Jacob Fatu may have been the one standing tall at the end of WWE Backlash on Saturday night, but the World Heavyweight Championship is still around the waist of The Tribal Chief. Roman Reigns had to utilize an exposed turnbuckle to finally keep the Samoan Werewolf down for three seconds, but he didn't stay down for much longer. A furious Fatu proceeded to cut down anyone who tried to stop him from carrying out a post-match assault on his cousin. He locked in the Tongan Death Grip and fought off numerous members of the security team while refusing to yield the hold. It'll be a much different story tonight when Monday Night Raw invades Knoxville, Tennessee. General Manager Adam Pearce, who was one of the victims of Fatu's meltdown Saturday night, says The Samoan Werewolf will be on the show this evening to take part in a Roman Reigns Acknowledgment Ceremony. What could possibly go wrong? . @jacobfatu_wwe is OUT OF CONTROL!…
