Brock Lesnar has pulled out of his cage battle with Junior dos Santos in June due to his ongoing health problems. The fighter was scheduled to fight at the UFC 131 event in June but his illness has left him too sick to train for the fight. Lesnar told TMZ.com that he may go under the knife and endure "life changing surgery" so that he can put his health problems behind him. It was reported that Lesnar suffers from the digestive disease, diverticulitis, and that he currently seeks treatment at the famous Mayo Clinic in Minnesota. In 2009 Lesnar was hospitalised due to his medical condition and had to reschedule his fight with Shane Carwin, who will now fight Junior dos Santos in June. A statement was released on Thursday in which Lesnar put his fan's minds at rest. He said, "I'm not retiring... I love this sport."
