BJ Penn's comeback fight will air live on cable television.
The five-fight main card will feature: Luke Rockhold vs. Chris Weidman for the middleweight title, Dominick Cruz vs. Urijah Faber for the bantamweight title, Max Holloway vs. Ricardo Lamas, Dan Henderson vs. Hector Lombard and Dustin Poirier vs. Bobby Green.
"This is great news," Penn told MMA Fighting. "All my fans from Hawaii get to watch me for free. I love that.
"But make no mistake about it, I'm the main event that night. Add all the fighter up and I'm more famous than every guy on the card put together."
The 37-year-old Penn (16-10-2) hasn't fought since his July 2014 loss to Frankie Edgar. Penn retired after the fight, however, he announced his intentions to resume his MMA career earlier this year after joining Team JacksonWink in Albuquerque, N.M.
"I want to come back," Penn said on a recent episode of "The MMA Hour." "I want to make a living. Of course, I want to make a living. But this is our honor. This is our f**king honor, and I wouldn't want anybody else but Greg Jackson behind me. Nobody is going to out-crazy me and f**king Greg Jackson."
Siver (22-11, 1 NC), also 37, enters the card on a two-fight losing streak. He most recently lost a unanimous decision to Tatsuya Kawajiri in June 2015.
