Enzo Maccarinelli beat Roy Jones Jr with a devastating fourth-round knockout at the VTB Arena in Moscow.
The 35-year-old got the better of the opening two rounds before the 46-year-old Jones Jr, now a Russian citizen, rallied to get back into the non-title cruiserweight contest in the third.
But in the fourth, Maccarinelli dropped Jones Jr with a big uppercut, and although he beat the count to resume the fight, the Welshman pinned Jones Jr against the ropes and stunned him with another uppercut before a right hook sent him face first to the canvas and referee Ingo Barrabas waved off the fight.
