Dream may have crowned two new champions just days ago in Yokohama, Japan, but the promotion has no time to relax with another event looming a little more than two weeks from now.

With the book on the Dream featherweight grand prix now closed, promotional event producer Keiichi Sasahara announced on Friday the addition of two middleweight bouts to Dream 12 on Oct. 25 at Osaka Castle Hall in Osaka, Japan. Destructive Dutchman Melvin Manhoef will take on Croatian Zelg Galesic, while former World Extreme Cagefighting middleweight champion Paulo Filho will meet South Korean judoka Dong Sik Yoon.

Dream 12 will be the promotion’s first experiment outside of a ring. The event will be contested in a hexagonal cage, with three five-minute rounds, as opposed to the standard 10-minute first round followed by a five-minute second period. Dream officials have indicated they expect cage events to become annual occurrences.

Manhoef has not seen mixed martial arts action since July 20, when he was submitted by the aforementioned Filho in a brief but wild affair at Dream 10. However, he has remained active in the stand-up world, going 2-1 under kickboxing rules with a pair of stoppages over Ramazan Ramazanov and Denes Racz; he dropped a unanimous verdict to rival Remy Bonjasky at the K-1 World Grand Prix Final 16 on Sept. 26.

Conversely, Galesic has not fought in more than a year, having been submitted by Ronaldo “Jacare” Souza in the semi-finals of Dream’s middleweight grand prix in September 2008. Galesic was scheduled to meet Brazilian kyokushin star Andrews Nakahara at Dream 8 in April before a failed blood test due to exhaustion and overtraining nixed the bout.

Following his July win over Manhoef, Filho earned a tepid and inactive unanimous verdict over Alex Schoenauer in his native Brazil. Yoon, a loser of three straight, returns to the ring following a grisly foot injury sustained in his July 20 bout with Jesse Taylor. Yoon suffered the injury while defending a Taylor takedown just 62 seconds into the match.

The two additional bouts join the previously announced contests pairing Bellator champion Eddie Alvarez with hot prospect Katsunori Kikuno, Cage Force titleholder Kuniyoshi Hironaka with fast-rising South Korean Won Sik Park and one-time WEC champion Chase Beebe with Yoshiro Maeda. Strikeforce heavyweight champion Alistair Overeem, Dream welterweight champion Marius Zaromskis, Daisuke Nakamura, Kiyoshi Tamura, Myeon Ho Bae and Nakahara are all scheduled to compete against yet-to-be-named opponents.
