The former Australian and NSW enforcer is one of several Knights who will play their last games for the club on Old Boys' Day against the Dragons at Hunter Stadium on Sunday.

"I haven't really been in a situation like this where there's a farewell," Mason said after training on Thursday.

"I usually just take off mid-contract ... so there's no farewell, but in this case, it will be a privilege to do a lap of honour with all these guys and hopefully get a win.

"I'm not big on goodbyes or farewells ... I'm not that sort of dude. 

"I don't know how I'm going to react when I'm walking around with the boys, I'll just be happy when we win -- if we win."

Incoming Newcastle coach Rick Stone told the 34-year-old international last month that he was not part of the Knights' plans for next year, but Mason believes he has another two seasons left in him. 

After stints at the Bulldogs, Roosters and Cowboys, the Macquarie Scorpions junior wanted to finish his career in his home town but has no qualms about moving on. 

"It is disappointing, to be honest," he said.

"I was obviously thinking I was going to finish my career here, and I wanted to finish my career here, and I never really wanted to play for anyone else.

"So it was a bit of a shock to me, and probably all the fans and that as well, that I didn't get my contract renewed but that's footy and I'll just reflect on the three years that I've had here. It's been great.

"I've met some great people, the fans are awesome. I've always been a Newcastle boy at heart anyway so I knew what the fans are like. 

"I'll miss the fans and I'll miss the boys ... but it's not like I've been a one man, one club sort of player."

Mason has been linked to St George Illawarra, Newcastle's opponents on Sunday, but said he was yet to sign with a new club and said he would take the next few weeks to decide where he will play.

"I'll be playing next year. The Willie Mason saga continues, don't worry about that," he said.

"I've got a fair idea but I can't announce it all.

"I'm definitely going to play next year, I just don't know where.

"I'd look good in red and white, I reckon. Nah, I don't know mate.

"There's a lot of offers out there but it's just up to me..."
