Arlovski and NSAC Executive Director Keith Kizer

TJ De Santis and Josh Gross were live Wednesday for another edition of Beatdown on the Sherdog Radio Network. Joining them were Nevada State Athletic Commission executive director Keith Kizer and UFC heavyweight Andrei Arlovski (Pictures).

Tuesday the NSAC handed down a penalty to Nick Diaz (Pictures), who tested positive for marijuana after his bout with Takanori Gomi (Pictures) at PRIDE 33. Kizer joins TJ and Josh to talk about the situation, as well as other on goings with the commission regarding testing policies, and the possibility of allowing knees to the head of a grounded opponent.

Arlovski will be back in action at UFC 70 against Fabricio Werdum (Pictures). The Belarusian talks about his opponent, fighting in the newly revamped UFC heavyweight division, and what he sees in his future.

TJ and Josh take listener calls, e-mails, and touch on last weekend's PRIDE card.
