The now former DREAM middleweight fighter, Yoshihiro Akiyama, has signed with the UFC. Akiyama may most be known for his "greasing" tactic against Japanese hero Kazushi Sakuraba but should also be known for his impressive record as well.

Akiyama holds a victory over another recent UFC middleweight signee in Denis Kang, before Kang began his current slide.

The signing of Akiyama is a big one in the sense that he could be the guy who ends up truly challenging Anderson Silva for the middleweight title at some point down the road.

UFC President Dana White had this to say about Akiyama on UFC.com, "I can see him making an immediate impact in the middleweight division."

Satoshi Ishii, the Beijing Olympic gold medalist in the men's over 100 kg judo division, announced on Monday that he has started his career as a professional mixed martial arts fighter.

"I'm a professional fighter from today," the 21-year-old judoka said at a press conference on Monday, where he made an official announcement about his new career. "To become the strongest of the world's six billion people has been my dream since I was little. I think mixed martial arts is the toughest combat sports."

Finally putting an end to all the commotion regarding his retirement from judo, Ishii showed no regret about his decision. He revealed that he had decided to quit judo before he was chosen as a representative for the Beijing Olympics. "You only get one life, and I don't want to have any regrets. I will start as a beginner in mixed martial arts," said Ishii.

Although Ishii said he had yet to decide on when to debut and which MMA organization to join, he is expected to take part in the DREAM fighting event alongside his high school senior Yoshihiro Akiyama.
