White told MMAjunkie that Holloway will be on the sidelines until they figure out exactly what happened with him. The promotion pulled Holloway from a title defense this Saturday at UFC 226 vs. Brian Ortega due to concussion-like symptoms.

“It’s a weird situation,” White said. “I was just talking to Jeff Novitzky in the back, and there’s a couple of different – some people think it’s concussion-related, some people think it’s weight-cutting related. They haven’t really got down to the bottom of what it is, but according to him, he feels fine. But obviously he’s not fine. So we’re going to continue to try to figure out what’s wrong with Max Holloway.

“In the meantime, there’s no way this guy’s going to fight anytime soon.”

Twice this week Holloway has been forced to go to a Las Vegas hospital. His interview on “UFC Tonight” also caused concern with those watching.

“We’re running him through every test there is,” White said. “He needs to go to like the Mayo Clinic or one of these places and do a full – yes, we will take care of Max Holloway. He’ll go through every type of testing there is until we figure out what’s wrong with him.”
