Ryan Moore has confirmed he suffered a broken wrist in a fall at Warwick on Tuesday evening.
The jockey currently heads the standings in the race for the Jockeys' Championship but it would seem his title hopes have suffered a fatal blow.
Moore was partnering Cresta Star in Warwick's Chieftain Fabrics Handicap when his mount slipped up after the home turn and sent him to the turf.
The rider feels the condition of the track was to blame for the fall.
Speaking in his Betfair column, Moore said: "I had my third fall in as many weeks at Warwick last night - following on from Romeo Montague at Goodwood and Havana Gold in Deauville - and the bad news is that it is third-time unlucky and I have broken my left wrist.
"I don't know how long I will be out for, but I can tell you that I am not happy."
