Later that day, the Danish FA said that the 29-year-old was awake at the nearby Rigshospitalet, where he was being examined.

The DBU added that Eriksen's team-mates had received crisis assistance in the wake of the incident, which had left players from both teams in clear distress.
After Eriksen collapsed, his team-mates formed a shield around him while he received treatment and fans from both sets of countries chanted the name of the midfielder.
"We would like to thank everyone for the heartfelt greetings to Christian Eriksen from fans, players, the royal families from both Denmark and England, international associations, clubs etc," the DBU said.
"We encourage everyone to send their greetings to the Danish FA, where we will make sure they are all passed on to Christian and his family."
The Group B game had initially been suspended but then it was decided that it would resume at 8.30pm local time, with the Finnish side winning 1-0.
