(CNN)Call him a glutton for punishment, but Mitt Romney is looking for another drubbing.
Romney's next fight: Boxing Evander Holyfield
But instead of another campaign, Romney is jumping into the ring -- an actual boxing ring -- with ex-heavyweight champion Evander Holyfield, a Romney aide confirmed on Monday.
"It will either be a very short fight, or I will be knocked unconscious," Romney told the Salt Lake Tribune.
Romney, 68, will suit up and face the 52-year-old retired boxer for a charity event in Salt Lake City on May 15.
But don't expect a knockout, Romney said the pair will "spar around a little bit," assuring that "it won't be much of a fight."
Proceeds of the event will go to Charity Vision, a charity group founded by a physician and former Mormon missionary aimed at bringing medical care -- mostly eye surgeries -- to impoverished areas of the world.
Romney, a Mormon, has become involved in the organization's charity work, according to the Tribune. Romney ruled out a third presidential bid earlier this year.
