The bell goes off just as the 2nd last punch lands, mid-combo and before the ref has reacted at all.
In MMA, that is simply not a foul. The ref stops the round, not the bell. In boxing I am less sure of the rules regarding whether it the bell itself or the ref, and I can't find anything official either way. Can anyone help?
I find it ridiculous to expect the Venezuelan to immediately react and stop his in that situation when he was trying to finish - as if in that split second your brain is focusing on the bell and not getting your opponent out of there - and even more ridiculous to DQ him.
