Koen Casteels has been dropped from Belgium's World Cup squad after the third-choice goalkeeper failed to recover from a broken bone in his leg.
Coach Marc Wilmots had waited until the last possible moment to submit his final 23-man group to head to Brazil as he waited on Hoffenheim stopper Casteels, but has now confirmed Sammy Bossut of Zulte-Waregem will go in his place.
Wilmots originally submitted a 24-man group with the names of both goalkeepers - who sit behind Thibaut Courtois and Simon Mignolet in the pecking order - but confirmed on Tuesday that only Bossut would travel.
"The 23-man list was submitted to FIFA yesterday evening (Monday) before midnight and included the name of Koen Casteels," said a statement on the Federation's website.
"However, a test undertaken by Casteels today showed that the goalkeeper has not sufficiently recovered in time to take part in the World Cup."
Casteels suffered a fractured tibia in a Bundesliga match on 6 April.
Bossut has only one cap to his name, earned last week against Luxuembourg.
