When Juan Manuel Marquez connected with what was destined to become one of the most famous punches in boxing history it was as if time had stopped.
The once seemingly invincible Manny Pacquiao fell to the mat in a heap, was knocked unconscious and for a few moments it seemed like we have collectively fallen into some sort of alternate reality.
For two fighters who in their previous 36 rounds had maybe three or four that could be scored decisively, this ending seemed impossible.
It was the proverbial bolt from the blue, the lottery shot, the home run, the Hail Mary or whatever other sports cliche you want to insert here.
And it ended the fight and more importantly it shook up the entire boxing world.
It also left us with clear winners and losers which go far beyond the two men in the ring. Its reverberations are sure to be felt in the coming months and we'll assess some of them here.
