"I really don't know [how long I'll keep fighting]. This could be my last fight. The last fight could have been my last fight -- I feel like that all the time. You never know. I don't need this, it doesn't have to stay this way. I've had a great time. I feel like I've had a great career. I took three Strikeforce belts. That's good enough for me. I'm here to do what I'm told, pretty much. I'm here to do what my coach [Cesar Gracie] tells me -- he really wants me to do this fight. He talked me into taking this fight. Dana White, Cesar -- they want me here, so I'm here. I don't fight my friends and I don't fight people I know. That's just kind of a rule I have. I don't care about the money, but he signed on to fight first. I never would have signed to fight first. I don't care how much money you put in front of me. I don't care if you put millions and millions and millions of dollars. Say whatever you want. Can't do it, man. If he signs first, then yeah. It's just a rule of mine."
