Just watch the first round he had with Shogun. That's all you really need to answer this question.
Once the two men hit the ground and grapple, Jones -
Attacks the trachea
Attacks the eyes
Headbutts
He does so all within a 3 minute span. The ref misses the headbutt, but the announcers do not. Also, he is warned for the eyes, and throat. Yes. He did all three fouls and was caught on two of them by the ref.
All three fouls are pretty blatant. Which is weird to me, as he would have won even if he didn't do them. They didn't give him some great advantage. So why do them? Fuck if I know.
And the really fucked up shit was the eye attacks with Rampage.
Rampage literally tells the ref to do his job, because the ref refused to address the foul.
Sadly the gif shrunk down when it was uploaded, but you can still see it. He goes for the eyes. The first one could be easily dismissed, but the second one that is like 2 seconds later is so obvious. He literally is walking at his opponent with his fingers fully stretched and keeps trying to jam them at the eyes. It's fucking funny how obvious it is. And the ref is just.... durrrrr.
So yea, there's four fouls in two fights for you. Not a point deducted... just mild verbal warnings.
