The last time the UFC held a pay-per-view in Las Vegas, UFC 143, we were treated to this gem between Carlos Condit and Nick Diaz. Will we get another killer main event Saturday at UFC 146?

HeavyMMA’s Duane Finley takes a look inside the UFC’s ever-changing welterweight division – where Georges St-Pierre was once as close to a lock as anyone in MMA.

UFC 143, which featured a welterweight interim title bout between Carlos Condit and Nick Diaz, drew 9,005 fans for a live gate of just under $2.4 million.

That didn’t take long. The fallout from Saturday’s UFC 143 main event between Carlos Condit and Nick Diaz now will apparently include a rematch.

Nick Diaz took home a paycheck for $200,000 for his five-round loss to Carlos Condit in the main event of UFC 143 on Saturday. Condit made $110,000 for the win.
