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.
