Denis Grachev

On March 30, 2013, Grachev added another big name to his boxing resume when he fought Zsolt Erdei in a controversial 10-round fight and defeated him via split decision.

On April 27, 2012, Grachev took on then-reigning NABF light heavyweight champion Ismayl Sillakh. At the time, Sillakh was a consensus top-10 ranked light heavyweight and was going into the bout as a heavy 11 to 1 odds favorite over Grachev. After being knocked down in the third round by Sillakh, as well as losing most rounds on the judges' scorecards, Grachev rallied an upset of the year TKO victory in the 8th round; also becoming the new NABF light heavyweight champion

Denis Grachev put his NABF light heavyweight title against former IBF super middleweight world champion Lucian Bute on November 3, 2012. The bout took place in Bute's hometown. Despite a tough, solid effort over 12 rounds, Grachev lost by unanimous decision. Though some believed that Grachev won the majority of the rounds (and therefore the fight) with his sheer aggression and the fact that he landed more punches, most analysts and ringside observers agreed and believed that Bute had the upper hand throughout the bout, as he out-boxed Grachev throughout a majority of the rounds of the fight and managed to land the harder punches of both of the fighters.

On July 4, 2011, Grachev went on to capture his first major championship in boxing when he defeated Eddie Caminero with a third round TKO and becoming the WBC Continental Americas light heavyweight champion.

On December 11, 2009 (in a 6-round fight), Grachev fought to a controversial majority draw against Ernesto Castaneda in a fight where he was the effective aggressor, more ring-general, landed more punches and the harder punches in a majority of the rounds, and the fact that almost every ringside observer thought that Grachev had done enough to win. One judge scored it in his favour, with the other to judges scoring the fight even.

After moving to the United States in 2006, Grachev competed in his first kickboxing bout under Muay Thai rules against kickboxing legend Manson Gibson on July 7, 2007. The bout was for International Kickboxing Federation's Muay Thai light cruiserweight world championship. Grachev went on to win the world title with a third round TKO over Gibson after Gibson's corner threw in the towel from too much punishment.

On November 29, 2007, Grachev took on WBC Muaythai light heavyweight world champion Joe Schilling — who is currently renowned for being a sparring partner of mixed martial arts world champion Nick Diaz. Grachev defeated Schilling with a 47-second knockout in the first round after Grachev delivered a spinning heel kick to the body, as Schilling was unable to beat the referee's 10-count. In result, Grachev won IKKC's vacant U.S. super middleweight national championship.

Denis Grachev made the transition to boxing in 2007 when he faced Rosendo Rubalcaba on June 24 — the professional debut for both combatants. Grachev won his professional debut with a second round knockout after knocking down Rubalcaba a total of four times the entire bout.

In 2006, Grachev moved to San Diego, California, United States with Evgeny Khil — long-time friend and fellow kickboxer — after appointing Mark Dion of City Boxing as his manager. Grachev would represent City Boxing's professional fight team, as well as being the gym's kickboxing instructor. Although competing mostly under low kick/international and full contact rules, Grachev competed under Muay Thai rules while in the United States. When Grachev first moved into the United States, he had no understanding of English at all and was enrolled in English classes at San Diego City College by his manager Mark Dion. At this stage of Grachev's migration into the United States, he had been dabbling in mixed martial arts and boxing — his manager Mark Dion had plans of moving Grachev's career away from kickboxing since there was little money in the sport. Due to the lack of popularity of kickboxing in the United States, Denis Grachev eventually made the full-time commitment to boxing in 2011 and is primarily trained by former IBF minimumweight world champion Manny Melchor. Grachev states he has always enjoyed boxing, though resorted to kickboxing while growing up in Russia because there weren't any good boxing gyms in Chaykovsky.

During his professional career in Russia, Grachev competed most of his bouts in World BARS Kickboxing Federation. On September 13, 2006, he won WBKF's vacant Commonwealth of Independent States -81 kg championship under international/low kick rules when he defeated Denis Goncharenko of Belarus.

As an amateur in kickboxing, Grachev achieved a record of 123-18, with 40 of his wins coming by way of (T)KO. In the 2004 WKA/IAKSA Amateur World Championships in Basel, Switzerland — the first joint federation world championship — Grachev won the bronze medal under low kick/international rules. The following year in WAKO's Amateur World Championships in Szeged, Hungary, Grachev won the gold medal under full contact rules, also earning the classification of International Master of Sport in kickboxing.
