With the Belmont Stakes days away, thoroughbred racing is still reeling from Barbaro's breakdown at the Preakness. This kind of injury can happen at a minor track or before a national TV audience. In fact, it happens nearly twice a day in the U.S. and Canada, according to one expert. (AP Photo/Mike Albans, file)
