Eden Hazard sat out Belgium's training session on Tuesday after picking up an injury during the 4-0 victory over Hungary.
The 25-year-old injured his quadricep in the first-half but is expected to be fit for Friday's quarter-final against Wales in Lille.
"That's why I took him off," coach Marc Wilmots told journalists on Tuesday.
"I think he'll be back the day after tomorrow [Thursday].
"He's working with the physios and he should be 100 per cent on Thursday."
