I dont know the current situation in the US, but is it allowed to gather in such a big crowd right now? What about 2-meter rule?
About the fight - previously, Masvidal was on a short notice (if I'm not mistaken 10 days only) and managed to break Usmans nose. In social media, Masvidal likes to display that, saying if he had a full camp, he would have bitten Usman. Now he has a chance to prove that
In an article by Brett Okamoto of ESPN from January he (Usman) stated that he had actually shattered his nos in the training camp prior to the first Masvidal fight. We can take his word for it and we might not, but we can also take Masvidals word for believing he would be more ready if he had a longer camp. If the fight was more closer then we could entertain that idea, but Usman completely dismantled Masvidal and I can't really stand behind that idea.
