Kentucky Derby winner Barbaro's surgeon saw encouraging signs Tuesday that the colt's hind legs are healing, according to an update issued Wednesday by the veterinary hospital where Barbaro is being treated for fractures in his right hind leg and laminitis in his left hind.
Dr. Dean Richardson, chief of surgery at the University of Pennsylvania's New Bolton Center equine hospital, changed the cast on Barbaro's right hind leg late Tuesday afternoon with the colt under general anesthesia.
