Shortly after being given the all-clear to start in the Blamey Stakes, Best Of Days has had his campaign shut down by a bleeding attack.
The Godolphin horse went to Sandown on Thursday for the second of two enforced jump-outs after staying in the barriers in the Futurity Stakes at Caulfield last Saturday.
He had passed the first test on Wednesday and successfully completed the second before the bleed was discovered.
Trainer James Cummings reported the incident to stewards and the Group One winner of the Cantala Stakes will now serve a mandatory three-month ban.
Jockey Brad Rawiller will now have to wait until next week to make his comeback from a serious neck injury.
