Just to make a comment on the heat in the arena. I live in Abu Dhabi (I'm actually 20 minutes from 'fight island') and the heat is pretty nasty during the summer. I was at the Khabib/Poirier fight and it was hot but I think this fight will be more favorable for the fighters. Reasons why:
- Early morning fight times
- Air conditioned arena (I presume it will be a much smaller setup so easier to cool)
- No fans
- I presume some fighters may come early to acclimatise if allowed which will reduce the effects come fight time
All of these should contribute to the heat having less of an effect on the fighters. So I would take the heat into consideration but not massively.
