Medina Spirit is trainer Bob Baffert’s fifth horse to fail a drug test in a year. He denied any wrongdoing. Medina Spirit was tested again to confirm the accuracy of the first test.

Kentucky Derby winner Medina Spirit has tested positive for a banned race-day drug, its trainer announced.

The horse, Medina Spirit, could be disqualified and lose the title if further testing confirms the results.

Bob Baffert, a Hall of Fame trainer, announced that 2021 Kentucky Derby winner Medina Spirit had failed a post-race drug test, describing the result as a "complete injustice."

The New York Times reports that Justify, the horse that won all three major races in 2018, failed a drug test a month before the Kentucky Derby.

It's the first equine fatality since March 31.

Kentucky Derby winner Country House will not race in the Preakness Stakes due to health concerns, according to its trainer.

Flavien Prat rode Country House with 65-1 odds in the 145th Kentucky Derby.

Flavien Prat speaks out about his victory with Country House after the first-place winner, Maximum Security, was disqualified.

Country House's jockey objected Maximum Security's win, claiming that the horse "veered out of his path in the final turn."

Justify charged out of the gate and never gave up the lead, powering his way to victory at the Belmont Stakes to become just the 13th horse to win the Triple Crown.

The injured jockey suffered a clavicle fracture.

There will be no Triple Crown winner this year.

The horse - the pre-race favorite - remains undefeated.

Nyquist will make his run for the roses at Churchill Downs in the 142nd Kentucky Derby on Saturday.
