According to GracieMag.com, this could be the case:
The Carioca Gabriel “Napao” Gonzaga finally shall have a chance to avenge his knockout loss to Fabricio Werdum in Jungle Fight 1, in September, 2003. Marco Alvan, leader of Team Link confirmed today exclusively to GRACIEMAG.com that the battle between the black belts will take place in January, at UFC 80, in Newcastle, England.
As mentioned above, these two have fought in the past with Werdum knocking Gonzaga out early in the third round. It’s a pretty damn good fight, and if you wanna watch it, look no further than the MMA World League website. You can create a username and watch the fights for free on their channel. Also, Lyoto Machida vs. Stephan Bonnar is another interesting fight that can be viewed on the site.
Anyways, the only problem I have with Werdum making his return to the Octagon is he was just as boring as Andrei Arlovski was in their fight and he came out on the losing end of things. Why does he get a fight and Arlovski does not? I guess the obvious answer is Arlovski’s current contract situation, but giving Werdum a fight before Arlovski is just a slap in the face to “The Pitbull.”
