Dettori was penciled in for four rides on the
opening day, including King's Stand Stakes favorite Lady
Aurelia, who will now be ridden by John Velazquez.
"I've been trying so hard to get fit for today but had to accept
this morning it wasn't going to happen," the 46-year-old said on
Ascot Racecourse's Twitter account.
"I've got to have Physio and get it properly looked at so won't
be at Ascot this week. For me that's soul destroying as it's the
most important week of the year. I'll be counting the days until
Italian Dettori has recorded 56 winners at Royal Ascot, the most
among all active riders.
