Rostropovich remains in a veterinary clinic after suffering a pelvis injury in the Melbourne Cup, but the Lindsay Park stable has given a positive report on his condition.

Five-year-old Rostropovich, trained by Lindsay Park's David and Ben Hayes and Tom Dabernig, finished a long last in Tuesday's Melbourne Cup at Flemington after being eased down by jockey Dwayne Dunn.

Racing Victoria said on Tuesday afternoon that vets at the University of Melbourne Equine Centre determined the horse sustained a stress fracture in his pelvis.

Lindsay Park Racing posted on Tuesday the prognosis for a full recovery was good and on Wednesday reported the horse was making excellent progress.

"Rostropovich continues to make excellent progress under the care of the team at U-Vet Werribee Equine Centre," Lindsay Park Racing said on Twitter.

"He is comfortable, bearing weight on all four limbs and eating and drinking well. The outlook is very positive."

Rostropovich was running in the Melbourne Cup for the second time having finished fifth in 2018 when trained by Irishman Aidan O'Brien.
