LOUISVILLE, Ky. (WDRB) -- Kentucky Derby winner Nyquist is out of the Belmont Stakes.

According to a news release from the Pimlico Race Course, the horse has an elevated white blood cell count.

"Nyquist's blood work came back this morning and there's a slightly elevated white count," said Jack Sisterton, assistant trainer of Nyquist, in a YouTube video posted this morning. "We took his temperature again and that was slightly elevated. So I spoke to Doug [trainer Doug O'Neill], and Doug wants to do what's best for Nyquist and get him back 100 percent health-wise here at Pimlico, and fly him back to California. We’re not sure exactly the day we’ll do that, but Nyquist will tell us when he's ready." 

Nyquist was supposed to ship to New York yesterday, but that didn't happen because the horse was running a fever of 102. O'Neill tweeted that Nyquist's temperature returned to normal after the horse got treatment for it, but they were waiting for blood tests.

Nyquist finished third in the Preakness Stakes.
