Mark Hunt: UFC Sale = Dana White Spending Spree! And I Want Brock Again

The blockbuster sale of the UFC has heavyweight Mark Hunt seeing green -- while his loss to Brock Lesnar has him thinking rematch and hinting Brock might have cheated.

Mark was still a little bruised from the fight when we got him Sunday night outside the Monte Carlo Hotel and Casino. We broke the news to him about WME/IMG paying $4 BILLION for UFC, and he sounded very happy for his boss, Dana White ... especially Dana's bottom line.

Check out the video ... Mark also said he "has some complaints about the exemptions" Lesnar got.

When a UFC fighter comes out of retirement, as Lesnar did, you usually have to give 4 months notice and make yourself available for random testing. But the UFC waived that rule, since Lesnar just agreed to the fight in June.

Mark seems to be saying there's at least a chance Brock used PEDs -- which explains why he wants a second shot at him. Also puts Luke Rockhold's comment to us in context.
