The Danish FA confirmed his implantable cardioverter defibrillator activated as intended, five years after his cardiac arrest at Euro 2020.
Eriksen, 34, appeared to grab his chest before falling to the ground in the 65th minute at Nature Energy Park. Norwegian referee Sigurd Smehus Kringstad halted play immediately and medical staff attended to the midfielder on the pitch. The match was abandoned in the 79th minute — with Denmark leading 2-1 — after the referee spoke to both coaching staffs.
Danish national team doctor Morten Boesen issued a statement with the most critical update.
"Christian is doing well and walked off the pitch by himself. As I see it, the pacemaker responded as it should. He was briefly unconscious, but regained consciousness very quickly, and we were quickly in contact with him. He will now undergo further examinations at the hospital to determine what caused the incident."
He added: "Christian is doing well, and he asked me to send his regards to all the players and tell them that he was OK."
Eriksen was making his 151st international appearance for Denmark and his first start since joining VfL Wolfsburg, for whom he made 34 appearances during the 2025-26 Bundesliga season after leaving Manchester United.
Denmark captain Pierre-Emile Højbjerg described the moment he saw his team-mate go down.
"There's a throw-in, and then I go out to the side. I turn around a bit, and I see Christian on his way to the floor, and we know a little about how he reacts, what that means. Everyone reacted super-fast and with respect. I can only compliment how much courage those who took care of Christian on the field had."
Head coach Brian Riemer spoke to both sets of players at the centre of the pitch after the abandonment, with players from Denmark and Ukraine standing arm in arm around him.
"The most important thing is that Christian is doing well and he is. He has left the field, and he has sent his regards to the players. Now it's about us standing together, as you could see that we did in the most dignified way on the field, and of course ensuring that everyone has a shoulder to lean on from here."
The ICD was fitted eight months after Eriksen's cardiac arrest during the Denmark-Finland Euro 2020 group match in Copenhagen in June 2021. It allowed him to resume his playing career at Brentford in January 2022 and subsequently at Manchester United, where he spent three seasons before his Wolfsburg move.
