Last night saw Serbia's home tie against Albania postponed by referee Martin Atkinson just before half-time after a massive skirmish broke out on the field.
The two nations have a fierce rivalry and Uefa has banned Albanian fans from attending the game to avoid crowd trouble.
But somebody decided they would be in attendance. A drone was flown overhead with an Albania flag and message attached to it. When Serbian players got hold of the flag they were confronted by Albanian players.
What happened next was madness. Serbian fans and stewards began fighting with the Albanian players, many of whom have since been snapped with black-eyes and facial injuries from the attack. Bekim Belaj was hit with a chair while Lorik Cana was reportedly punched several times by a steward after he confronted a fan.
One player in attendance was Chelsea defender Branislav Ivanovic.
He is of course Serbia's captain and he was clearly upset with the way the tie ended. He was quoted as telling the media after the game:
"What happened is something we can't comprehend at the moment. On behalf of my team, all I can say is that we wanted to carry on and that we shielded the Albanian players every step of the way to the tunnel. The Albanian team said they were unfit physically and mentally to carry on after talking to the officials and they will now decide the fate of this match. We can only regret that football took a back seat but it is difficult to draw any conclusions or make any comments now."
Ivanovic seemed desperately disappointed with the way the game ended for him and his nation last night. Uefa will now decide the outcome of the game. It could be it is played again behind closed doors or that the points are awarded to one or both teams after the clashes.
But Chelsea fans will be pleased to know Ivanovic is unharmed and ready for Premier League action this weekend.
Where you can probably rest assured that a similar circumstance will not present itself.
