How and when did Doyle realise it was a 2 horse race (one you say he was 1/4 to win)? Maybe he had the benefit of hindsight like you Gingertipster 
I am always puzzled why any punter would show concern for jockey safety and "possible" serious injury caused by reckless riding, don’t think jockeys would put up with dangerous riding from each other and there’s always the failsafe of the stewards and authorities watching on.
After all Gingertipster, how many jockeys have suffered serious injuries in the last 10 years in Britain caused by dangerous riding from other jockeys?
