XFO 39 goes down tonight at the Sears Centre Arena in Hoffman Estates, Illinois, featuring Jeff Curran‘s “win or retire” match against Billy Vaughn, Jamie Varner‘s first post-WEC match against Tyler Combs, and a women’s bout between the lovely Felice Herrig and 7-4 Tulsa-based scrapper Nicdali Rivera-Calanoc. At yesterday’s weigh-ins, Felice and Nicdali produced one of the greatest staredown photos in recent memory. (Whether you prefer this one or Anderson Silva vs. Vitor Belfort pretty much depends on if you prefer chicks or dudes. Sorry. That’s the deal.) XFO 39 will be streamed live on alienwarearena.com/mma; the card kicks off at 7 p.m.
