Roy Jones Jnr - the legendary four-weight world champion who was widely regarded as the best pound-for-pound boxer in the 1990s - knocked out a fan in a special US$100,000 challenge on Sunday.
Jones, who has won 62 of his 71 professional fights, headlined a card where fans had the opportunity to fight the 1988 Olympic silver medallist - if they won they would take home a cash prize of $100,000.
Vyron Phillips, a 33-year-old MMA fighter with an amateur boxing background, was voted for by fans ahead of 1500 applicants to step into the ring with Jones - but he was unsurprisingly out of his depth and the referee stopped the bout in the second round.
The fight was part of a multi-sport pay-per-view event held by urshow.tv at the Celebrity Theatre in Phoenix, Arizona, with wrestling stars Kurt Angle and Rey Mysterio going head-to-head on the same bill.
Many fans on social media expressed their distaste at seeing a future Hall of Fame inductee, who dazzled the world with his athleticism and boxing skill in the 1990s and early 2000s, fight in the event, but he would not confirm whether he plans to retire.
