The MMA World Series of Fighting roster boasts some of the world’s top fighting talent, including arguably the top 115 lb female fighter in the world, Jessica Aguilar.

But it’s at welterweight where the spotlight is shining now — with Jake Shields making his debut for the promotion at WSOF 14 this weekend in Canada.

Now, reports indicate that WSOF’s feared welterweight champion, Rousimar “Toquinho” Palhares, will soon meet a former UFC title challenger in Jon Fitch.

According to Guilherme Cruz of MMA Fighting, the bout will take place at WFOF 16 in December.

The bout will mark Palhares’ first defense of his MMA World Series of Fighting Welterweight Championship. The Brazilian grappler earned the belt with one of his trademark leg lock submission victories over Steve Carl back in March.

Fitch, long known for his presence in the UFC welterweight division, has fought three times for WSOF, earning a 2-1 record. His almost eight year UFC run included a decision loss to Georges St-Pierre in 2008, when the two met at UFC 87 for St-Pierre’s UFC Welterweight Championship.

Fitch and Palhares were expected to fight back in July at WSOF 11, but the bout was scratched as Palhares cited personal reasons.
