World Series of Fighting (WSOF), the budding mixed martial arts (MMA) promotion headed by kickboxing legend Ray Sefo, has announced its fourth and fifth events on NBC Sports Network for later this year.
WSOF 4, which does not have a main event or any announced fights at this time, is set to take place Aug. 10, 2013 from inside the Citizens Bank Arena in Ontario, Calif., an arena that can hold just over 11,000 spectators.
Sefo revealed the news on Thursday's (June 6, 2013) WSOF 3: "Fitch vs. Burkman" media conference call.
While no match ups for the card were announced, Sefo did state that former Ultimate Fighting Championship (UFC) lightweight and featherweight competitor Tyson Griffin is expected to make his WSOF debut on the card against an undetermined opponent.
Details regarding a fight card and on-sale date for tickets are expected to come out in the next few weeks.
Also on the call, Sefo stated that WSOF 5 is likely to go down Sept. 14, 2013 in Atlantic City, N.J., but did not make any further comments on that event aside from the fact he expects former XFC champion Nick Newell to make his organizational debut.
