A lightweight contest between Phillipe Nover and Sam Stout has been cancelled Wednesday evening for UFC Fight Night 19 in Oklahoma City, Okla.

Nover, 25, reportedly had a seizure backstage while prepping for the bout, a UFC official and other multiple sources have told Sherdog.com.

“Nover had a seizure in the locker room. He is ok,” UFC President Dana White posted on his Twitter account Wednesday afternoon.

The Oklahoma State Athletic Commission is said to have officially called off the bout.

Nover, a runner-up on “The Ultimate Fighter 8,” was taken to a nearby hospital, said the official.

Sherdog.com has not been able to reach Nover or his representatives for confirmation.
