-- Two horses died and a jockey was injured at Pimlico Race Course during the first few races of a rainy Preakness Saturday in Baltimore.
Later, racehorse Pramedya fractured her left cannon bone while racing on a turf course, according to Sinatra, and Pramedya’s Jockey, Daniel Centeno, fell and suffered a right clavicle fracture. Pramedya, 4, was euthanized on the track, according to The Associated Press.
Homeboykris' owner, Jan Klein, said in a statement to ABC News, "We are all just heartbroken."
"Kris had a small team who loved him and cared about him. His trainer, Fran Campitelli; his caretakers; and of course, me," Klein said. "He loved what he did and we will all miss him. Such a wonderful competitor with a marvelous record.
"We all feel privileged to have been a part of his life," she said.
There will be an autopsy for 9-year-old Homeboykris at the New Bolton veterinary care center in Pennsylvania, Sinatra said.
Pramedya's owners, Roy and Gretchen Jackson, also owned the Kentucky Derby-winning horse Barbaro who shattered bones in his leg at the start of the Preakness in 2006. Barbaro developed laminitis and was euthanized in 2007, according to the AP.
The Jacksons did not immediately respond to a request for comment.
