David Tua has an absolutley monstrous chin i seen him take some killer shots to the jaw and just simply shake them off . He's never been ko'd i dont think hes ever been floored either.

Ike Ibeabuchi set a world record beating muhammed ali old 1 for most punches thrown in a heavy weight match and ike was a absolute savage and Tua holded it down even though he lost.

watch it
