I've been trying to find this MMA trivia fight for madd long. I vaguely remembered a Ken Shamrock fight where he beat the hell out of a guy in PRIDE but wound up tapping out because he was having heart attack. It had been so long since I'd seen it that for some reason I thought it was Cabbage that got this dub. And then the "heart attack" was later confirmed as "bad heart palpitations" which meant the "TKO by Heart attack" was removed from listings on places like wikipedia.
So for years I couldn't figure out if I'd imagined this ish. I was sure it Ken Shamrock and thought he was fighting Cabbage; I was sure he had a heart attack...and today, I stumbled on the actual fight.
