Which Heavyweight Champs (apart from Vitali Klitschko) were never knocked down?

[BRITISH LlON]

Vitali was never knocked down in the pros. And I also believe Nikolai Valuev never got dropped (he was stunned by Bergeron and Haye, but never went down).
Which other Heavyweight Champions were never knocked down? I can't think of any right now.

Oliver McCall.

Oliver McCall.

Yes sir. McCall had an iron chin; isn't it interesting that he was such an emotional guy, and so tough at the same time? I remember he had that ritual of crying when he walked to the ring and sometimes during the introductions. But it wasn't looking "unmanly" or anything, it was just HIS thing.
In the Frank Bruno fight he was crying all the way to the ring, it is one of the most weird and special moments I ever witnessed in boxing history. (And I don't mean that in a negative way)

Sugar Nikolai Valuev.

The only one I can think of is former WBC heavyweight champion Oliver McCall who has never been knocked down to my knowledge.
