Imperial ruled out for season
The 2010 Cheltenham Gold Cup hero was last seen pulling up in the Prestbury Park blue riband after suffering a broken blood vessel, but had been under going a pre-training regime at Mount Top Stud in Ireland.
The 10-year-old was due to return to trainer Nigel Twiston-Davies in the near future but now looks set for an extended holiday after a tear was found in a foreleg tendon following light exercise earlier this week.
