I was told on Saturday that he has to retire for the good of his own health, basically he needs a hip replacement.
I think it'll be covered by his/Wigans insurance. Didn't that happen to Sam Burgess and Greg Inglis and in Inglis's case is the reason he can't play again in Australia?
As for the size of the forwards Byrne is 6'3", Kilner 6'4", and Havard 6'4. Both Byrne and Kilver are over 17 stone. Havard would have walked young player of the year had sadly he got injured.
