I don't think anything has been said, but he has been kept to limited runs 3/4 times a year due to a history of injuries though I don't know what specifically.
Was wondering the same thing, hope he gets better soon?? Saw Zara on TV speaking about not going to Olympics and she seems really nice and very concerned for TT
She is alwasy most unassuming and seems to have a similar philosophy to Mary King, who smiles whatever may go wrong.
I would not class Zara as a 'professional' although she may be able to train etc almost full ltime, she is not under the pressure that is dependent on success for her living, business and roof over her head.
LCOBBY that is a bit of a daft thing to say....its like saying a professional Racehorse trainer is not a pro becasue they are already a multi millionaire (I am thinking of Terry Mills here)
Of course she is a pro, unless you get amateurs riding for England and winning at top level...
