It's up to the club to inform the public about such matters, and because Liam is my mate, I am also aware that I have a responsibility to respect his privacy, especially concerning his health.
However, I think I should set a couple of things straight before panic sets in. Firstly, he and Bell will both be having some work done on their shoulders tomorrow. Secondly, while he'll be out of action for a while, he will definitely be back playing mid season, so talk of his demise is definitely premature. Believe me, he'll be back stronger and hungrier than ever.
