Leave it to UFC President Dana White to drop a bombshell on Twitter late at night.
That's exactly what he did tonight, though, when he announced that Alistair Overeem is officially out of the UFC 146 main event against Junior dos Santos on May 26, 2012, at the MGM Grand Garden Arena in Las Vegas, Nevada. He will be replaced by Frank Mir.
Taking off to Atlanta!!!! May 26 th is now Mir vs JDS for the HW title in Las Vegas at the MGM Grand.
