Thornton set to make comeback.
Alan King's stable jockey has been out of action since December 11 with a fractured arm, but been given the all-clear to resume his season.
He tweeted: "It's official cleared to ride from Tuesday 14th."
King was delighted at the news and was amazed at the speed of Thornton's healing capabilities.
"The good thing is that the horses seem to be still in top order and we received some more encouraging news this week when Thornton got the all-clear to return to race riding at Folkestone next Tuesday," said King.
