Kell Brook and Gennady Golovkin battled in an unexpectedly fierce contest that ended with the challenger's trainer chucking in the towel and extending GGG's record to 36 wins and 33 KOs.
Brook was rocked in the first round by Golovkin's sheer power, but he managed to mount a comeback late in the round and probably took the second round too.
The Sheffield-born fighter looked like he might have shaken his Kazakh counterpart at various times in the fight, but the undefeated WBC, IBF, and IBO middleweight champion refused to give Brook the credit he really deserved.

“Kell is a huge fighter, a very good fighter … sorry, but he’s not a middleweight," Golovkin insisted straight after the fight. "I respect him, he is good… but not so strong.”
When asked if Brook hurt him: “No, he just touched. So many punches, but I don’t feel them. I respect Kell, he’s a warrior, and his corner, for his career, for his family, was correct. It was game over! I want a unification fight – I want to fight Billie Joe Saunders. He has the WBO belt.”
Brook insisted he would fight GGG again in his post-fight interview, but Special K is now more than likely going to step down a weight division and look for the winner of Saul 'Canelo' Alvarez and Liam Smith.
However, the 30-year-old can hold his head high after insisting he would take the fight to the most feared knockout puncher in the world, and he did just that.
As for GGG, he has his sights set on a middleweight unification fight with Billy Joe Saunders, who holds the WBO belt.
