Well he wants to anyways.
IGN: Do you have a preference fighting in a ring or a cage?
Henderson: I fought in the ring for eight or nine years, but I'm getting used to the cage, and as a fan, I'd rather be watching it in a ring because you can see it easier. It also makes you be more skilled on the ground trying to position an opponent without the cage.
IGN: Strikeforce and Dream, a Japanese MMA organization, have an agreement to share fighters. Any chance you'll go to Japan?
Henderson: I'd love to go back and fight in Japan, maybe on their New Year's Eve card.
IGN: Is that allowed in your contract?
Henderson: Who knows, but I'm sure we could work something out.
