The biggest story in the UFC remains Alistair Overeem's positive test for elevated testosterone levels ahead of his scheduled UFC 146 challenge for Junior dos Santos' heavyweight title.

Dana has been quiet on the Overeem front since that point, seeming to have decided it was for the best to not lose his mind in public. In fact, that's exactly what White told reporters at the press conference for UFC on Fuel TV 2 (via MMA Fighting):
"I will snap and freak out and I don't want to do that," White told reporters following the conclusion of the press conference. Link
