I can see the argument that you want him to avoid it, but is it really to his benefit and the Jazz benefit? Sure, there's risk he could get injured. But there's always that risk.
That's my problem with this argument that they shouldn't compete in these summer tournaments/Olympics. These guys are going to play somewhere. Who's to say that playing pickup ball isn't going to cause the same type of injury.
PLaying in the olympics could get him back into the swing of things faster so his start to next season is smoother.
