(First time posting, but i feel this may be newsworthy)
I see that Alex Rufer has posted a photo on his Instagram story captioned "Young boys win again" contains Myer Bevan wearing #30 and another unknown player wearing #12 with his face blacked out.
Possible unnamed trialist???
Might've just been one of the older players, or perhaps Bevan.
edit: actually, I can see Bevan in there - I assume one of the older guys filled in. No idea.
