There hasn't been an event with this much Gracie flavor since the early days of MMA.
Three members of the sport's founding family will step into the cage at World Series of Fighting 5 in Atlantic City on Sept. 14: Rolles, Gracie, and Neiman.
Meanwhile, on the undercard, Gregor Gracie (7-3) takes on Rich Patishnock (5-1) at welterweight; and Neiman Gracie makes his professional debut against Darren Costa (0-1) in a middleweight fight.
World Series of Fighting announced full Gracie lineup on Wednesday.
All eight of Rolles Gracie's MMA wins have come via submission, as have six of Gregor Gracie's seven wins.
