Ken Shamrock is currently penned in to face Pedro Rizzo and not Mark Coleman at Impact FC on July 17 in Australia, MMAFighting.com has confirmed with promoters.

I believe this is on the same card as Ninja- Jeremy May and I have read Semtex maybe fighting on this card too. Whoever wins this one should move into the top ten P4P discussion.
