Paulie M dropping the stone man Lovemore N'dou, wasn't hurt at all, it was just a huh look on his face that he got dropped
this is absolutely correct. there are three very different things: (a) a slip/not a knockdown; (b) a glove-touching-canvas 'technical' knockdown caused by a punch; and (c) a 'proper' flash knockdown, where a fighter's legs give way completely as a result of a punch, causing him to sit or lie on the deck, or at the very least end up with both hands and knees on the deck. one of my favourite fights, hamed-kelley, has examples of all of these, e.g. hamed suffers (c) in rd 1 and (b) in rd 2 and 4, kelley gets knocked down properly more than once but also does an (a) in i think rd (2).
Any time someone is knocked down but isn’t otherwise hurt or affected beyond that moment. I’d say either situation you described fits, but the latter is the one that springs to mind when I hear flash knockdown”.
I would add another one, or a mix between (a) and (b), "a slip because of a punch". You are offbalance and a punch sends you to the ground even if you are not hurt at all. And it is a legit KD that should have a 10 count and a point deducted. Some people think that those are not legit KDs, but they are, since the cause of your "slip" was a punch, no matter if it didnt hurt you. I assume that it is what the OP called "a purely balance KD".
It depends on where you're from. British fighters will typically bounce right up completely unhurt from shots which would lay most non-British fighters out cold on their backs.
Simply put: it's a knock down that happens very quickly from a punch that isn't too hard at all but still enough to make contact and cause the fighter to hit the canvas. Loss of balance or slip while a punch made contact may be involved. Fighter quickly gets up before the count even starts and is visibly unshaken, unfazed or hurt by the punch.
He was talking about a different form of unruly penetration. https://en.m.wikipedia.org/wiki/I_know_it_when_I_see_it
Yeah that’s exactly how he uses it in the show. Exact quote, can be used for a myriad of situations. Fight wise, oskee had some flashes early on then smoked them a round or a minute later
Both definitions are commonly used and correct depending on context. It can be a case where a shot technically lands (and may or may not directly catalyze someone touching canvas with a proscribed body part) but where the person is hurt. It can also be a quick unseen shot that "short-circuits" the brain and monetarily, very briefly hurts you enough to drop you but from which you recover almost instantaneously and shoot right back up with no lingering cloudy-minded effects. Neither is the real definition, they both are. Basically any knockdown that doesn't even remotely approach being so authoritative that any suspense or drama exists regarding it potentially being a fight-ender. Flow chart: Was it a balance issue/somebody already falling due to either a rough clinch break, headbutt, shove, perambulatory malfunction, tripping, wet spot, whatever and there happened to be a punch connecting on their way down or right before the descent started? If yes: flash. If no: proceed to next question. Did the knockdown seem majorly and lastingly hurtful? If yes: no flash. If no: proceed to next question. Did the downed combatant shake it off immediately and get up with no apparent loss of "legs"? If yes: flash If not: probably not what you'd call a flash KD.
Funny, all the years since that happened, never heard it called a flash knockdown. I guess it kinda "qualifies" as a F KD (that acronym looks strangely offensive lol), as Ali got up immediately & didn't appear hurt, though he was exhausted and may have been showing the effects of that. Interesting. Speaking of Ali, wasn't that the legendary "'Enry's Hammer" that Henry Cooper hit a wide-open Ali with & cracked him with everything he had? The rest is history, as they say.
Every punch that knocks Fury down is a flash knockdown because he'll always get back up and get stronger from it.
