GEELONG coach Chris Scott says his two-year contract extension is all but done and has pledged his committment to the club until 2019 and beyond.

There has been plenty of talk surrounding the 2011 premiership coach's immediate future, with reports suggesting issues exist between the parties over the contract's finer details.

But Scott said he was comfortable with where things sat.

"As far as I'm concerned, it's done. The actual signing of the papers is kind of irrelevant to the in-principle agreement," Scott said on Tuesday. 

"That's been the case for at least six months in my view.

"The club's committed to me and I'm absolutely committed to them.

"I don't really think there's anything more to add than that."

Scott is already contracted for this season, with his new deal to take him through until the end of 2019.

"I'm kind of sick of putting it off. I'm committed for at least that timeframe, and longer, to be frank," he said.

"That's the formal part of it.

"Even though you need to get some sort of certainly around the longer term future, my focus is really on the year at hand and has been through this pre-season.

"We've got some challenges in front of us and some great opportunity as well, so where I sit in the big picture is kind of irrelevant to me." 

The Cats will head to Perth on Saturday to face Fremantle on Sunday night at Domain Stadium in their season opener. 

Scott said recent draftees Brandan Parfitt and Tom Stewart, as well as rookie Zach Guthrie, would likely be named in Thursday's expanded squad. 

Guthrie, 18, needs to be elevated to play but the Cats have space, having moved Cory Gregson (foot) to the long-term injury list on Monday.

Former Carlton defender Zach Tuohy also looks likely to make his club debut after three impressive pre-season games. 

But Scott Selwood remains a few weeks away as he recovers from the toe injury he developed over summer. 

"He's had a super pre-season but just at the death got a bit of a sore foot, unrelated to his previous ankle injury," Scott said.

"That will hold him up for maybe another couple of weeks.

"He's on track to play in probably round three but it's a little hard to get certainty on it. 

"The problem he's had seems to have turned the corner so he'll be back into training with the group and looking to get going early in the year … it shouldn't take him too long to get into match shape." 

Young defender Jake Kolodjashnij has also "turned the corner" in his battle to get over a groin injury and is also poised to play in the early weeks of the season.
