Former world champion DeMarcus Corley, who once shared the ring with Floyd Mayweather, lost for the 30th time in his career on Saturday night.
Fighting in Krasnodar, Russia against Aik Shakhnazaryan, Corley was comprehensively beaten over the ten round distance at Olimp.
Scores were wide on the cards 100-90, 99-92 and 98-92 as the home fighter improved to 22-2, 11 KOs.
Corley is scheduled to be back in the ring as early as next month in a rematch opposite another veteran ex-world ruler in Vivian Harris, having beaten the one-time super-lightweight champion in 2017.
Furthermore, the 44 year-old is then pencilled in to fight at Garfield Park on August 11.
At this rate, Corley could end up hitting a century of fights before his retirement having already participated in 82 bouts.
