Well, I never actually saw the PPV, but Uncensored 1999, Flair fought Hogan in a First Blood match (I think a Steel Cage was involved also) for the title. Flair ended up winning, but not because of the first blood match rule. I remember Hogan was busted pretty badly (not sure about Flair).
My memory's joggy as I didn't watch WCW in 1999, mostly because of the aftermath of the Fingerpoke bullshit. Can somebody elaborate on the First Blood Match?
