The in-form Irishman was all set to partner the unbeaten six-year-old for Donald McCain on March 15 — but found himself in hot water with the stewards at Doncaster following his ride on the stable’s Cool Mission, runner-up to Beshabar in the three-mile beginners’ chase.
His suspension will be effective from March 9-15 inclusive. Five days of the ban was for marking the horse, with two days for using his whip with excessive frequency.
Stipendiary steward Robert Earnshaw said: “He has been suspended for using his whip on Cool Mission. The veterinary officer found that the horse had minor weals, for which he was suspended five days.
“He was also suspended two days for using his whip with excessive frequency.”
Maguire said: “It’s very frustrating for me because it’s the first day of Cheltenham and I’m due to ride Peddlers Cross.
“I’m obviously going to have to appeal and see what happens.
“I gave the horse a strong ride. It’s the marking that’s caused the problem.
“Once you mark a horse there’s no comeback from that, but something has to be done about that rule.
“We are all interested in the welfare of horses but there has to be some leeway for the jockeys.”
McCain said: “The stewards in the north have been chasing us all year and now they’ve got us.
“This has happened an awful lot with my horses in the north and it’s becoming a joke.
“Jason is devastated as they’ve cost him a Champion Hurdle ride.’’
