Kevin De Bruyne suffered a fractured nose and an orbital fracture to his eye socket during the Champions League Final.
De Bruyne, who collided with Antonio Rudiger in the match, is questionable for the European Championship.
De Bruyne could return for Belgium wearing a protective mask.
Belgium manager Roberto Martinez criticized Rudiger for the challenge.
“For me, it was excessive force and it was reckless. And it should have been a red card. Kevin is not a player that goes down for no reason. You can see the pain and it’s a swollen eye," said Martinez.
