Leading jockey Robert Thornton looks set to miss next week's Cheltenham Festival and the rest of the season due to injury.

Thornton suffered a heavy fall when riding Our Phylli Vera for his boss Alan King at Southwell on Monday, but his injuries were not thought to be serious and he was expected to be in action at Exeter the following day.

However, he did not take up his one ride at the Devon track and has since undergone tests, which revealed bad news.

Thornton tweeted: "Few tests yesterday, not great news looks like I'll be missing the rest of the season."
