De Bruyne will take a while before he is back to full health.
The Belgian midfielder has injured his nose and eye socket after clashing with Antonio Rudiger in the Champions League final in Porto.
He underwent a minor surgery that allowed him to play on the grounds but he is playing through pain in the Euros and would have to continue to do so for a while.

De Bruyne told reporters on Thursday: “I don’t feel anything on the left side, like after a visit to the dentist.
“My nerve is very badly affected, which could take six months. It’s not a comfortable feeling, but the most important thing is that I can play.
“The last two months have been up and down for me with minor injuries. After that fracture in the nose and eye socket, it was a bit of a wait.
“But luckily I came back in the fastest way. There was very good intensity for half an hour, [against Denmark] then I felt it. But I’m glad I was able to play.”
