Key Belgium striker Romelu Lukaku trained for the first time in Brazil on Wednesday after suffering an injury scare and came through unscathed in a timely boost for their World Cup hopes.
Lukaku, who spent a productive campaign on loan at Everton from Chelsea last season, picked up an ankle injury in a physical friendly against Tunisia on Saturday.
"I have my 23 players available and we are delighted to be in Brazil after three weeks of preparation," said Belgium coach Marc Wilmots, who earlier signed a new deal to remain as coach until 2018.
Belgium are in Group H at the World Cup and start their campaign against Algeria on June 17 at Belo Horizonte before facing Russia and South Korea.
An agreement between Wilmots, who has been in charge since 2012, and the Belgian federation had been reached in April but he was waiting for his backroom staff to sign before he committed himself to an updated contract.
