And linked to the comment about the IOC being backed into a corner, I've just been looking up why the men boxing tonight were not wearing protective headgear. It's apparently no longer mandatory for male boxers in the Olympics because research has indicated that concussions are more likely if the boxer wears it. However, this research was apparently only conducted on men, and there are insufficient data to know the risks for women (why does this not surprise me?). This is apparently why you see the male boxers in the men's event fighting without headgear and the boxers in the women's event wearing it.
So, women boxers may be competing in kit that actually increases risk of head injury (we just don't know) while they are being hit, especially by stronger men.
The powers-that-be are promoting the research that concussions are more likely for men if they wear headgear but in Paris, because of the rules, they now have men who have to wear headgear because they are competing in the women's event. Presumably these men are at lesser risk because their opponents are biological women so don't hit as hard.
It's hypothetical since Khelif and Yu-ting are in different weight categories but what if a biologically male boxer were to draw another male boxer in the women's competition? The IOC would be forcing these men to do something with an acknowledged risk to males.
