MGM Grand, Las Vegas - The insults were flying during the final press conference for Saturday's Premier Boxing Champions card on NBC. Adrien Broner takes on Shawn Porter in the televised main event.

During the final presser, Broner and Shawn's father/trainer Kenny Porter were ripping into each other.

Kenny lashed out after Broner asked Floyd Mayweather Jr. - 'If I kick Shawn's ass and then I kick his daddy's ass - do I get paid twice?'

"You probably going to need to get paid twice to pay all that child support. Pay all those taxes, 15% for the first baby, 10% for the second baby. 10% to that trainer...20% to.......what you got? You don't want talk. We're gonna take you to zero now. I know you already spent the advance on this one. You already spent the advance," Kenny said.

"We're training to punish him. We're not training to knock him out. We're training to punish. Every time he goes down, we're going to wait for him to get up and punish him some more. After this fight he's going to be AB - absolutely broke."
