Quote: rugbyleague88 "Are we at the stage now with Gannon where another head knock is game over or does the prolonged lay off mean that next time he has a head knock, his slate has been wiped clean and he can be treat like Handley or Miller were they to have a head knock?'"
How the club would choose to manage it and the game's protocols might be two different things.
I think the bigger question might revolve around how often the decision needs making.
To quote Barry McGuigan "once you've lost that ability to take a shot you never, ever get it back". I think he's spot on wrt boxing but not sure about RL. My guess is that there are some players that are susceptible to being concussed though probably a lower percentage than in boxing. I'm not talking about Morgan specifically in this last bit I should add - hopefully his recovery is now complete.
