Photos: Gennady Golovkin, Kell Brook in Tense Face To Face!

Matchroom Boxing and K2 Promotions are delighted to announce that Unified Middleweight World Champion Gennady “GGG” Golovkin will defend his WBA, WBC, IBF and IBO Middleweight World titles against IBF Welterweight champion Kell Brook at The O2 in London on September 10, live on Sky Sports Box Office and Live on HBO World Championship Boxing®.

The two unbeaten stars collide in London with the US-based Kazakh KO king Golovkin stepping into the ring as a defending champion for the 16th time and looking to keep up his incredible knockout percentage – with 32 of his previous 35 fights ending early, including all of his World title outings and is ready to add to that run in his first fight in the UK.

 “I’m very excited to be fighting in front of the great British boxing fans and promise another ‘Big Drama Show’ against undefeated Kell Brook,” said Golovkin. “I give him much respect for taking this fight.”

Most recently Golovkin has sold out famed venues in the United States, Madison Square Garden in New York City and The Fabulous Forum in Los Angeles.

On October 17, 2015 Golovkin knocked out IBF Middleweight World Champion David Lemieux at Madison Square Garden in front of 20,548 fans. Most recently, Golovkin stopped Undefeated Mandatory Challenger Dominic Wade on April 23, 2016 in the second round at the sold-out Fabulous Forum before a crowd of 16,353.

‘GGG’ has beaten two British fighters already in his career in Matthew Macklin and Martin Murray, but Brook will be out to take his mantel as the World’s most feared fighter. ‘The Special One’ moves up from Welterweight where he holds the IBF title that he ripped from Shawn Porter in August 2014, defending it three times since then with KO wins in all to take his own impressive unbeaten record to 36-0 with 25 wins inside the distance.

Brook – who will retain his status as IBF Welterweight champion – has been hunting a major fight since landing the World title, and the 30-year-old believes he has the tools to defeat Golovkin and become boxing’s biggest star.

“This is the fight and the moment I have been waiting for for some time,” said Brook. “We've tried and tried to lure the best to come and fight me and now we've got the best of the best – the number one pound for pound fighter in the world is coming to the UK."

“When this fight got offered to me I accepted within minutes and I can't wait. Everyone knows I'm a huge welterweight and I know I will carry my speed and accuracy and even more power through the weights. This is the ultimate fight, one of the biggest international fights the country has seen in many years - you have seen some huge names run from GGG but I'm running to him. I'm a Special fighter and I will show the World on September 10.”
