Hall of Fame jockey Julie Krone was taken to Arcadia Methodist Hospital complaining of back pain after she fell from her mount, Sublet, at the start of the 5th race at Santa Anita Saturday. She's the latest rider to be injured during a string of mishaps at the Arcadia, Calif. track in recent weeks. Krone's husband, Jay Hovdey, reported that x-rays were negative, but that she's extremely sore and will be taking a couple days off. She may be ready to ride again on Wednesday.Sublet, a 4-year-old gelding trained by Ian Jory, stumbled badly at the break for the 6 1/2-furlong downhill turf race, tossing Krone over his head and hard to the ground.The 39-year-old jockey is just the latest injured in racing-related accidents over the past two weeks at the Southern California oval. Omar Berrio, Joe Steiner, Felipe Martinez, Victor Espinoza and Laffit Pincay Jr. were all involved in spills recently and missed time as a result. The most severe injuries left Joe Steiner with a broken foot and orbital socket of his right eye and Pincay with two fractures to one of the vertebrae in his neck, threatening both riders' careers.Krone, who turns 40 in July, is the only female member of the Hall of Fame, having been inducted in 2000. She is also the only female rider to have every won a classic race, taking the 1993 Belmont Stakes (gr. I) aboard Colonial Affair. After retiring in April of 1999, she returned to the saddle with tremendous success in late 2002 and currently ranks fifth in the jockey standings at the current Santa Antia meeting with 33 wins.
