UFC president Dana White has made public fights that were not yet fully signed, sealed and delivered. So he knows first-hand that premature announcements can come back to bite you.

As a promotion, the UFC has become accustom to rescheduling fights after injuries to the athletes. The latest, UFC middleweight champion Chris Weidman, is forcing White to take a different approach to his game.

“We’re still working on a lot of stuff,” said White, during an interview with MMAjunkie.com. “Ever since Weidman went down and needed knee surgery, we’ve been moving things around and shaking things up. I’m still working on all that.”

“All that” includes a rumored Dan Henderson-Daniel Cormier bout, along with where Chael Sonnen-Wanderlei Silva will take place.

“A lot of stuff was getting announced prematurely and that drives me crazy,” White said. “There was a lot of premature stuff out there about fights that were going to happen. Most if it is not true because none of it’s done yet.”
