After being declared the winner of the Kentucky Derby by disqualification, Country House will not run in the Preakness because of illness, ending any chance of a Triple Crown this year.

Trainer Bill Mott said Tuesday the long shot winner of horse racing's biggest event was no longer being considered to run in the second jewel of the Triple Crown after it looked like Country House was getting sick. After the horse started coughing, which Mott called unusual, blood work showed he was harboring some sort of virus.

"Hopefully just rest and a little time is going to be what the doctor ordered," Mott told The Associated Press. "Other than that, he doesn't actually act sick. He's kind of a big, tough horse, but there's signs that things are not going in the right direction with him."

Country House, whose co-owners are from Thomasville, was elevated to the winner's circle at the Kentucky Derby in sloppy conditions Saturday after Maximum Security was disqualified for impeding other horses. His absence at the Preakness means there won't be a third Triple Crown winner in five years. Bob Baffert-trained Justify and American Pharoah have each won it since 2015.
