Just for the record, Sam has a bionic or cochlear implant which he wears whilst playing hence the helmet to protect it. He can hear and will continue to play with it whilst at Collingwood like he has throughout his junior footy - it's no different to a player who wears glasses, would it be assumed in that case that he/she would play without contact lenses and therefore be at a disadvantage and a liability? The answer is no and it's no different with Sam.
A bionic ear and contact lenses are the same thing? TIL
