Former Autralian rugby league star and world champion boxer, Anthony Mundine, pulled Tillman to the ground before Williams' brother, John, tackled him into the boxing ring.

Both camps intervened to stop the escalating confrontation.

As Tillman was escorted from the gym Williams yelled: ''I'm going to f*** you up.''

''If he wanted to I could fight right now,'' he said.

''It's on.''

Mundine said Tillman was under a lot of pressure but it was no excuse for taking a cheap shot.

''I think he's flustered,'' he said.

''That was a very disrespectful thing to do. To dog shot someone like that, he's lost all respect and honour as a warrior and I sure do hope that Sonny makes him pay for that tomrrow night.''

Tillman weighed in at 128.4kg and Williams at 107.9kg.

Williams later took to Twitter to share his thoughts on the weigh-in bust-up saying:

"Thanks for the support peeps he had his free shot I'm sure he won't give me one tomorrow night!!"
