Robert Thornton hopes to return to action in about a week to 10 days after escaping with a minor back injury following a crashing fall at Leicester on Tuesday.
The jump jockey was allowed home today after being detained overnight in Leicester Royal Infirmary for tests.
He took a heavy tumble at the third-last fence from Cracboumwiz, trained by his boss, Alan King, in the Dick Christian Novices' Chase.
"He has a minor back injury, nothing too serious. He's gone home, but he's very sore and severely bruised," said his agent Dave Roberts.
"He will probably have to take a week to 10 days off. It's nothing major and he'll be back as soon as he can."
Thornton should have been on duty today at Huntingdon and misses the ride on JCB Triumph Hurdle favourite Mille Chief in division two of the Huntingdon Racecourse For Outdoor Events Novices' Hurdle.
