SALT LAKE CITY (AP) — Former Republican presidential candidate Mitt Romney and five-time heavyweight boxing champion Evander Holyfield are set to square off at a charity fight night event in Salt Lake City.

In full protective gear, Romney and Holyfield will spar in the boxing ring Friday night for a lighthearted fight before the night's three fights by professional boxers.

The black-tie event is raising money for the Utah-based organization CharityVision, which helps doctors in developing countries operate on people to restore their vision.

Romney's son Josh Romney, who lives in Utah, serves as a volunteer president for CharityVision.

Corporate sponsorships for the event range from $25,000 to $250,000. Organizers say the event is expected to raise $1 million.
