World Series of Fighting (WSOF): Paulo Filho out, Elvis Mutapcic in

World Series of Fighting (WSOF) is making some changes behind the scenes in the middleweight division, recently announcing it would be parting ways with embattled Brazilian basket case Paulo Filho. In his place will be Maximum Fighting Championship (MFC) 185-pound kingpin Elvis Mutapcic.

MMA Junkie brought word of the changes earlier today.

Filho was handily defeated by David Branch last month at WSOF 2: "Arlovski vs. Johnson" at the Revel Casino in New Jersey. His putrid performance, coupled with his usual pre-fight shenanigans, once again proved that what little value is left in his name is not worth the aggravation.

The results (see them here) speak for themselves.

That's probably why the WSOF matchmakers were in such a hurry to gobble up Mutapcic. The 26 year-old Iowan is 13-2 overall with five straight wins and 11 finishes. In addition to competing for MFC in Canada, "The King" did stateside work for Shark Fights and Midwest Cage Championship (MCC) right in his own backyard.

Mutapcic knocked out Ultimate Fighting Championship (UFC) middleweight hopeful Cezar Ferreira in Aug. 2011.

No timetable has been established for his debut; however, an appearance at WSOF 3 on June 14 in Las Vegas is not out of the question. That depends on how quickly the promotion is able to match him up, which could be a challenge with such a limited roster.

Though I hear Dave Branch has no plans that day.
