I can't find anywhere that says Messam is not allowed to compete ...
Practically I am unsure how it would work. Even if he got on a plane this second, he would arrive and pretty much have to walk on the field right?
He's already in Rio. Just not 'officially' part off the NZ Olympics team.
And we're not out of it yet. Have to beat GB and hope Kenya can beat Japan. So the patient isn't dead, but better warm up the defibrillator!
