Do you think this is an illegal blow?

That's what we see here all the time though, it matters to some people who does it. If it's their hero then it was perfectly allowed and an in the heat of the battle kinda deal, but when it's someone they don't like it suddenly is a blatant foul.
It's like Chavez sr vs Taylor 1 compared with Bute vs Andrade 1... some of the same people that believe that Taylor should have been allowed to continue at 2:58 of the 12th so he could take the UD, were adamant that Bute should have been stopped while there was no time left in the 12th. Just because who is who, not because what's reasonable or what's not.

Don't like Fury and that was illegal and also a big influence on the fight result. Big Lennox fan, but that was just as illegal and also clearly influenced the fight.

 

Very effective. It was the KO blow, also being behind on the cards.

 

That's generally true, but sometimes you will see one fighter prying the gloves of his high guard opponent and is considered a legal tactic.

 

Take the Lewis clip. If Lewis grabs and pulls down on of Bruno's glove to create a brief opening that I believe is legal. That match that comes to mind is Loma vs Russell, Loma did it several times in mid distance and the referee allowed it.

 

I think you'd be warned by the ref for excessively doing it, but I don't think it's that much of an issue.

I'd take the view that if someone can hold their glove on you like that, you're probably not in a state to continue.

There's no way someone would do that unless they were unloading on someone either - if a boxer holds out their left arm like that, they're open to you're right-hand.

 

Clearly illegal. The fighter should be warned and penalized. If he continues it DQ him.

The foul I hate more, though, is the intentional follow through with the elbow. If I were a ref and I saw this it would be one warning, followed by a DQ because the impact on the fight can be so overwhelming.
