Lou DiBella wants to be clear on this topic. He’s not accusing Victor Ortiz of doping. He’s not making that accusation. He doesn’t think Ortiz is guilty of using performance enhancing drugs. But he will not allow Andre Berto, a fighter he promotes, to face Ortiz again in a rematch unless both fighters conform to some pre-fight requirements.

Ortiz won an entertaining decision against Berto on April 16 with both fighters touching the canvas. The win catapulted Ortiz to a mega-fight with Mayweather on Saturday. That bout had the makings of a mismatch before Mayweather landed what some perceived as a legal sucker punch, stopping Ortiz at 2:59 of the fourth round.
