Trainer Glenn Rushton on Tuesday accused judge and former fighter Phillip Holiday of telling a friend Tszyu would win, sparking chaotic scenes at Tuesday's weigh-in.

Rushton also raised the issue of second judge Chris Condon owning the gym Tszyu has been training out of, pointing to his close association with Tim's father Kostya as another potential compromise.

The accusations caught Tszyu's camp off guard, co-promoter Matt Rose and manager Glen Jennings both firing back at Rushton for questioning the judges' integrity after initially having no complaints when the all-Queensland panel was established.

The Sydney-based duo labelled it an 11th-hour publicity stunt as a war of words played out during the official post-weigh in press conference in Townsville.

But just as Rose had slammed the accusations as "disgusting", chief judge Derek Milham, a long-time administrator and decorated referee, admitted Holiday had slipped up.

"He said to me he didn't predict anything, but he made the comment that if Horn loses it, it could be through cut eyes," Milham said.

"He's quite embarrassed and apologised to me about it. He's very, very professional.

"I think it's a bit of a tactic actually (from Horn's camp) and I've got full confidence in the guy. All you can do is take my word."

Global chairman of sanctioning body WBO Danny Leigh had no issue with Condon's links to the Tszyu camp but admitted Holiday had overstepped.

"I wouldn't be saying something like that, but in my opinion he's a professional," he said.

"Whatever happens in the fight, he will score the fight the way he sees it.

"We have selected the right judges for this fight. I have no doubt they will do the correct job.

"I'm very aware of the situation and they know their careers are on the line. If they do the wrong thing, the whole world is watching this."

Rushton said he had to "put it out there" given what he had heard.

"I don't like judges going in with a preconceived view of the outcome of the fight, all I've ever asked is just for a fair go and I don't want to say it after the fight because everyone will say it's sour grapes," he said.

But Rose slammed what he described "a typical (promoter) Dean Lonergan-Glenn Rushton play".

"It's pretty low to jump in front of national cameras to do so," he said.

"We're in Queensland, remember. We're a long way from Sydney.

"To question someone's integrity on a national stage is actually disgusting."

Tszyu weighed in at 69.1kg while Horn (69.8kg) snuck under the 70kg super welterweight limit for one of the most anticipated bouts in recent times.
