Chelsea goalkeeper Thibaut Courtois has withdrawn from the Belgium squad to face Saudi Arabia due to an ongoing hamstring complaint.
Blues boss Antonio Conte confirmed that the 25-year-old was suffering from a "muscular problem" ahead of last weekend's FA Cup quarter-final win over Leicester City.
Although Courtois joined up with Roberto Martinez's side in hope of recovering in time, Belgium have now announced that the player will play no part in Tuesday's friendly.
"Thibaut Courtois has not recovered from his hamstring injury and left the group," read a statement issued on the team's official Twitter page.
"Roberto Martinez will decide later on who will replace him in goal versus Saudi Arabia. Get well soon, Thibaut."
Liverpool's Simon Mignolet is favourite to start in Courtois's absence, with uncapped duo Koen Casteels and Matz Sels the other goalkeepers in the Red Devils squad.
