There will be no Triple Crown winner this year.

Controversial Kentucky Derby winner Country House will not be running in the May 18 Preakness Stakes after developing a cough, trainer Bill Mott told the Daily Racing Form on Tuesday.

“He developed a little bit of a cough this morning,” Mott told the paper by telephone. “His appetite is good. He doesn’t have a fever. But he’s coughing. We drew blood. He’s acting like he’s going to get sick. He’s off the training list, and if he’s off the training list, he’s off the Preakness list.

“It’s probably a little viral thing. Hopefully it doesn’t develop into anything serious. Usually when something like this happens, a horse misses a couple weeks of training. He’s not seriously sick right now. But he’s showing indications that something is going on.”

Country House was the beneficiary of Maximum Security’s disqualification at Churchill Downs after stewards ruled he illegally cut off challengers. Maximum Security’s owner, Gary West, told the “Today” show on Monday that his horse would not race at the Preakness Stakes with the Triple Crown no longer in play.

Country House developed the illness after winning the Derby and has yet to leave Churchill Downs, Mott said.

The run of Triple Crown bad luck started before the Derby when favorite Omaha Beach was scratched with a lung problem days before the race.
