I'm gonna say that Fedor gets upset in his first fight...
Fedor Emelianenko (32-2) vs. Antonio Silva (15-2) - Bigfoot by decision
Andrei Arlovski (15-8) vs. Sergei Kharitonov (16-4) - Arlovski nearly gets KOd in the first, but Sergei gets tired by the end of the first and Arlovski by decision
Replacement fight - Shane Del Rosario (10-0) vs. Lavar Johnson (15-3) - Del Rosario by first round TKO or submission
Barnett (26-5) vs Rogers (11-2) - Barnett submission first round
Overeem (34-11-1) vs Werdum (14-4-1) - Overeem by first round TKO
Next up Barnett vs Arlovski - Barnett first round submission
Overeem vs Bigfoot Silva - Overeem first round TKO
Barnett vs Overeem - Overeem gets DQd for either knee to the head of a grounded opponent or biting of headbutting.
Barnett becomes champ...first title defense is Fedor and Fedor KOs Barnett to get the belt back....then Overeem fights Barnett...Overeem wins....Fedor decides he wants to fight Del Rosario....Overeem moves to the UFC....Fedor vacates the title...then Daniel Cormier gets the belt.
