It is interesting to note that Nick Diaz has apparently the highest reported salary of any welterweight not named George St-Pierre, Matt Hughes, or BJ Penn, and that Gilbert Melendez is now apparently the highest paid lightweight under the Zuffa umbrella.

The Strikeforce card wasn't the only major combat sport event. Golden Boy Productions hosted their "Action Heroes" card - with the aid of Showtime's rival, HBO - the same night. It is only fitting that we also publish the released payout for that card from the Nevada State Athletic Commission, since Brent Brookhouse recently posted an article that compared the pay structure of boxing and mma:

Erik Morales $250,000 plus an undisclosed pecentage of payperview sales and Mexican TV licensing
