Christian Eriksen, the Danish football player who collapsed on the pitch in his country's opening Euro 2020 game, said that he was doing "fine" in an Instagram post from hospital on Tuesday.

"I'm fine -- under the circumstances, I still have to go through some examinations at the hospital, but I feel okay," he wrote in a post accompanying a photo of him smiling and giving a thumbs-up.

In a scene that shocked the sporting world and beyond, the 29-year-old Inter Milan midfielder suddenly collapsed on the field in the 43rd minute of Denmark's Group B game on Saturday against Finland in Copenhagen.
