Kentucky Derby winner Animal Kingdom will have surgery for a fracture in his left hock, his owners announced Wednesday.
The 3-year-old old chestnut colt was out of training after a small fissure was found in the hock two weeks ago. X-rays were retaken this week and a larger fracture was found in the same area. Surgeons at New Bolton Center near Philadelphia will place a screw in the hock to compress the fracture.
Animal Kingdom is expected to return to training in time for the Dubai World Cup in March 2012.
