Christian Eriksen says he is "doing well" and is at home with his family after collapsing on the field during Denmark's match against Ukraine on Sunday.

The 34-year-old spent the night in the hospital after the incident. In a statement on Instagram, Eriksen wrote that his "recovery has already started."

The match in Odense was stopped in the 65th minute when Eriksen collapsed and was later abandoned. He was able to walk off the field after regaining consciousness.

The midfielder was fitted with an Implantable Cardioverter Defibrillator (ICD) - a type of pacemaker - following a cardiac arrest during a Euro 2020 match against Finland in 2021. That device allowed him to resume his career with Brentford in 2022, eight months after the collapse.

"As you can probably imagine, receiving a shock from my ICD has had a major effect on both me and my family, but I want to assure everyone that this was a different situation from what happened in 2021," Eriksen wrote.

He expressed gratitude for the support from players and medical teams, and praised the doctors who managed his heart condition. "My ICD did exactly what it was designed to do: protect me when I needed it," he added.

Denmark national team doctor Morten Boesen confirmed that "the pacemaker responded as it should."

Eriksen, now playing for Wolfsburg, said his focus is on recovery, family, and vacation. "For now, my focus is on recovering, spending time with my family, going on vacation, and playing football with my children."

An ICD is a device about half the size of a mobile phone that constantly monitors heart rhythm and delivers a shock when needed to restore a normal rhythm, according to sports cardiology professor Aneil Malhotra.
