Warren Marston will miss his rides at Huntingdon today as he is feeling the effects of a fall at Ludlow on Wednesday.
The jockey was hurt when Strong Magic came to grief in the Elm Novices' Chase.
Marston's agent Chris Broad said: "He took quite a hefty fall from Strong Magic.
"He did ride again that day but in a lot of pain.
"He was too sore to ride today, he's done no damage but he can't put his foot to the floor. The plan is for him to ride tomorrow."
