However, rumors are circulating that suggest Lesnar's career might still be in jeopardy.
According to themmacorner.com, sources close to Lesnar's camp have reported that the former UFC heavyweight champion has been told by more than one doctor that continuing to compete would be inadvisable, considering the stress that training and fighting puts on the human body.
Whether or not Lesnar will actually heed the warnings of his physicians remains to be seen, but for the time being, it seems he wants to continue to compete.
The question is whether or not continuing to train and fight will again aggravate his disease.
Lesnar was first diagnosed with diverticulitis in 2009, when he was forced to withdraw from a match with Shane Carwin at UFC 106.
After taking some time to recover from the illness, Lesnar made a successful return at UFC 116, submitting Shane Carwin in the second round with an arm-triangle choke.
The former WWE superstar then went on to defend his championship against Cain Velasquez at UFC 121. The fight did not go Lesnar's way, with Velasquez coming out strong and winning by first-round TKO.
After losing the belt, Lesnar looked to reclaim it by coaching a season of The Ultimate Fighter opposite Junior dos Santos. After coaching, the two heavyweights were meant to meet in a No.1 contender's matchup.
Lesnar's diverticulitis served as a bump in the road back to the title, taking him out of commission before he got the chance to fight dos Santos.
The second bout with his disease proved to more serious than the first and Lesnar had to have a 12-inch piece of his colon removed and repaired.
It's clear that Lesnar wants to continue fighting and even become a world champion again, but will he actually continue to fight, considering the advice given from his doctors?
