Jockey Frankie Dettori will miss the rest of the season with a fractured right ankle, his business manager told the Associated Press Oct. 2.
Dettori, 42, who was slated to ride leading Prix de l'Arc de Triomphe (Fra-I) contender Treve in the Oct. 6 event at Longchamp, was unseated from his mount Eland Ally before a race at Nottingham Oct. 2.
According to Racing Post, trainer Criquette Head-Maarek said Thierry Jarnet will replace Dettori on Treve.
Peter Burrell, Dettori's business manager, told the Associated Press, "It's an extremely painful injury. Sunday is out—as is the season.''
