Is it a cast or a splint?
I have not seen a diagnosis for that injury, has anyone read that it is a fracture? could be a sprain, he might play then.
Gee it would be exciting if MGT gets a run, big decision on where to play him since he is legit a Wing/Center.
Personally I would be happy to see him run out in either or position.
He is a big lump of lard, built like
Tony Kemp in Kemp's playing days (shouldn't need to qualify that but round here you have to dot your 'I'(s) and cross your 'T'(s).
With a build like Moala's unless he changes it radically, his future is more likely at Center than Wing, which is why I lean that way if I had to choose.
That said, as he gets fitter, he could be a handy kick returner.
