After taking a brutal two round beating from Antonio Silva, Fedor Emelianenko seemed to announce his retirement immediately after the fight. According to his translator Fedor said, "maybe it's time to leave."

He thanked everyone for a beautiful "sporting life".

Emelianenko will retire as the greatest heavyweight fighter in MMA history. He dominated the sport for the better part of a decade in an incredible ten year undefeated streak, mostly in Japan for the legendary Pride organization.

This was his second loss in as many fights. Fabricio Werdum forced him to tap to a triangle choke at 0:69 of the first round. Emelianenko had only lost once in his prior career, way back in December 2000 in RINGS King of Kings tournament.

In his storied career, Fedor beat Antonio Rodrigo Nogueira (2x), Mirko Filopovic, Mark Coleman, Andrei Arlovski and Tim Sylvia.

Fedor had been favored to win the Strikeforce heavyweight grand prix tournament. Antonio Silva will face the winner of Fabricio Werdum vs Alistair Overeem. Tonight's other winner Sergei Kharitonov beat former UFC champ Andrei Arlvoski and will await the winner of Josh Barnett vs Brett Rogers.

Arlovski may also face retirement after losing his fourth straight fight -- all of them since leaving the UFC.
