And the Hoops star was labelled a 'superhero' by Brentford star Christian Norgaard for playing on through the pain.
Schmeichel injured his shoulder during Denmark's Nations League play-off defeat in extra time to Portugal in Lisbon. They will now be in Scotland's group in the World Cup qualifiers.
The veteran keeper played on despite the injury because Denmark had used all their substitutes Danish team doctor Morten Boesen revealed the 113-times capped star will get further tests.

"He is clearly in pain after a fall on his shoulder, so we are examining him further with an MRI scan."
He was spotted at Lisbon Airport on his way back with his arm in a sling and international teammate Norgaard was amazed that not only did Schmeichel refuse to come off, he even continued to make saves.
He said: "We had a goalkeeper out there who was like a superhero from another world.
"He runs around with one arm and yet he makes an incredible save.
"I'm disappointed, but there's also a proud feeling of having given one of the best teams in the world a fight to the finish. But that's probably the biggest disappointment right now."
