Following a decisive victory over Fabricio Werdum, current Strikeforce and DREAM Heavyweight Champion Alistair Overeem avenged his 2006 loss to "Vai Cavalo" in the second half of opening bouts of the Strikeforce Heavyweight Grand Prix Tournament.
Now "The Demolition Man" will look to continue his dominance as he faces Antonio Silva, who is coming off a crushing victory of Fedor Emelianenko.
Meanwhile in the UFC, top level striker Junior Dos Santos clinched the No. 1 contender position over Shane Carwin as he put on a boxing clinic, tearing through Carwin on his way to a unanimous decision victory when his original opponent Brock Lesnar pulled out due to illness.
All the while, Josh Barnett scored a submission victory over Brett Rogers on his way to a semifinal matchup against Sergei Kharitonov and the UFC announced a heavyweight collision in Rio between Brendan Schaub and Antonio Rodrigo Nogueira.
