WSOF officials made the announcement on Wednesday as Rolles will meet Derrick Mehmen in a heavyweight bout, Gregor faces Richard Patishnock at welterweight, and Neiman has been booked to meet Darren Costa in a middleweight bout.
WSOF 5 takes place on September 14th from Revel in Atlantic City and will be headlined by former UFC heavyweight champion Andrei Arlovski facing Mike Kyle.

Six of his seven career wins are by submission and this will be his first fight since being defeated by Steele. Patishnock (5-1) defeated Igor Gracie in his WSOF debut earlier this year and it was his second career win to take place in the first round.
Neiman Gracie (0-0) will be making his pro debut after having success as a grappler and trains under Renzo Gracie. He will meet Costa (0-1) who lost his professional debut earlier this year by TKO in the second round.
