The rematch is on for boxers Gennady "Triple-G" Golovkin and Saúl "Canelo" Alvarez. After battling to a controversial draw last year, the two fighters will meet again September 15th in a world title bout in Las Vegas. Triple-G will defend his three middleweight titles and looks to remain unbeaten. Alvarez hopes to prove doubters wrong, as most spectators believe he lost the first fight but was gifted a draw. His only career loss was to Floyd Mayweather in 2013.
