Is Ducking Below Waist Level Against The Rules?

You have to remember it's ok to do this to anyone else except Pacquiao thats the samething i was thinking

That's right, I remember that one against Solis. He was in panic mode trying to get away and was ducking really low and Pacquiao kept missing. Might be something Pacquiao can ask the ref on his next fight. The thing is, the risk is high, if Manny would have landed his left during those instances in my first gif, check out my sig, Bradley would have hit the canvas and I doubt he would have been able to catch his balance in time. Sometimes I was fearful that he'd get caught like this, but it worked out well with Tim.

I'm just not sure if that's against the rules. If it is against the rules, there were certainly numerous instances during the fight that the ref could have given Bradley the warning. Pacquiao missed a lot of punches when Bradley ducked way below the waist line. Reminded me of how Lucero fought Pacquiao. Another fighter who defended well against Pacquiao and was slowly finding his way back into the fight was Solis, he was also bending at the waist and Manny found it extremely difficult to catch him. We know how that ended though. But I can't recall one instance, or remember one, where the ref warned for such a thing. I'd like to know if someone has.

I always learned it is an illegal move because you are not suppose to punch below an opponents waist. Mike Tyson did it lots but wasn't called on it really but in amatuers you'll get warned

From what I've heard yes, but from the looks of it you would think it's not. Plenty of fighters are doing this.

In amateurs it is.
