Yanworth could have his prep run at Wincanton ahead of the Stan James Champion Hurdle after a minor setback forced him to miss his scheduled race at Sandown.A slight pulled muscle forced trainer Alan King to ditch plans to run the JP McManus-owned gelding in the Contenders Hurdle on Saturday.However, King reports the Christmas Hurdle winner much better after having had a few easy days and, as long as the ground is suitable, Yanworth could be seen in the Betway Kingwell Hurdle at Wincanton on February 18."Yanworth is fine. He trotted (on Saturday morning) and he will be back cantering on Tuesday," said the Barbury Castle handler."He slightly pulled a muscle in behind and the only way to get that right is give them an easy few days."I would think he will probably go to Wincanton for the Kingwell. I'd like to get another run if I can."
