munch in the last two rounds.

Courtois became embroiled in a public spat with Belgium coach Domenico Tedesco last June, walking out on the squad when he was not named captain in the wake of Eden Hazard's retirement.

That incident meant he was always unlikely to feature at this year's tournament in Germany, and his absence has now been confirmed with Koen Casteels, Thomas Kaminski and Matz Sels the three shot-stoppers named in Tedesco's 25-man party.

There is, however, a recall for Axel Witsel, who announced his international retirement last May but has now reversed that decision.

Belgium begin their Group E campaign against Slovakia in Frankfurt on 17 June, before taking on Romania five days later and Ukraine on 26 June. 

Full 25-man squad: Koen Casteels (Wolfsburg), Thomas Kaminski (Luton Town), Matz Sels (Nottingham Forest), Timothy Castagne (Fulham), Maxim De Cuyper (Club Brugge), Zeno Debast (Anderlecht), Wout Faes (Leicester City), Thomas Meunier (Trabzonspor), Jan Vertonghen (Anderlecht), Arthur Theate (Stade Rennais), Axel Witsel (Atletico Madrid), Yannick Carrasco (Al Shabab), Kevin De Bruyne (Manchester City), Orel Mangala (Lyon), Amadou Onana (Everton), Youri Tielemans (Aston Villa), Arthur Vermeeren (Atletico Madrid), Aster Vranckx (Wolfsburg), Johan Bakayoko (PSV), Charles De Ketelaere (Atalanta), Jeremy Doku (Manchester City), Romelu Lukaku (Roma), Dodi Lukebakio (Sevilla), Lois Openda (RB Leipzig), Leandro Trossard (Arsenal).
