A UFC fighter and two of his cornermen had tested positive ahead of Saturday’s pay-per-view event in Jacksonville. Hours later, when the situation became known publicly, many people assumed the show would not go on. After all, the NBA immediately shut down in March when Utah Jazz center Rudy Gobert became the first of its players to test positive. A zero-tolerance policy is understandable, then and now, but what Silver and UFC President Dana White came to realize is there is also likely no realistic pathway for the return of major sports competition if that is the benchmark.
