Plays of the Week
From Red Devil debuts to slippery Swans, these are the most exciting, silly and downright crazy plays in the sport world this week.
The three-time former world champion weighed in at 86.85 kilograms on Tuesday, more than 3kg lighter than 34-year-old Watts (90.25kg).
"Kane has got youth and size and a nothing-to-lose attitude, which makes him very dangerous," Green said. "I've been doing this for a long time, but you still get nervous any time someone's trying to knock you out.
"It [the weight difference] is going to be eight or nine [kg] by the time of the fight, but I don't give a damn."
Green said he and arch rival Anthony Mundine verbally agreed to a rematch when they bumped into each other at Sydney Airport recently.
"We've agreed on some terms to make the fight go ahead, but I've set that aside because tomorrow night it's game on," Green said.
"It's very hard not to look ahead, but I've been knocked out before and it's not pleasant and I don't want it to happen again. I know what it feels like being on your back looking up at the lights and the crowd is quiet. I don't want that feeling again.
"I'm a blown up light-heavyweight, but I've fought many bigger guys than Kane and I can hang with the big boys.
"I'm cherry-ripe and feeling great. I'm not a natural cruiserweight and I've had to campaign that way. He's a big, strong lad and I'll have my work cut out, but I'm pumped and ready to roll."
On whether he could be rusty, Green said: "The guys have been working me hard. When the bell goes and the guy starts firing them at me, that's when that will be answered."
It is believed Mundine will be ringside at Hisense Arena, but Green said he must shut that out of his mind.
"This [Watts] is the guy who's trying to knock me out, not the bucket [mouth] sitting at ringside," he said.
Watts, from Melbourne bayside town Mornington, is hoping to feed off the local support.
"I've got my own bit of history to write here. I've had awesome sparring leading up to this and the training camp has given me a dream run," he said.
Former AFL footballer Kane Pettifer is fighting a light-heavyweight bout against Paul Gould on the undercard. Pettifer, who played 113 games with Richmond before retiring in 2009, had one previous fight in December 2014.
