M-1 Global closed out a busy 2015 with the 63rd edition of the Challenge series, this time with three title fights atop the card.
In the main event, former light-heavyweight champion Viktor Nemkov recaptured his title with a majority decision victory against then-reigning champ Stephan Puetz. Similar to their first fight nearly two years ago, this was a competitive contest that lasted the entire five rounds.
The co-main event saw middleweight champion Ramazan Emeev defend his title against UFC veteran Luigi Fioravanti. Emeev dominated the entire contest and was eventually awarded the victory when his Italian-American foe was unable to answer the bell for the final round.
