Kazakh boxer Gennady Golovkin will look to defend his WBA, WBC, and IBO middleweight titles when he meets Mexico’s Saul “Canelo” Alvarez in Las Vegas on September 15.
During a weigh-in on September 14, the boxers appeared close to a major physical confrontation before their entourages broke up a minor scuffle.
"I saw he's like a clown. He is showman. He is not true guy," Golovkin, also known as Triple G, said about his opponent.
"I won the weigh-in, and tomorrow I'll win the fight," Alvarez said.
The 36-year-old Golovkin -- with a record of 38 wins, no losses, and one draw with 34 knockouts – weighed in at 72.4 kilograms. He is considered a slight favorite in the fight.
Mexico's 28-year-old Alvarez (49-1-2, 34 knockouts) weighed in at 72.3 kilograms.
Their first fight a year ago ended in a controversial draw when each fighter was favored on the ticket of one judge, while the third judge declared a tie.
Alvarez was temporarily suspended by the Nevada State Athletic Commission in April for testing positive for the banned substance clenbuterol, forcing a postponement of the rematch, which was originally scheduled for May 5.
Alvarez blamed the positive test on contaminated meat.
