Seems strange that he was put down without consulting with the owner. It also can't have looked that bad a fall if they were waiting for him to run in at the end?
The fall at beechers (the one that the owners would have seen on tv) wasn't 'that bad', however as previously stated, the jockey less horse then fell again at the 11th, which they may not have seen, and it was that fall that let to the putting down of a champion. Well that's what I think may have happened.
