All 8 Prelims from UFC Live 4 to Stream on Facebook

---

The Ultimate Fighting Championship will stream the eight-bout undercard of UFC Live 4 “Marquardt vs. Story” in its entirety Sunday via social networking site Facebook.

The live online broadcast is set to begin at 4:55 p.m. ET (1:55 p.m. PT), four hours prior to the start of the main card on cable network Versus, according to a post on the UFC’s official Facebook page. A welterweight clash between Nate Marquardt and Rick Story headlines the four-fight televised portion of the show, which will emanate from Consol Energy Center in Pittsburgh.

Likely to top the Facebook stream is the 145-pound debut of Tyson Griffin, as the former lightweight looks to snap a three-fight losing streak by spoiling the UFC return of Manny Gamburyan. Also entering his featherweight debut on a three-fight skid will be onetime UFC title challenger Joe Stevenson, who tangles with ground specialist Javier Vazquez.

Six additional matchups will comprise the streamed segment of the event: Joe Lauzon vs. Curt Warburton at 155 pounds; Rich Attonito vs. Daniel Roberts, 170; Charlie Brenneman vs. T.J. Grant, 170; Nik Lentz vs. Charles Oliveira, 155; Ricardo Lamas vs. Matt Grice, 145; and Michael Johnson vs. Edward Faaloloto, 155.
