Jockey Tom Marquand, who sustained a concussion after parting ways with his mount in Australia on Saturday, underwent shoulder surgery as a result of the incident, as well on Wednesday.
Marquand was forceably removed from his mount in the A$2-million Inglis Millennium due to interference from another rider, and was originally diagnosed with just a concussion. Subsequent MRI scans revealed a dislocated sternoclavicular joint.
“It has basically dislocated backwards, so I have to go for an operation today [Wednesday] to get it wired back in,” Marquand said in a video posted to Instagram.
“I will probably spend a week here now in Australia just because I can't fly straight after having an operation.
“Then the plan will be to come back to England and go through my rehab there and hope that I can get back in action by the time the last couple of days of The Championships are on and all being well, head back down to Sydney.”
Marquand's wife, fellow jockey Hollie Doyle, is also on the sidelines after dislocating her elbow last month, and she is set to have surgery next week.
He added, “Hollie is having a bit of a shocker as well, off with her elbow and she is going under the knife I think early next week.
“We will be in rehab and recuperation together and be a right pair so at least we've got two arms between us. It's obviously not ideal what's going on, but I think we can both count ourselves pretty lucky in the circumstances.”
