So are you asking if anderson hasn't bled in the octagon or asserting it?I never saw him bleed in the UFC,not a single cut on him or anything like that.Crazy for his number of fights and he took many shots on his head.Is there any other fighter who kept his head clean ?
To answer the question in the thread title, he never had a cut but he did bleed in his mouth a bit in the first sonnen fight if you wanna count that.
To answer the question in op, maybe bj?
