The Denmark and Inter Milan midfielder received emergency medical treatment on the pitch on Saturday after collapsing during the first half of his team's Euro 2020 match against Finland in Copenhagen.
Later that day, the Danish FA said that the 29-year-old was awake at the nearby Rigshospitalet, where he was being examined.
Issuing an update on Sunday morning, the Danish FA (DBU) said that the former Tottenham Hotspur and Ajax player had sent greetings to his Denmark team-mates and is undergoing further tests.

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."
