Middleweight contender Matt Korobov has ended his boxing career, according to recent statements from the 40-year-old athlete.

Korobov (28-4-1, 14 KOs) has not fought since 2020. He lost two fights in a row, both due to physical injuries. 

Against Chris Eubank Jr. in December of 2019, the fight was stopped after Korobov injured his left shoulder and was unable to continue, with Eubank deemed a TKO winner after only two rounds.

A year later, Korobov was once again unable to continue after injuring his ankle during the fourth round of his fight with Ronald Ellis.

At that point, Korobov was 0-3-1 in his last four outings.

Given his age and his body breaking down from a long career in the amateur and pro ranks, Korobov decided to walk away to become a full-time trainer.

“I am satisfied with my career and then also I'm not,” said Korobov to Tass. “Everything could have turned out better for objective and subjective reasons. There were many external factors that were not in my favor. But as a whole I am satisfied, I left a certain mark.

“I have always strived for the top, now I am striving for it already as a coach. I will try to realize my potential as a coach. There are several people, including talented children, whom I am now coaching."

Korobov is a two-time amateur world champion, winner of the European Championship, winner of the World Cup, four-time amateur champion in Russia, and took part in the 2008 Olympic Games in Beijing.

At the 2006 European Championships, Korobov defeated Ukrainian's Oleksandr Usyk, who unified the entire cruiserweight division and is now the unified heavyweight champion.

Korobov also held amateur wins over Yordanis Despaigne, Sergiy Derevyanchenko, Carlos Gongora Alfonso Blanco and Gaydarbek_Gaydarbekov. Korobov's amateur record was 300-12.
