When Denmark's star man Christian Eriksen dropped to floor in his side's tournament opener against Finland, football ceased to matter, as the nation's talisman battled for his life after suffering a cardiac arrest.
Thanks to the heroics of the medical team and skipper Simon Kjaer, the ex-Spurs star is now out of hospital and recuperating, and his teammates are now ready for their Euro 2020 semi-final, after fearlessly pushing on in his absence.
Here's a look at five key Denmark players who England will need to watch out for, as the two sides prepare to do battle at Wembley Stadium:
1. Thomas Delaney
The Borussia Dortmund midfielder was outstanding in his side's gusty 2-1 quarter-final win over the Czech Republic, dominating his opponents in the air, tackling relentlessly, and scoring the opening goal of the game to put his side in the driving seat.
A real midfield general, Delaney will be looking to set the agenda, and it will be up to Declan Rice and Kalvin Phillips to press him relentlessly wherever possible.
2. Joakim Maehle
At every major summer tournament, there's always player or two who subsequently secure big transfer moves to reward their efforts, and Denmark's flying wing-back is a fine candidate to do just that this time around.
His stunning assist against the Czechs will give England plenty of cause for concern, and Kyle Walker, who's had a few defensive lapses in the tournament so far, will need to wary of the threat Maehle's pinpoint crosses possess.
If England stick with a back four, he'll be a real danger on the overlap, that's for sure.
3. Kasper Dolberg
England's defence have not conceded a single goal in the tournament so far, but could Dolberg be the man to tarnish England's clean sheets? Quite possibly.
The 23-year-old was tipped as the 'next big thing' after impressing at Ajax in his teens, but is still looking to really make a real breakthrough at club level, and scored just six times for Ligue 1 side OGC Nice last season.
However, he's looked a new man in a Denmark shirt at Euro 2020, scoring twice against Wales and once against the Czechs after bringing out the magic in the knock-out stages.
4. Mikel Damsgaard
Sampdoria's attacking midfielder has been highly consistent for Denmark throughout the tournament, and, like Dolberg, looks to be saving his very best form for the knock-outs.
His positional awareness and ability to find space is troubling - from an England perspective, that is - to say the least, and you can just see him coming out of nowhere to grab a goal on Wednesday.
A dynamic dribbler bursting with flair, the 21-year-old is one of his side's most deadly weapons going forward.
5. Andreas Christensen
Fresh off the back of winning the Champions League with Chelsea, Christensen, a player transformed under Thomas Tuchel, is in the form of his life.
He's part of a rock-solid back three, and has the composure and ball-playing nous to frustrate England's attackers.
On top of that, he scored one of the goals of the tournament in his side's blockbuster 4-1 win over Russia that saw them escape Group B.
