Cheating seems easy to deal with. The players should go into a dressing room with supervision. They take off all of their clothes and don new clothing for the event. They then go out and play. They also probably need to be accompanied to the bathroom with an observer.

Of course, this all sounds crazy. But it's not that different than what athletes have to do (if you've ever had to stand around naked waiting to pee into a bottle after a race you know what I'm talking about).

Yes, they still could have some kind of in-body thing (tiny earpiece, or weirder thing in some other part of their body), so they probably have to also be scanned for electronics (or, the game has to take place in a location where there is no way to electronically communicate).
