6. Jon Jones
While you can say that Jon Jones is a dirty fighter for his drug test failure heading into UFC 200, or the time he hid under a ring at a gym for 8 hours waiting for drug testers to finally leave, PEDs are not the reason Jones made this list. Frequent eye pokes and trying to break his opponent’s knees is why Jon Jones is on this list.
In 2014 MMA pioneer Bas Rutten called Jones out for his frequent eye pokes in a bout against Glover Teixeira.
“He knows exactly what he’s doing at any given time, and his fingers were definitely in his face – and for a long time. He was constantly rubbing them in his face.” Said Rutten.
Jones has also been called a dirty fighter by Quinton “Rampage” Jackson, who took issue with the way Jones uses kicks that are aimed directly at his opponent’s knee. Such kicks are actually banned in California, but legal in most places. Jackson claims that he has suffered knee problems since taking those kicks from Jones.
