NAKIA Cockatoo appears unlikely to start in the sub's vest again if he's selected for Friday night's big game against Collingwood.

The highly-rated youngster has begun the Cats' past two games in the green vest, but Chris Scott has flagged the potential for him to be in the starting 21 this weekend.

"The likelihood is that he wouldn't play as the sub in his next AFL game," Scott said on the latest episode of Tweet The Coach, brought to you by Momeuntum Energy.

"But if he does it's not the end of the world for him.

"At least we know that he can have a big impact for us in that role."

The latest episode of Tweet The Coach also features Scott's thoughts on:

* Nathan Vardy's comeback game

* Whether the players and coaches are confident that the team can still make the finals

* The reasons that Jimmy Bartel has been playing in the backline
