YOUMZAIN RULED OUT OF KING GEORGE
YOUMZAIN will be an absentee from the King George VI And Queen Elizabeth Stakes on Saturday week after sustaining a minor setback.
The six-year-old was this morning found to have a swollen near-fore joint that although superficial is enough to scupper his chance of lining-up for Ascot's mid-summer feature.
Mick said: "The horse isn't lame but there's swelling round the joint and we can't take any chances. X-rays taken on the leg showed nothing for us to get worried about, and he'll hopefully be back later in the year."
Youmzain finished third in last year's King George and most recently occupied the same placing in the Grand Prix de Saint-Cloud. Ironically he had worked encouragingly in a visor as recently as Tuesday.
