Three months have passed since Renzo Gracie stepped onto the mat to face his long time rival, Kazushi Sakuraba, at Metamoris 5. Surprisingly, after that moderately successful event, there has been little mention of Metamoris 6. Behind the scenes, however, Ralek Gracie and his team have been working on a secret tournament that will take place this weekend in California.

The tournament will work in a round robin format, with each man competing a minimum of four 15 minute matches during the course of the day. While the scoring system has not yet been announced, it is believed that the total number of submissions scored by a grappler in his 4 matches will be weighted higher than winning on points.

The line-up for the tournament is yet to be released, but will consist of grapplers based in the California area, and is open for super heavyweights only. The winner will earn a spot on the main card of Metamoris 6.

While it remains to be seen who will appear in this secret tournament, it is certainly an interesting concept. A round robin tournament with each match to be released online over the course of a few weeks, with the winner getting a big contract with the promotion, it draws striking similarities with the UFC's flagship show The Ultimate Fighter.

Sources close to the event have stated that the tournament's winner will likely face Josh Barnett, who is coming off a stunning submission victory of Dean Lister at Metamoris 4.
