Ruby Walsh is expected to be fit to ride on Saturday despite being stood down after a fall at Newbury on Friday.
Walsh suffered a fall aboard Curtain Razer in the Pertemps Handicap Hurdle, with the racecourse doctor ruling him out of his two remaining rides on the card.
The jockey is planning to be back in action on Saturday, with Tidal Bay in the Hennessy and Big Buck's in the Long Distance Hurdle the pick of his Newbury rides.
Clerk of the course Richard Osgood said: "He's got a sprained thumb and was stood down today, so he will have to be checked over by the doctors in the morning."
Timmy Murphy was taken to hospital for precautionary X-rays after taking a heavy fall at Newbury.
Murphy was partnering Leeroar in the closing Inkerman London "National Hunt" Maiden Hurdle when the duo fell at the third flight.
A racecourse spokesman said: "He has been taken for precautionary X-rays on his back."
Murphy is due to ride The Package for trainer David Pipe in Saturday's Hennessy Gold Cup at the Berkshire venue.
