Denmark's Christian Eriksen may have to stay in hospital for two more days but is making a good recovery, his agent said on Monday.
Eriksen collapsed during Saturday's European Championship game against Finland in Copenhagen and doctors think he had a cardiac arrest. He was resuscitated on the pitch.
"He has been joking, he was in a good mood. He is fine," the Inter Milan player's agent Martin Schoots told the Gazzetta dello Sport newspaper after visiting him.
"We all want to know what happened, he as well. The doctors are doing lots of tests and that takes time."
The 29-year-old is not expected to play again in the tournament but could continue his recuperation at home soon.
Eriksen will stay in hospital in Copenhagen on Monday "and perhaps also Tuesday" added Schoots.
Messages from across the world
"He is happy because he has seen how many people care about him. He has had messages from across the world," he added.
Denmark, who lost 1-0 to Finland having decided to restart the game hours after his collapse, meet favourites Belgium in their second Group B game on Thursday.
"Without a doubt he wants to support his team against Belgium as a fan," said Schoots, without specifying whether that would be in the Parken Stadium in the Danish capital.
Team ready to meet Belgium
Denmark's coach Kasper Hjulmand at first supported the decision to resume the Finland game but his players clearly suffered and now he believes they should have taken another option.
Thursday's Belgium game will go ahead as planned though and players feel they will be ready.
"We will play for Christian and for everyone who has supported us," Denmark midfielder Pierre-Emile Hojbjerg told reporters.
Striker Martin Braithwaite added: "We have felt the support from everywhere. And we appreciate that very much. I know that Denmark stands for standing together in adversity. And I have no doubt that people will see something special at Parken Stadium on Thursday.
"I'm looking forward to that and will definitely use it as motivation to play football for Christian."
