If you don't know, talk to Black fighters who've spoken out about it. Is UFC's Code of Conduct even a thing anymore? Racism wasn't even the line. It was "any statement that would "bring disrepute, contempt, scandal, ridicule or disdain." Total abdication of responsibility here.
Re Cormier-
So there's a big difference between blurry vision and "I can't see anything, it's all black".
Something called a hyphema where blood collects in anterior chamber of the eye and can block vision would be near top of my list and if so is emergency evaluation
