Speaking at ANZ Stadium at the Blues' captain's run on Tuesday morning, Gallen anticipated the rulebook to be thrown out the window when the two teams come together. 

Gallen also expected debutants Josh Mansour, Matt Moylan, Adam Reynolds and Dylan Walker to fit nicely into the Origin arena and the hurt that comes with it.

"There's a lot of emotion and a lot of passion from both sides. We both love it, we both hate each other and at the end of the day we're trying to hurt each other," Gallen said.

While Gallen announced that this year would mark the end of his representative career with the New South Wales Blues, the inspirational lock forward has given no indication as to whether he'll run out for his beloved club again in 2017. 

Gallen has played 267 games for the Sharks since making his debut back in 2001 and has shown no signs of slowing down, averaging 147 metres per game this season. 

Gallen (4-0) and Williams (7-0) both remain undefeated in the heavyweight boxing division, however busy schedules in their chosen rugby codes have meant a bout has been almost impossible.

"We're talking about it but I suppose it's just hard to line our two schedules up," Cronulla forward Gallen told Fox Sports News.
