Overpowered, the smart juvenile from Paul Cole’s Whatcombe stables, near Wantage, was killed in an accident over the weekend.

The son of Choisir, who broke his duck at Ripon before bolting up in a nursery at the Newmarket July meeting, was entered in next month’s Champagne Stakes at Doncaster.

“Unfortunately we lost one of our best two-year-olds, Overpowered, in a freak box accident on Saturday,” reported Cole’s website.

“It's a sad loss to all concerned, the lads, owners (Jill Haines and Jared Sullivan) and the yard.”
