With a middleweight title tournament about to begin, the World Series Of Fighting will also use a four man tournament to crown their first lightweight champion. There are two fighters already announced for the tournament, they are Justin Gaethje and Dan Lauzon. The other two spots will go to the winners of the Nick Newell/Keon Caldwell and Tyson Griffin/Gesias Cavalcante fights, both of which are happening at the WSOF IV on August 10th. The tournament is expected to kick off before the end of 2013, most likely at an October and/or December WSOF card.
