Just caught up on this thread.
I had a horse with him earlier in the year before I sold so I feel I know him quite well.
There was a reference to this being his 3rd and 4th incident? If that's the case... I know what the first two were. He was given two horses by an owner, and the previous trainer got the shits and gave them something so when they raced it was positive.
I know that story sounds like a load of BS in the current situation - but I'm aware of some very heated conversations between him and the previous trainer and believe it to be 100% true.
I don't know a whole lot about the racing industry, but if that was used in this decision it's pretty bad luck.
That being said - he broke the rules. My only issue is how many others do it and never get in trouble? My guess would be a lot.
Anyways, I think Darryl is a great guy regardless, and I hope he comes back strong and can recover from this massive PR hit.
