I supect that he may have uncontollable urges to get his thumbs out and start dancing round his computer..
He was going through some serious personal **** when he wasn't in the team. Sound now. No surprise his last couple of appearances have been better. Reckon he'll go from strength to strength now but Hendo still deserves to be in CM ahead of him and its not right BR hooking him for his favourite when, on merit, Henderson deserves the shirt.
He has a Grade III Acromio-clavicular separation. Which, after a bit of googling, appears to be 50/50 as to whether it heals itself or surgery is required. Grade II = No surgery. Grade IV = Defo surgery. Joe's must not of healed satisfactorily on its own, so having surgery instead.
