At the age of 18 and while he was still attending his course at Loughborough University, Nick joined a local martial arts club, the
Hung Kuen Shaolin Kung Fu Club. Being a diligent martial arts practitioner, he soon won the
UK National Kung Fu Open Weight Championship. However, Nick was inspired to take up MMA after watching ''
UFC's Ultimate Knockouts'' DVD, and started searching out the best places and coaches to train with up and down the United Kingdom. For a while, Nick served as a sparring partner for some of the UK's best MMA fighters, and most notably in 2008 he was invited to be the sparring partner of
Michael Bisping during his preparation for his upcoming fight against
Chris Leben at
UFC 89 in Birmingham, UK. After two years of training in MMA and helping others too, Osipczak also began competing in the UK, and went undefeated in all his amateur and semi-professional bouts. In March 2008, Nick also made his professional MMA fighting debut and offered his opponent a “winner-takes-all” bet, which his opponent initially refused. When they eventually fought, Nick won the fight in only 76 seconds, and displayed what would later be known as his “helicopter punch”. The opponent for his third professional bout accepted a “winner-takes-all” deal, and Osipczak won by rear naked choke, taking his record to 3–0. All of Nick's professional fights had been won in under two minutes and relatively easily, which helped to catch the attention of the casting crew when he auditioned for
The Ultimate Fighter: United States vs. United Kingdom, while
UFC's president,
Dana White, was also present. ===
The Ultimate Fighter=== Osipczak also appeared on
The Ultimate Fighter: United States vs. United Kingdom. He first defeated the British MMA professional fighter
Tommy Maguire by knock out in the first round in an elimination match, earning him the trip to
Las Vegas, Nevada, to compete on the show. Osipczak then had his second fight against
Team United States fighter
Mark Miller. Osipczak defeated Miller via a second-round knockout from a powerful head kick, which was voted in the top 15 all-time TUF knock-outs. However, Nick lost his semi-final fight against
DaMarques Johnson, although
Dana White called the fight one of the best fights in
TUF history.
Ultimate Fighting Championship Osipczak made his
Ultimate Fighting Championship debut at
The Ultimate Finale 9 on 20 June 2009, and he fought his former
TUF castmate and
Team United States fighter,
Frank Lester in
Las Vegas,
Nevada. Osipczak defeated Lester by using a rear naked choke. His overall performance in that night helped him renew his contract for three more fights for the
UFC. Osipczak faced
TUF 7 alumnus,
Matthew Riddle on 14 November 2009 at
UFC 105 in Manchester, UK. In a pre-fight interview, Osipczak stated that Riddle has no serious finishing ability and is most often than not a fighter who likes to "grind out a decision". Riddle countered the statement by saying that he considers Osipczak without considerable experience against wrestlers, which he attributed to the wider lack of wrestling training of UK MMA fighters. However, Osipczak dominated throughout the fight by showing a superior standing up and striking as well as grappling game. When Osipczak at some point fully mounted Riddle in the final round, he started a vicious ground and pound barrage of punches and elbow strikes which made the referee
Mark Goddard to end the fight at 3:53 in the final round.
UFC commentator
Joe Rogan mentioned that this was a "huge performance by Osipczak". Osipczak then fought
Rick Story at
UFC 112 in
Abu Dhabi,
United Arab Emirates. Osipczak lost the fight via a controversial split decision. According to MMA Fanhouse who were doing a live play-by-play from the event, "Most on press row didn't agree with the decision. Looked like Osipczak won Rounds 2 and 3." Osipczak was defeated by
Greg Soto at
UFC 118 in
Boston,
Massachusetts, after the fight went all three rounds and the judges awarded the fight to his opponent via unanimous decision. Osipczak was upset by
Duane Ludwig at
UFC 122 in
Oberhausen, Germany, via a split decision, which again sparked some controversy.
Students In 2011, Osipczak started running his own MMA academy in South London, the
New Wave Academy, which immediately became one of the most up and coming MMA academies in London and he became a mentor to many London-based professional MMA fighters. Although he officially left his academy to two of his students in 2012, as he was aiming at having more time to further develop his martial arts knowledge and skills, he currently continues teaching some of the top British professional MMA fighters at the premises of ''
Eddie Kone's Academy of Jiu Jitsu''. In early 2014, Nick announced that he is ready to return to MMA competitions, feeling “reborn”. ==Return to Mixed Martial Arts competition==
