In one of the biggest racing shocks in years, Mufhasa has been taken off trainer Stephen McKee and placed with rival trainer Bruce Wallace.
It is understood McKee and senior partnership owner David Archer met at McKee's Ardmore stable on Thursday morning.
Not much more than 30 minutes later a float arrived to remove the Archer horses, including Mufhasa, from the stable.
Yesterday McKee was reluctant to discuss the matter in depth.
"All I want to say is the horse has won 20 races, 10 at group one level. I hope he retires in the same sound condition he left my place in."
