The Ultimate Fighting Championship plans to hold a pay-per-view event on tribal land in central California this month, an attempted end run around widespread federal and state guidelines against holding large gatherings during the coronavirus pandemic, according to three people familiar with the decision. Even as most sporting events have ground to a halt worldwide because of the highly contagious virus, Dana White, the UFC president, has insisted he can safely hold mixed-martial arts events. “This place where this fight is going to be on April 18 I have locked up for two months, so I’m going to continue to pump fights out,” White told ESPN on Monday, though he declined to say exactly where. The location will be the Tachi Palace Casino Resort near Lemoore, California, about 40 miles south of Fresno, according to the people, who spoke on condition of anonymity because White had not announced the venue.
