Another chin chiselled by zeus himself has been cracked tonight, all that remain are
Bj Penn (yet to even be knocked down)
Shogun
Diego
I believe Eddie Alvarez has earned his name on the list, but thats about it as far as I can remember.
Hunt?
Arse Face - Hunt?Came here to say this
Gomi remains uncracked
Ahem..Roy Nelson reigns supreme in my mind(despite his TKO loss to Arlovski). 
Well I think Dan has been dropped worse in that past, he wasnt out cold. He gets dropped all the time.

Nick Diaz? Gets dropped but not knocked out.

Dan aint never been floored like that twice in a matter of seconds.
Arse Face - Hunt?I think OP means people who haven't been KO'd but yes hunt certainly does have a great chin
He wasnt knocked out either though, TKO, his chin saved him as usual from being out cold.

Who is BJ Penn?
Wasa-B -eXtv - Gomi remains uncracked
Its been cracked for a while.
He got stunned by a hard shot from Diaz when he left himself open but apart from that, when was the last time Gomi was dropped or rocked?
horn
RearNakedToke -I shouldn't specified I guess; I meant add Hunt to OP's list of legendary chins that were dethroned.Ice Cold Igors Right Hand -Manhoef cracked it before JDS kicked him.Arse Face - Hunt?Came here to say this
