Although not unaccustomed to losing, as he has lost several–though not many–matches in is long and storied wrestling career, that spans from collegiate wrestling to competition overseas.

After his first and only loss to current Strikeforce 205-pound champion Rafael “Feijao” this past Saturday, where the Brazilian Blackhouse stablemate floored the wrestling standout with knee-hook combo before ending the bout with elbows in succession to the head while a prone Muhammed attempted to lock up a single leg, manager Ryan Parsons confirmed with Sherdog.com that his fighter is undergoing some heavy-duty surgery.

With two surgeries being accounted for, Mo will have his left knee operated on, repairing his anterior and posterior cruciate ligaments, Parsons believes that his fighter will be sidelined for up to 9 months. Mo, though a true competitor, intended on fighting one more time before the surgery, but his manager insisted.

“Mo wanted to take one more fight, but we decided that this injury should be attended to first,” said Parsons after King Mo was observed by his physician just yesterday.

Some may remember Mo having had ACL surgery not all that long ago. After opening up his career with three consecutive TKO finishes under the Sengoku banner, Mo went to his first decision against Japanese veteran Ryo Kawamura in March of 2009.

It was later learned that Lawal tore his ACL during the contest and was later operated on, and made his return just five months later against Mark Kerr under the M-1 banner.

So, what does Lawal’s absence do to the 205 pound picture for Strikeforce? Immediately, Gegard Mousasi looks like the next logical step, since he is a draw with the fans of Strikeforce, relevant, and back on his winning ways since his loss to Mo, where he recently earned a first round submission win over UFC veteran Jake O’Brien.

Mike Kyle could also be up next for the Brazilian, who will undoubtedly want to exact revenge on the only man to legitimately defeat him convincingly.

So, who deserves the next crack at the title, and is Lawal’s injury hurting him or Strikeforce more in the long run?

“The Babyfaced Assassin” from Seattle tread the path of his catch wrestling forefather Ad Santel Wednesday by submitting Japanese Olympic gold medalist judoka Hidehiko Yoshida (7-6-1) by heel hook at 3:23 of round three at World Victory Road’s inaugural Sengoku fight card in Tokyo.

A century ago, Santel waged war with judoka and proclaimed himself the world judo champion after defeating fifth-degree black belt Tokugoro Ito.

“I revived this rivalry when I fought Kazuhiro Nakamura,” Barnett (21-5) told Sherdog.com. “And, so I’m keeping it going for this century now.”

The fight was the American’s first in MMA since losing a unanimous decision rematch with current interim UFC Heavyweight Champion Antonio Rodrigo Nogueira (31-4-1) on New Year’s Eve 2006.

His layoff had erased his name from most rankings which require activity in the previous 365-days; but, vanquishing the samurai establishes Barnett’s status as a top five heavyweight.

Also returning to active duty, former PRIDE Lightweight Champion “The Fireball Kid” Takanori Gomi (28-3) sliced open “Bang” Duane Ludwig (16-8) of Denver to earn a first round stoppage at 2:28.

Gomi had been out of commission  since tapping to Nick Diaz (15-7) in a gogoplata at PRIDE’s last American card in February 2007.  After Diaz tested positive for smoking a doob’, the outcome was deemed a No Contest by the Nevada State Athletic Commission.
