The 2010 M-1 Challenge season was the third season of mixed martial arts (MMA) fighting presented by the M-1 Global promotion.  The season started on February 5 and will conclude with the M-1 Challenge XXII event on December 10.  Unlike in previous years where competition was arranged entirely around country-based teams, the 2010 competition had a greater focus on individual achievement.  Rather than the sixteen "country" teams of the 2009 competition, the 2010 M-1 Challenge featured eight teams representing four "continents" – Europe, Russia, Americas and Asia – with each continent having two teams.  Four of the teams are drawn from the M-1 Selection events whilst the other four are selected from, and featured, veteran MMA fighters.  Events held near the end of the year featured bouts to crown inaugural M-1 Global Champions in each of the five weight divisions.

Nicknamed the "Motor City Cobra", and more famously "The Hitman", Hearns' tall and slender build allowed him to move up over fifty pounds in his career and become the first boxer in history to win world titles in four weight divisions: welterweight, light middleweight, middleweight, and light heavyweight.
