One day after pre-entries for the Oct. 29 Breeders' Cup World Thoroughbred Championships were announced, there were two defections Thursday.Dressed to Kill, a maiden pre-entered in the Alberto VO5 Breeders' Cup Juvenile Fillies (gr. I), has been withdrawn from the 1 1/16-mile race after sustaining a fracture of the left front pastern bone."On Tuesday, she had a routine gallop and then took a funny step," trainer George Weaver explained. "When she got back to the barn she was sore and then we discovered a fracture in her front left. It was pretty ambitious to enter her in there since she is a maiden, but we thought she had run well in all her races. But these things happen and you just have to roll with the punches and keep going."Weaver said the prognosis is good for the filly to eventually resume racing, pending a satisfactory recovery from surgery. Owned by Sugartown Stable, the daughter of Formal Gold was fifth in her career debut, third in the restricted P. G. Johnson Stakes, and second in the Salem County in three career starts, all on grass.The other defection of a pre-entered horse was of Sharp Attack, who was first on the also-eligible list in the oversubscribed Bessemer Trust Breeders' Cup Juvenile (gr. I). Trained by D Wayne Lukas for William A. Marquard and Overbrook Farm, the son of Storm Cat had two victories from five career starts.The defection of Sharp Attack moves Bear Stables' Bear Character to first on the also-eligible list, and he would move into the main body of the field if there are any scratches before final entries are taken at 10 a.mn.
