Harry Skelton will miss the Scottish Grand National meeting after he injured his shoulder in a fall at Cheltenham.
The top jockey came off Heltenham in a race on Wednesday and gave up the rest of his rides on the afternoon.
Skelton, 33, will visit a specialist on Friday to see whether he can make it back for the end of the jumps season. His wife Bridget Andrews will take his place on most of his scheduled rides tomorrow at the Scottish track.
