Michael Conlan has accused TJ Doheny of “talking s****” over the weight debate which erupted during Tuesday’s press conference.
It emerged that Friday’s contest will be fought at a 124lb catchweight, with the interim WBA featherweight title also on the line.
Doheny claimed he wasn’t aware of the late change until he arrived in Belfast at the weekend, and the 34-year-old raised the issue during Tuesday’s media event at the Balmoral Hotel, which sparked a heated war of words between the pair on stage.
Speaking to Belfast Live afterwards, Conlan said: “I will still make 124 and he still yapping and talking about discrepancies and s**** like that.
“I think it’s getting under his skin. I think he’s rattled. I just let him know I am not just sitting here. I am laughing at him.
“Have the b**** to take the fight.
“It is what it is and I look forward to going in there and putting on a show.
“If he wants to walk away he can walk away. We will get A, B and C in. There’s no problem with that.
“If that’s what he wants, that’s what he wants. But you don’t go through a 12-week training camp, away from your home in Australia. You don’t fly to Ireland, go through a public workout and all that, if you’re going to pull out.
“He isn’t going to pull out. He’s just talking s****. He is trying to get more money. Whether or not he does or not, it is none of my business.”
Former world super-bantamweight champion Doheny says he wasn’t made aware of the move from 122 to 124lbs until he arrived in Belfast on Sunday.
He told the BBC: “It looks like he can’t make the weight. I’ve been in training camp for the past 12 weeks and I have changed my body composition to get myself down into the super-bantamweight division.
“Now, all of a sudden I am being asked to move to featherweight. I’m in talks with my management at the minute and we are trying to rub out the discrepancies.
“At the end of the day it is professional boxing. Professional meaning you agree to a certain weight division and a certain category and you stick to it.
“You can’t go changing things up at the last hour.”
