Manchester City captain Vincent Kompany is available for Belgium.
Belgium meet Japan in the World Cup round of 16.
Belgium coach Roberto Martinez said: “Romelu Lukaku is fine, he’s fully fit. He completed the training session today [Friday] so he’s got no problems. He should be available.
“Thomas Vermaelen had a nasty knock in his eye, looked like a boxer this morning so I think he forgot about all his previous problems. Apart from his eye – his vision is not perfect at the moment because of the inflammation – he’ll be fine and will be perfect to train tomorrow.
“Vincent Kompany reacted very well to his 20 minutes – that was always the plan. He is now fully fit and available for selection.
“We had to rely on our medical department to make big calls on players who weren’t fit for the start of the World Cup.”
