Is there a reason why camera crews, both motion and still, need to be present for these weigh-ins? I'm proud of my body and don't mind showing it at appropriate times, but I would probably cover my junk in this scenario, too. He's having a weigh-in, not posing for a nude photo shoot.
and there are a lot of people at the weigh-ins. its like the last chance to get one up on your opponant before the fight.
cameras are everywhere these days especially where sport is concerned
