I'm talking about when both guys land and both go down simultaneously from the same exchange. I know this is rare, but it's happened. I'm looking for examples, and in particular I remember it happening in a fight in the late 1970s or early 80s that was televised on a weekend afternoon, on ABC or CBS or maybe NBC (I'm thinking CBS for some reason). Anyone remember this one, or any other occurances?
Did this ever happen with Alexis Arguello (like earlier in his championship career, below lightweight), or am I misremembering?
