Alistair Overeem was pulled from the planned UFC 146 main event fight with UFC heavyweight champion Junior dos Santos late Friday night.

Now, UFC president Dana White has disclosed the reason for the decision to plant Frank Mir in Overeem’s place despite “The Reem” not being found completely guilty yet of elevated levels of testosterone.

“We were right up on deadlines for a lot of things we needed to do to promote a pay-per-view and I’m not very optimistic on Tuesday,” said White, during a recent interview with MMA Weekly’s Andrew Gladstone.

Overeem is set to go before the Nevada State Athletic Commission in regards to his test, hoping to earn his fight license from the commission.

During Saturday’s pay-per-view, the UFC promoted the Mir-dos Santos card, which obviously was one issue with not knowing what might happen with Overeem this coming week.

White added that he still feels like he can do business with Overeem, despite being upset after the drug test results came back because he disclosed Overeem had promised him he could pass any and all tests.
