The winner of the tournament will face Fighters.com’s ninth-ranked middleweight “Grabaka Hitman” Kazuo Misaki (20-8-2) for the first-ever middleweight belt 4 January in Saitama at Sengoku 7.

Kazuhiro Nakamura (12-8) will face Yuki Sasaki (22-14-1), and Jorge Santiago (18-7) will face “Afghan Killa” Siyar Bahadurzada (14-3-1).

The event already features a lightweight tournament to determine an opponent for Fighters.com’s second-ranked lightweight “Fireball Kid” Takanori Gomi (29-3) at Sengoku 7 for the title.

The bouts remaining in the lightweight tournament are Satoru Kitaoka (21-8-9) versus sixth-ranked Eiji Mitsuoka (14-5-2), and Kazunori Yokota (7-1-3) versus Mizuto Hirota (10-2).

WVR also announced that Fighters.com’s Fighter of the Month “King Mo” Muhammed Lawal (1-0) will fight, although an opponent has not yet been determined.

“GameBred” Jorge Masvidal (14-3) versus Seung Hwan Bang (5-2) is also official.

Joe Doerksen (40-12) revealed through MySpace Tuesday that he has agreed to fight Izuru Takeuchi (25-9-6).

Lawal won his MMA debut in September, TKO’ing the more experienced “Diesel” Travis Wiuff (53-12) in the first round.

Masvidal defeated “Lion” Ryan Schultz (20-11-1) with a first-round TKO at the same event.

Bang lost his last fight via unanimous decision to Gomi in August.

UFC veteran Doerksen won a split decision over John Meyer (5-3) in August.

Shooto and Pancrase veteran Takeuchi won his last fight with a heel hook submission over Junior Santos (0-1) in June.

Why?

(Well, besides the obvious jack the UFC stands to profit on the main event.)

But, UFC President Dana White himself has claimed Penn’s best weight class is 155 pounds; and, Penn made much ballyhoo about getting serious and slimming down to 155 pounds, his natural fighting weight.

Penn has never fought above 155 with a physique that could be described as anything but “pudgy”.

Penn is also 0-2 in his last two 170-pound fights in the Octagon, which must make UFC welterweight contenders wonder if they can get some Vaseline.

In Saitama, north of Tokyo, 24 August, top lightweight contender “Fireball Kid” Takanori Gomi (29-3) won a unanimous decision versus tough, but relatively unknown Korean champ Seung Hwan Bang (5-2).

The tougher-than-expected struggle probably did more for Bang than Gomi, whose commitment to Sengoku has left him with few top ten challengers since the demise of PRIDE.

On the undercard, sixth-ranked Eiji Mitsuoka (14-5-2) shutup brash Brazilian Rodrigo Damm (8-2) in a first-round rear naked choke submission.

Mitsuoka was competing in the first round of Sengoku’s Lightweight GP, the winner of which will challenge Gomi.

Fifth-ranked “Muscle Shark” Sean Sherk (32-3-1) will come back from his May loss to Penn to fight worthy UFC challenger Tyson Griffin (12-1) in Chicago 25 October.

Seventh-ranked “KenFlo” Kenny Florian (10-3), who was cheated out of his title challenge versus Penn due to the St. Pierre match-up, will have to take out his frustrations on “Daddy” Joe Stevenson (29-8) in Las Vegas 15 November.

DREAM hasn’t announced a rematch between third-ranked Eddie Alvarez (15-1) and fourth-ranked DREAM champ “Hellboy” Joachim Hansen (19-7-1); but, Fighters.com would be surprised if Alvarez doesn’t get first dibs on the champ he already beat.

If he doesn’t, he and Florian can share a bottle of Vaseline with the UFC welterweight contenders.

The bottom of the top ten, eighth-ranked Kotetsu Boku (13-5-1), ninth-ranked “Tobikan Judan” Shinya Aoki (17-3), and tenth-ranked “JZ” Gesias Calvancante (14-2-1) were out of the loop last month and have no announced match-ups to report.

September Lightweight Rankings

1. “Prodigy” B.J. Penn (13-4-1)

“Prodigy’s” return to lightweight quickly resulted in UFC gold with two stoppages over Joe Stevenson and Jens Pulver. In May, he dominated the best the UFC had to offer in a TKO of Sherk; but, he won’t stay at 155-pounds,

2. “Fireball Kid” Takanori Gomi (29-3)

Gomi avenged a 2006 blip to Marcus Aurelio with a stoppage on NYE the same year followed by a stoppage of Mitsuhiro Ishida.  A year-long layoff keeps Gomi from ichi-ban, but he returned in March with a stoppage of Duane Ludwig.

