Vitaly Dunaystsev has hung up his gloves.
The Russian light-welter told the Tass News Agency that he was retiring aged 27 to take up other roles in the sport.
A bronze medallist at Rio 2016, Dunaystsev, who has also won World and European gold, has a chequered record against former Irish Elite champions Sean McComb, Wayne Kelly and Dean Walsh.
McComb recorded two wins over the Russian stand out in Kharkiv and Dublin’s National Stadium in 2017 but Kelly and Walsh dropped tight points decisions to the former World No.1 in 2016 and 2014.
Dunaystsev won 42 of his 53 bouts in the amateur ranks.
