British jockey George Baker is reported to be facing "a long rehabilitation process" after suffering bleeding in the brain after a fall on the ice track at St Moritz.

Baker, who won the St Leger last September on Harbour Law, was riding Boomerang Bob for Jamie Osborne on the frozen lake track when the horse was brought down and fatally injured in the first race last Sunday.

Two other horses came down in the incident but neither they nor their jockeys were seriously injured.

Baker was airlifted to a trauma hospital and has remained in intensive care all week, undergoing a MRI scan on Friday which revealed the bleeding in his brain.

"George will remain in hospital in Switzerland whilst arrangements are made for his return home to commence his rehabilitation," a statement from the Professional Jockeys' Association said.

"...George has suffered from some bleeding in the brain and we are anticipating a long rehabilitation process, but are hopeful that he will make a positive recovery.

"George's family would like to express their thanks for all the kind messages of support and would appreciate privacy at this difficult time."
