Frankie Dettori dismisses retirement rumours and insists 'I will race on and fight on' Dettori, 41, has been passed over for Godolphin's lone runner, Kailani, in Friday's Investec Oaks, with 20-year-old Mickael Barzalona being preferred. That was seen as confirmation that Dettori was no longer the automatic No 1 choice with Godolphin after being their first jockey for nearly two decades. On Wednesday night, Ballydoyle revealed that Camelot and Astrology were both certain to run in the Derby at Epsom on Saturday, but decisions on Imperial Monarch, Tower Rock and Father Of Science will be taken on Thursday.
