Never once said the break didn't happen during the fight, just think its very strange that people are claiming to see things that very clearly didn't happen.
They are just trying to pinpoint when the actual hairline fracture first happened, was it when Conor hit the knee or elbow ? because when Conor kicks the knee Poirier points down telling Conor your injured, you could hear the sound of the kick bone on bone something happened at that point and according to the Doctor Conor didn't kick the elbow and that kick wouldn't cause a fracture anyway but he says that's his opinion but we will never know.
*UPDATE* on Conor McGregor BROKEN Leg, and What REALLY HAPPENED with the Checked Kicks?? - YouTube
Dr Brian says quote:
For those saying it was Poireir's left (hidden a bit) elbow they were referring to, I can't see any way the angle of Dustin's arm in that position breaks a tibia. The forearm is nearly parallel to McGregors leg and I can't see how Dustin's forearm wouldnt have actually broke instead if that were the case. Either way, well never know for sure, this cumulative mechanism is just my opinion.
Then the Doctor points to the training camps injury to the ankle as the possible first hairline fracture, but according to Conor's trainer it came back negative, the Doctor again says NO, this might not happen, but the Doctor could've missed it and sometimes they see certain things they can't make out what it is.
So my opinion is, it has to be because of weak bones due to lots of alcohol consumption and a poor diet and extreme weight cutting, causing calcium loss and problems with bone tissue regrowth, this could be the medical answer, unless that knee kick caused that hairline fracture without weak bone tissue problems, but the Doctor again says NO, so in my opinion alcohol has to be the cause because Conor is a heavy drinker, so Conor could've had weak bone tissue problems due to alcohol abuse and this would happen according to medical science.
So the slight kick to the knee caused the damage to already weakened bone tissue because of alcohol consumption, extreme weight cutting and bone tissue regrowth problems, Conor kicks the knee then Poirier points down to Conor's foot telling him I heard that, now your injured, the reaction video evidence is clear a pop happened during the fight after that knee kick.
There's no other possible answers it has to be weak bone tissue and bone tissue regrowth problems due to alcohol abuse and extreme weight cutting, these factors causes a weak tibia to fracture then finally brake after incorrect leg kicks.
