In Johnson's sport, you're not supposed to bleed. If you do, then you are taken off the court, given a new jersey and the bleeding is stopped. Boxing is just a bit different. Although we have been told time and time again there is apparently no chance one can get HIV from being on the same court as Magic, boxing is far from a parallel case. Anyone who ever witnessed a boxing match knows blood is simply a part of the deal.
Blood is everywhere.
Even the winners often look like something out of a Freddy Krueger movie when the contest is finished. It isn't rare for ringside spectators to get splashed with some of the red stuff. This is obviously a reason for concern. Fortunately, Nevada has mandatory testing for the virus. But the state is one of only four that mandate boxers to have such testing.
