Henry Ceci lis mystified by the expensive defeat of his highly-rated colt Vacamonte at Sandown on Saturday.
Preliminary tests have revealed no obvious problem with the two-year-old, who started 1-4 favourite for Saturday`s Group Three Ford Solario Stakes only to trail in fifth of seven.
'Nothing has come to light,' the trainer said on Sunday. 'We scoped him and he was clear. He ate up and he is sound as a bell this morning.
But he is convinced there is a physical explanation for the dismal showing of his charge, who topped betting on next year`s 2000 Guineas after his winning debut in Listed company at Newmarket last month.
'The writing was on the wall four furlongs out, he had his head down and he looked as though he had a pain in his tummy or something,' Cecil said.
'Three and a half furlongs out he was a dead horse. He was a fit horse but he blew for 40 minutes afterwards so he wasn`t right.
'He is a very genuine horse and that wasn`t him at all. There must have been something causing him distress.
'We will do a blood test but only time will tell.'
Saturday`s race was won by King`s Ironbridge, who had finished only fifth behind Vacamonte at Newmarket.
