But he ended up acting as peacemaker as the Irishman and Malignaggi got heated in the ring.
Cortez said both fighters started off by firing verbal shots at each other – leaving the session out of control.
He told RUSH 93: “It was the real thing, I had to stop the action, say, ‘You guys are a little out of control here, you’ve got to stop this’. You know, they got a little rough.
“They were both roughing each other up and I had to stop the action like it was a regular fight.
“They were holding too much – they were trying to punch each other.
“So I had to call, ‘Time, alright guys you’ve got to stop this right now, I want a good, clean, strong – give me a sportsman-like conduct you understand?’.”
