Speaking to TMZ.COM, Dana White said that Brock Lesnar will be requiring major surgery and the company is trying to get him transferred to the Mayo Clinic, a non-profit organization and internationally renowned group medical practice headquartered in Rochester, MN.

The UFC President told TMZ that Lesnar is sick with "some sort of intestinal disorder" however the website suggested that considering the tone in White's voice it sounded a lot more serious than he suggested.

Rumors were spreading around that Lesnar was suffering from mono however White shot down that rumor although he wasn't specific and also added that the disease is not HIV or cancer either.

"There's a possibility Lesnar will never fight again," White said.
