The cloud of mystery surrounding the main event at UFC 146 grew in intensity today when UFC President Dana White went on Twitter to update fans on the card’s status. While the outspoken executive didn’t address the headliner between Alistair Overeem and Junior dos Santos specifically, he did bring up the man who many have pegged as a replacement for Overeem if the disgraced Dutchman fails to obtain a license based on his recent drug testing results.

“Mir vs. Cain will happen,” wrote White on the social networking outlet, implying Frank Mir is still set to face Cain Velasquez on May 26 rather than being considered for a title-fight against Dos Santos. White has also said Dos Santos is still defending his belt at the event, leaving many fans to scratch their heads in an attempt to figure out the UFC’s post-Overeem plan.

Last week Overeem was found to have more than twice the level of testosterone in his system allowed by the Nevada State Athletic Commission. He has not spoken publicly on the matter yet though will need to do so in the near future if hoping to save face and maintain his role as the heavyweight division’s top contender. In order to receive a license Overeem will need to meet with the NSAC and have his “B” sample cleared, the latter being extremely rare when requested in similar situations.

With Mir and Velasquez seemingly out of the picture, if Overeem is yanked from the bout with Dos Santos, other possibilities are extremely limited and have even included a fan-driven attempt to put Mark Hunt in the mix.
