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 Inter Milan player's condition has "stabilised", according to tournament organisers Uefa.
The game in Copenhagen was suspended before half-time after the former Spurs playmaker fell to the ground and was given emergency treatment on the field.
Finland won the Group B match 1-0 after it restarted at 19:30 BST.
Danish players were applauded on to the pitch by their opponents as they returned to the field to resume the game.
Uefa said it agreed to restart the match "following the request made by players of both teams".
The final five minutes of the first half were played, before a five-minute half-time break and the second half.
Peter Moller of the Danish Football Association told Danmarks Radio: "We have been in contact with him
and the players have spoken to Christian. He is doing well and they are playing the match for Christian".Denmark head coach Kasper Hjulmand was in tears at the post-match news conference.
"It was a really tough evening, on which we've all been reminded what the most important things in life are. It's meaningful relationships. It's those people who are close to us. It's family and friends," he said.
"Everything, everything, everything - all thoughts are with Christian and his family."
Uefa president Aleksander Ceferin said: "Moments like this put everything in life into perspective. I wish Christian a full and speedy recovery and pray his family has strength and faith.
"At these times, the unity of the football family is so strong and he and his family carry with them the good wishes and prayers of everyone. I heard of fans of both teams chanting his name. Football is beautiful and Christian plays it beautifully."
Saturday's other Group B game between Belgium and Russia took place as scheduled at 20:00, with Belgium winning 3-0.
Belgium striker Romelu Lukaku, who scored twice, paid tribute to his Inter team-mate on opening the scoring, saying to the TV cameras "Chris, I love you".
