By his own admission, UFC CEO Dana White has been talking about getting into the boxing game for a while. Apart from dipping the UFC’s proverbial toes in the water with things like Zuffa Boxing and the backing of the sport and boxers like Callum Walsh on UFC Fight Pass, it’s been much ado about little.

“There will be some big announcements soon. I never say anything I don’t do, ever,” Dana White said Thursday during the Walsh vs. Runowski Q&A. “We’ve been kicking the whole boxing thing around for a long time, but you’ve never heard me commit and say, ‘I’m in.’ I’m in.”
