I've probably watched the fight more times than you lol. He does put weight on his foot. He LITERALLY stomps his feet before the fight starts. That's not something someone does with an ankle injury.
The one time he 'rolled' his foot was when he cancelled a teep kick due to Khabib backing out of range.
The problem with actually engaging in this 'balloon foot' argument is I don't really know if you're trolling or actually being serious, since >90% of the time it's trolling.
If Conor's foot was actually injured, why did he not post any dated x-rays? It's really that simple lol.
