Denmark midfielder, Christian Eriksen is “awake” in hospital after collapsing in the Euro 2020 match against Finland, said the Danish Football Association.
The 29-year-old’s condition has been “stabilised”, according to tournament organisers Uefa.
Referee Anthony Taylor immediately called for medical support and Eriksen received treatment on the field.
Eriksen received CPR before the players were taken off the pitch and the match was postponed.
Uefa confirmed the match had been suspended because of a medical emergency.
“Following the medical emergency involving Denmark’s player Christian Eriksen, a crisis meeting has taken place with both teams and match officials and further information will be communicated,” it said.
“The player has been transferred to the hospital and has been stabilised.”
The incident happened as a throw-in was played towards him near the end of the first half.
His distressed teammates surrounded him and the shocked supporters in Copenhagen were visibly upset as the player was treated.
Saturday’s other Group B match between Belgium and Russia, scheduled for 20:00 BST, is set to take place as scheduled.
Eriksen’s club, Inter, tweeted: “Forza Chris, all of our thoughts are with you.”
Former team Tottenham said: “Get well soon, Christian. The whole Spurs family is with you.”
Last month, Eriksen helped Inter Milan clinch their first Italian title for 11 years in his first full season with the club, after joining from Spurs for £16.9m in January 2020.
The Ajax youth player spent seven years with Tottenham, scoring 69 goals in 305 appearances.
UEFA in another statement disclosed that the game will resume following a request by both teams.
“Following the request made by players of both teams, UEFA has agreed to restart the match between Denmark and Finland tonight at 20:30 CET.
“The last four minutes of the first half will be played, there will then be a 5-minute half-time break followed by the second half.
“The match had been suspended due to a medical emergency which involved Denmark’s Christian Eriksen. The player in now in hospital and in a stable condition.
“UEFA wishes Christian Eriksen a full and speedy recovery and wishes to thank both teams for their exemplary attitude.”
The game subsequently resumed at 7:30pm Nigerian time.
The match eventually ended in a 1-0 win for Finland after Denmark’s goalkeeper, Kasper Schmeichel, was unable to keep out Joel Pohjanpalo’s header following Jere Uronen’s cross.
The match was Finland’s first ever European Championship finals game.
