Belgium say De Bruyne is not "fit enough" to feature in Wednesday's match against Iceland, and the midfielder has now returned to Manchester City for further assessment.
Belgium manager Roberto Martinez played down the severity of the situation in his post-match comments after the England defeat.
"I would not say that Kevin is injured... he said he felt something," Martinez said.
"It is too early to know what he has, but he did not feel 100 per cent. It was rather a precautionary change."
De Bruyne is now a doubt for City's Premier League clash with Arsenal at the Etihad on Saturday, live on Sky Sports.
