Danish midfielder Christian Eriksen collapsed while playing and was given CPR by medics during his side's Euro 2020 clash with Finland on Saturday, and the match has been suspended.
A Reuters photographer at the game saw Eriksen raise his hand as he was carried from the pitch on a stretcher.
He has been taken to hospital in a stable condition, according to UEFA.
Eriksen collapsed suddenly while running near the left touchline. The midfielder's teammates formed a ring around him as medics pumped his chest just before halftime in their Group B clash.
Both teams subsequently left the field with officials holding up sheets to hide the stricken player from view.
