Real Madrid have officially confirmed that first-choice goalkeeper Thibaut Courtois has been diagnosed with sacroiliitis — an inflammatory condition that affects the sacroiliac joints, typically caused by high physical stress or trauma.

The diagnosis came following a thorough medical examination conducted earlier today by the club’s medical team. While the exact timeline for Courtois’ recovery remains undisclosed, the Belgian international is now a doubt for the upcoming FIFA Club World Cup.

Real Madrid are set to kick off their Club World Cup campaign on June 18 against Al Hilal. If Courtois is ruled out, Ukrainian goalkeeper Andriy Lunin is expected to step in between the posts for Los Blancos — offering him a major platform on the global stage.

Madrid's group-stage schedule also includes clashes with Pachuca on June 22 and Red Bull Salzburg on June 27. With Courtois sidelined, all eyes will be on Lunin to see if he can seize this high-profile opportunity at a critical point in his Real Madrid career.
