Kimbo and company officially wrapped filming this week, with the show debuting on Spike TV on September 16th, immediately following their LIVE broadcast of Ultimate Fight Night 19 in Oklahoma City, Oklahoma.

Accompanying the street fighting legend this season is former IFL heavyweight champion Roy Nelson, former UFC fighter Wes Sims and a few former NFL players.

Here is the complete cast of heavyweight characters on this season’s show (courtesy of Spike TV):

Marcus Jones (4-1): The 6-foot-6, 260-pound 35-year-old Jones is the most prolific of the show’s NFL quartet. While playing defensive end at the University of North Carolina, Jones was an All-American and the 1995 ACC Defensive Player of the Year and became the 1996 first-round draft pick of the Tampa Bay Buccaneers. After eight successful years in the NFL, he joined Gracie Tampa and made the transition to MMA.
