Denmark vs Finland
In the 43rd minute, the match was suspended after Danish midfielder Christian Eriksen collapsed on the pitch due to a cardiac arrest. Eriksen was transferred to Rigshospitalet where he was stabilised. UEFA gave the players two options for restarting the match, either to resume later in the evening or the next day at 12:00 CEST. Only after receiving confirmation that Eriksen was awake, the Danish team agreed to continue the match that evening. The match was resumed at 20:30, with the last four minutes of the first half to be completed prior to a five-minute half-time break.

Discipline
Fair play points were to be used as a tiebreaker if the head-to-head and overall records of teams were tied (and if a penalty shoot-out was not applicable as a tiebreaker). These were calculated based on yellow and red cards received in all group matches as follows:
 * yellow card = 1 point
 * red card as a result of two yellow cards = 3 points
 * direct red card = 3 points
 * yellow card followed by direct red card = 4 points

Only one of the above deductions would be applied to a player in a single match.
