Brock Lesnar was released from hospital in Bismarck North Dakota and will recover from a bacterial infection at his home.
Lesnar's coach Greg Nelson, head instructor at the Minnesota Mixed Martial Arts Academy told the Canadian Press that Lesnar's prognosis is looking more positive at this point.
"He's at home now, much better than he was," Nelson explained to CP on Wednesday. "He was in a lot of pain, obviously dealing with a lot of different medicines dealing not only the pain but also for the infection.
"Definitely, he's feeling better. He's at home, that's where he wants to be."
Nelson also admitted that there is still a possibility, but no guarantee, that Lesnar may require surgery down the road.
"We'll see and if does, he'll obviously go to a good place," Nelson told CP, "because obviously his goal is to get back and get back in the cage."
Lesnar's friend and chiropractor Larry Novotny told the Associated Press late Thursday that Lesnar was home and would not be making any decisions about his career until his health improved.
Novotny's claim was backed up by UFC president Dana White on his twitter account.
"Leaving Bismarck, N.D., right now. Brock had minor surgery and is feeling better," White wrote. "Not 100 per cent sure he is out of the woods but feeling better."
While Lesnar and the UFC have not commented on the specifics of his infection or surgery, WCCO-TV in Minneapolis is reporting that Lesnar had a severe case of diverticulitis, which is a common digestive disease that causes small pouches to form in the digestive system.
Surgery for the condition could become necessary when there is concern that the infection could spread and cause a potentially fatal inflammation.
Lesnar originally was supposed to fight Shane Carwin on November 21 for the title, but that fight was cancelled at the time because Lesnar had mono. The UFC were planning on staging the fight at UFC 108 in January, but with Lesnar's illness the fight has obviously been cancelled.
White told the Associated Press on Monday that Lesnar wanted to thank his fans for their support.
