AN explosive post-race bust-up between jockeys saw one rushed to hospital for treatment.
Stewards have opened an urgent investigation into the 'physical altercation' between two top-tier riders.
Group 1-winning superstar Noel Callow, who has won more than £22million in his career, was involved.
As was fellow top level-winning rider Kyle Wilson-Taylor, report Racenet.
Their scrap was said to have erupted during a heated argument after a race at Doomben in Australia on Wednesday.
Kim Kelly, Deputy Commissioner for the Queensland Racing Integrity Commission, said: "I can confirm that a stewards’ enquiry has been opened into a physical altercation between two riders at the Doomben race meeting.
"A considerable body of evidence has been taken and the matter was adjourned to a date to be fixed to allow a rider who was taken from the course for medical treatment to give evidence."
Racenet report that Wilson-Taylor, 25, insisted he did not start the fight.
'King' Callow, 49, who became a Uber driver during one break from the sport, has been stood down for medical reasons.
It is believed that Wilson-Taylor is fit and well enough to continue riding pending the outcome of the probe.
