Alistair Overeem hasn't fought for Strikeforce since winning its heavyweight championship two years ago. But after winning an easy fight over the weekend, he'll fight again after just a week off, stepping into the cage to take on James "The Collosus" Thompson at Dream 12 on Sunday.

Dream has not yet announced the fight, but a source with knowledge of the situation tells FanHouse that it will take place on the card, which is noteworthy as the first time the Japanese Dream promotion will use a cage instead of a ring.

This past Saturday, Overeem needed less than a minute and a half to finish off Tony Sylvester with a standing guillotine in the first round, and he'll enter the cage with Thompson a heavy favorite to finish that fight quickly as well. Overeem is one of the best strikers in MMA, and Thompson has been beaten by knockout or TKO five times in the last three years.

Thompson is well known to fans as the guy who lost to Kimbo Slice on CBS in 2008, in what is still the most-watched MMA fight in American history. Overeem is, in addition to being Strikeforce's heavyweight champion, one of the world's top heavyweight kickboxers. After he fights Thompson, his next fight will be in the K-1 ring on Dec. 5, when he faces Ewerton Teixeira in the first round of the K-1 World Grand Prix 2009 Final.
