Star midfielder Josh Kennedy is confident his injured teammates would make the right call should they declare themselves fit to play in Saturday's Grand Final.

Aliir Aliir (knee), co-captain Jarrad McVeigh (calf) and Callum Mills (hamstring) all took part in Wednesday's session at the SCG.

Midfielder Josh Kennedy dismissed his own niggle with a knee complaint, and said he wasn't worried about taking injured players into the match against the Western Bulldogs, given coach John Longmire's history of making tough decisions at the selection table.

"It's part of the game and part of the industry, and we'll do the best we can with the best 22 we take out there," Kennedy said.

"We know that 'Horse' (Longmire) and the coaching staff will make the right call and I've just got to worry about bringing my best on Saturday.

"There'll be a few nervous guys, but I have the upmost confidence that they'll be able to get through training, and we'll see how they go."

The Swans will go into the game as favourites over the Dogs, who could go into the match without a single player with Grand Final experience, if former Hawk Matt Suckling isn't selected.

Kennedy is among a host of players with premiership history in Longmire's side, but he said he doubted the Bulldogs would get caught up in the hype surrounding the game.

"I think if they were going to (get overawed) it would have already happened," Kennedy said.

"They've obviously got a huge amount of belief and trust in one another.

"They’re playing a great brand of footy which has stacked up (so far in the finals), so it's going to be a great contest.

"We're fortunate enough to have guys who have played before, whether it was 2006, 2012, or 2014.

"There's a lot of experience there and I think that’s helped a lot with a lot of our younger guys.

"We've also got a lot of trust in the way that they've gone about it over the last two weeks.

"They've stood up in big games and I'm sure they can do it again."
