Australia's IBO cruiserweight champion Danny Green says challenger Antonio Tarver is a "piece of meat" he has to break down in Wednesday's world title fight at the Sydney Entertainment Centre.
Green was playful and fiesty on Monday as he responded to comments made by the Tarver camp.
Responding to the summation of his style as "primitive" by Tarver's veteran trainer Jim Williams, Green brought a couple of caveman clubs to the main pre-fight media conference.
The champion's camp was also less than impressed that Team Tarver had commented on Roy Jones' complaints about the wraps Green used on his hands for that fight.
"Affectionately, the Americans have sometimes been flagged as 'septic tanks' and there's a reason for that, because there's been nothing but crap come out of their mouths, so far," Green said.
Green says he regards 42-year-old four-time world light heavyweight title winner, Tarver, as the toughest challenge of his career.
"We are well and truly aware of what we are up against in this fight. He's a phenomenal fighter," Green said.
"He's a four-time world champion and a future Hall of Famer, but the respect is gone as far as a fighter and as a human being.
"When the bell goes, he's a piece of meat that's in front of me that I have to break down, chop up and do my job again."
Tarver says he is approaching Wednesday's bout as if it will be the last of his stellar career.
"I just personally feel they picked the wrong guy. They thought that an old, slow, 42-year-old guy would be showing up on Wednesday night," Tarver said.
"But that's not the case. You've got a hungry, determined assassin that's showing up."
