Last year’s Coventry Stakes winner Rajasinghe has been ruled out for the rest of the season.
Richard Spencer’s flag-bearer had failed to sparkle in the 2000 Guineas but it was thought that stamina was the main issue.
He was being aimed at Royal Ascot once more, with either the Commonwealth Cup over six furlongs or the Jersey Stakes over seven as his target.
However, those plans have now had to be shelved after he suffered a setback.
“We are obviously disappointed not to be heading back to Royal Ascot with Rajasinghe, but we have a strong team heading to Ascot nonetheless,” said Spencer.
