Group B's first match saw Denmark and Finland in Copenhagen but the match has been suspended due to an accident that happened to Denmark midfielder Christian Eriksen.
The match was Finland's first-ever European Championship appearance, which is an achievement in itself for Markku Kanerva's side.
Denmark have a history in this competition, famously winning it in 1992 and reaching the quarter-final stages in 2004. However, since then a group-stage exit in 2012 and failure to qualify in 2016 has soured the relationship.
The game went smoothly in the first half, but Denmark midfielder Christian Eriksen collapsed on the field in the final moment before the stop. After initial medical treatment, Eriksen was pulled off the ground on a stretcher.
Following the incident, UEFA confirmed that the match had been suspended. After Eriksen was taken to the hospital, UEFA later announced that his health was stable, and the Danish FA also confirmed that Eriksen was awake and undergoing further examinations.
Following the request of the players of both teams, UEFA agreed to resume the match between Denmark and Finland.
In the second half, the game was very soulless due to what happened until Finland scored the first goal in the 59th minute in Copenhagen. Pohjanpalo gets between two Denmark defenders and guides Uronen's cross past Schmeichel. Uronen sent a rare cross into the Denmark box from the left, and Pohjanpalo was left pretty much free to head in. Joel Pohjanpalo scored Finland's first-ever goal at the European Championships with their first shot in the competition.
Finland get a historic victory against Denmark in their first-ever appearance at a major tournament. Pohjanpalo scored the only goal with just under an hour played, with Hojbjerg missing a penalty for the home team 15 minutes later.
