9. Mirko Cro Cop
While Mirko Cro Cop might be reviving his career to a certain degree in Rizin, he’s perhaps not thrilled at how his UFC career came to an end.
The popular Croatian kickboxer admitted in November 2015 that he used human growth hormone to heal a shoulder injury. While his tests would come back negative, USADA suspended him 2-years since he admitted to it. That’s a nice reward for honesty.
Instead of sitting out the suspension, however, he came to terms on his release from the UFC and now fights for a promotion with less strict drug testing rules.
