Marc Wilmots has been forced to make an alteration to his Belgium squad for this summer's World Cup.

It had been hoped that third-choice goalkeeper Koen Casteels would be fit in time for the tournament following a leg injury that he suffered in April.

However, the Hoffenheim stopper has not recovered, which has prompted Wilmots to select Sammy Bossut, who keeps goal for Zulte Waregem, in his place.

Casteels had only originally been included in the squad because Anderlecht's Silvio Proto had suffered a broken arm.
