saw the thread calling for diaz/silva being a NC cuz thats logical, no it isnt. Diaz lost, Silva failed his test, but Diaz also failed his, both under their normal license. Ill explain to you a situation where a fight shouldve been overturned but wasnt.. Lesnar vs Overeem Remember how the fight was almost called off because Overeem avoided a drug test and wasnt granted a license? During the pre fight conference, they were testing all fighters with a random test, including Lesnar , who took the test.. and Overeem got in his car and drove away immediately flew back to Holland and the fight was put in jeopardy. Overeem was given a hearing and given a conditional license where he would have to pass the pre-fight screening but also TWO post fight random screenings while under the license or else license would be invalid. Overeem failed one of those random post fight tests, making his license invalid, therefore didn't obide by the conditions given to him which gave him a license to fight Brock Lesnar, therefore the fight must be overturned to a No Contest. But nope, it was swept under the rug and handled as if he was not on a conditional license, and kept a win under Overeem's record since Lesnar was retired. source: The overeem/lesnar situation was one of the most overlooked so obvious cases of steroids in the UFC.
