The World lightweight champion, Juan Manuel Marquez, is defending his new strength and conditioning coach, Angel Hernandez, after reports came out revealing Hernandez’ shady past.

Hernandez was known as Angel Heredia and supplied performance enhancing drugs to Olympians, including Marion Jones and Tim Montgomery.

“If they want to do whatever doping or drug testing they want to do, Olympic-style, or whatever they want to do, I’ll do it. I’m prepared,” Marquez said.
