"A severe heel bulb injury sustained during the warm-up for the Grand Prix in Rotterdam means that recovery will take just a little longer. Of course, we cannot take any risks with our fantastic horse, who has performed amazingly over the past year," Thijssen continued.

"We were almost certain that Cuppie would have loved the grass arena in Aachen, but unfortunately, it was not meant to be," the rider concluded.

Earlier, it was also announced that Gilles Thomas is withdrawing his Ermitage Kalone from participation, as well as André Thieme with his DSP Chakaria.
