CARLTON star Bryce Gibbs is on the verge of signing a new contract with the Blues.

Gibbs' current deal expires at the end of the season, which had fuelled speculation he would be a recruiting target for a cashed-up Greater Western Sydney, but the 23-year-old said on Wednesday that contract talks with Carlton had entered the final stages.

"As far as I know it's coming along no worries. Hopefully it can sort itself out in the next couple of weeks and we can put it to bed," Gibbs said at the launch of the Richard Pratt Cup at Visy Park.

"I'm very happy with how everything is going with me and the club and where we're headed, so hopefully it can sort itself out soon.

"I'm not one to say 'let's put talks off until the end of the year' - it just causes speculation and headaches and whatnot. The club is working with my management as we speak, and when the right deal is finalised and both parties are happy, I'm sure I'll sign."

The news of Gibbs' contract discussions is a shot in the arm for the Blues, who face their biggest test of the season when they take on Collingwood at the MCG on Friday night.

Gibbs believes Carlton will take its strongest line-up of the campaign into the much-anticipated clash, with Michael Jamison (back) and Nick Duigan (knee) possible inclusions as the Blues attempt to snap a five-game losing streak to the Pies.

"We obviously haven't beaten Collingwood for a few games now, and that always sticks in the back of your mind," he said.

"The crowd's going to get involved, it's going to be a great build-up, and we're looking forward to not only seeing where we're at, but looking forward to playing against a genuine top-four side … and seeing how we go.

"We know every time we play them it's going to be a tough match. We've got to be on our best game to take the four points. If we're off by five or 10 per cent or we have a lapse in a quarter it's going to hurt us, so we've got to be ready."

Defender Heath Scotland will take his place in the team just days after being charged by police for his part in an altercation at the Mulwala Ski Club in January, but Gibbs would not expand on a brief club statement released on Tuesday other than to say the 31-year-old was "fine".

Carlton and Collingwood will be playing for the Richard Pratt Cup, named after the former Carlton club president who lost his battle with prostate cancer in 2009, which is an initiative aimed towards raising awareness of the disease.
