Emelianenko floored Rizzo with a right hand then followed him to the ground for more and to stop the fight.

Emelianenko now with three straight back-back wins after losing to Fabricio Werdum, Antonio Silva and Dan Henderson in Strikeforce.

Before he met the three former MMA stars, he was an unstoppable force, racking up 31 wins, one loss and one no contest.

Following Fedor Emelianenko’s 84-second demolition of Pedro Rizzo, none other than Russian President Vladimir Putin stepped into the St. Petersburg ring and personally bestowed praise upon 'The Last Emperor' for his contribution to and promotion of MMA in Russia.

“I want to congratulate Fedor and thank him from all of us, martial arts fans. It is because of him this sport became so popular in our country,” the Russian premier said.

Before this bout, Emelianenko told Russian television this fight would be his last, but he did not talk about retirement in his post-bout interview.

It remains to be seen if 'The Last Emperor' is truly done with MMA.