3. Eddie Alvarez (15-1)

Since dropping from welterweight for the DREAM Lightweight GP, Alvarez has been relentless in a stoppage of Amade, UD over Hansen, and TKO of Tatsuya Kawajiri.  Only an injury prevented him from securing the DREAM title.

4. “Hellboy” Joachim Hansen (19-7-1)

“Hellboy” shocked Aoki with a TKO in a rematch of the fight that introduced the gogoplata to MMA.  He also holds a UD over Boku, but decision losses to Alvarez and Mitsuoka hint at inconsistency.

5. “Muscle Shark” Sean Sherk (32-3-1)

“Muscle Shark” had been on the shelf for nearly a year since decisions over Franca and Florian.  In his return, Penn outclassed the wrestler to a TKO, leaving both top UFC lightweights with slim competition within the promotion.

6. Eiji Mitsuoka (14-5-2)

Mitsuoka followed up a majority decision over Hansen in Shooto by handing SpiritMC 155-pound champ Kwang Hee Lee  his first loss in Sengoku.  Only a SD loss to Boku in Cage Force tarnishes his two-year record.

7. “KenFlo” Kenny Florian (10-3)

Florian is a finisher since losing a UFC title challenge to Sherk by UD. “KenFlo” is ready for a second title challenge after a dominant UD over top UFC contender Roger Huerta.

8. Kotetsu Boku (13-5-1)

Boku risks being labled a fluke.  After a SD over Mitsuoka, Boku has dropped consecutive decisions to Artur Oumakhanov and Hansen.

9. “Tobikan Judan” Shinya Aoki (17-3)

Aoki had eleven straight wins, including MMA’s first gogoplata stoppage over Hansen, topped only by MMA’s first gogoplata stoppage from the mount over Katsuhiko Nagata.  But, Hansen exacted revenge with a TKO in the DREAM GP final.

10. “JZ” Gesias Calvancante (14-2-1)

“JZ” has brushed Andre Amade, Vitor Ribeiro, and Nam Phan off his shoulders with stoppages since a MD over Caol Uno in ’06, part of 13 straight without a loss until losing a UD to Aoki in April.

Mitsuoka advanced to the second round of the Sengoku lightweight tournament, the winner of which will fight second-ranked “Fireball Kid” Takanori Gomi (29-3).

Gomi headlined Sengoku’s fourth battle with a narrow decision over DEEP Lightweight Champion Seung Hwan Bang (5-2).

It was Bang who provided the bang in his stand-up exchanges with the notorious big-puncher Gomi.

But, Gomi edged Bang with stinging leg kicks and championship conditioning for the decision.

Seventh-ranked middleweight “Twinkle Toes” Frank Trigg (17-6) grounded Olympic gold medalist judoka Makoto Takimoto (4-5) at will with single- and double-leg shots, then rained a dominant G’n'P over three rounds to pick-up a unanimous decision in his first fight since December 2007.

In other lightweight tournament match-ups, PANCRASEism’s Satoru Kitaoka (21-8-9) tapped eighth-ranked welterweight Matt Hughes‘s H.I.T. Squad pupil Clay French (16-3) in an Achilles lock at 31 seconds of round one.

IFL Champion “Lion” Ryan Schultz (20-10-1) suffered a surprise second-round knockout by Cage Force Lightweight Champion and former Shooto rookie champion Mizuto Hirota (10-2).

Finally, in an ugly-as-sin slog, Grabaka’s Kazunori Yokota (7-1-3) won a unanimous decision over Slovenian “Zelva” Bojan Kosednar (6-2), who earned two yellow cards for holding and grabbing the ropes.

Yokota saw yellow too for causing Kosednar to see stars with a low blow.

In undercard fights, heavyweight Dong Yi Yang (3-0) TKO’d Polish judoka Pawel Nastula (1-4) in a strange decision by the referee.

In the second round, Nastula worked an armbar, but released it for Yang to rise.  Nastula remained grounded and pointed to his cup, prompting to referee to call the fight at 2:15.

Europe Top Team light heavyweight Moise Rimbon (13-7-3) tapped Aussie kickboxer Peter Graham (0-2) in rear naked choke at 42 seconds of round two.

Valentijn Overeem (26-22) knocked out Yoshiki Takahashi (28-24-3) at 2:43 of round one with a flying knee.
