That's a different rumor LOL everyone keeps saying that. That was another rumor for the X-2 MMA promotion. I actually spoke with their matchmaker about it, the rumor as I posted it was totally legit. Obviously no one expected it to happen.
This is a different rumor. The WFA is interested in getting Goldberg to fight for them. They pulled Bas Rutten out of retirement after 6 years something PRIDE and UFC couldn't do, and they out-bid the UFC for Rampage, so I guess it's possible but I seriously doubt Goldberg ever fights in a pro MMA bout.
