Christian Eriksen received urgent medical attention after collapsing on the field during Denmark’s European Championship game against Finland in Copenhagen.
Eriksen, 29, fell to the ground near the sideline late in the first half and was immediately surrounded by medical personnel.
His teammates formed a wall around him to give him privacy as the medics treated him.
Finland’s players then left the pitch as the match was suspended, with the score goalless.
Eriksen was eventually carried off to a loud ovation.
UEFA tweeted on Saturday evening: “The UEFA EURO 2020 match in Copenhagen has been suspended due to a medical emergency.”
BBC One ended their broadcast of the match in light of the incident.
Eriksen plays for Inter Milan in Italy and previously spent seven years at Tottenham Hotspur.
