George Baker remains in intensive care in a Swiss hospital after a horror fall on the ice 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 of the day.
Two other horses came down in the incident but neither they nor their jockeys were seriously injured.
Baker was taken to a trauma hospital in Chur and the rest of the meeting was abandoned. Following a track inspection, a crack was found in the ice.
The jockey's agent Guy Jewell said: "There's no real update today. He is still intensive care and he's been sleeping a lot.
"I think it's just day by day and he's not been moved today."
