Despite being bloodied in the opening seconds of the fight, top-ranked heavyweight Fedor Emelianenko did what most predicted he would, scoring a second-round knockout of previously undefeated Brett Rogers on Saturday in the main event of Strikeforce: Fedor vs. Rogers.

In the evening’s co-headliner, Jake Shields was crowned Strikeforce’s middleweight champion with a unanimous decision victory over Jason “Mayhem” Miller.

All 20 fighters who will be in action at tomorrow’s CBS-televised Strikeforce: Fedor vs. Rogers event in Hoffman Estates, Illinois successfully made weight today for their bouts.

Top-ranked heavyweight Fedor Emelianenko tipped the scale at 232 pounds, while his main event opponent, Brett Rogers, came in 32 pounds heavier at 264 pounds.

Strikeforce heavyweight champ Alistair Overeem, who has yet to fight again for the promotion since winning the title in November 2007, returned to MMA action overseas over the weekend, dominating Tony Sylvester at Ultimate Glory 11 in Amsterdam, Netherlands before finishing the fight with a guillotine choke in just 83-seconds. Overeem will fight again this weekend at DREAM 12 against James Thomson before he’s expected to return to Strikeforce to defend the title.
