Defender Jamie Macmillan says his ankle has shown signs of improvement each day and admits the "fire still burns" from last year's preliminary final loss to the Sydney Swans.

The 23-year-old rolled his ankle in the fourth quarter of last Sunday's 17-point elimination final win over Richmond but managed to return to the field.

Macmillan said he would be fully fit for Saturday night's semi-final against the Swans at ANZ Stadium.

"It's a little bit embarrassing – I tripped over my own feet and rolled my ankle so I've only got myself to blame," Macmillan told NMFC.com.au on Thursday.

"It's got better every day since the game, and today, I'm not feeling it at all."

The Roos enter the semi-final against the Swans on the back of a six-day break following their memorable win over the Tigers.

Macmillan said the playing group would maintain its normal routine ahead of the trip to Sydney.

"We still have all the same meetings and all the same training, just the length of training is a little bit shorter given the recovery time is six days not seven, or nine (days) like the week before," he said.

"We had a light run around on Tuesday, yesterday we had a day off, and today main (training) day and tomorrow is more skills before the game, so things are pretty normal."

As part of the club's preparation, Macmillan said the group would relive some moments from last year's finals exit to the Swans.

"I've got no doubt we'll have a look at a few clips today and just see what they did really well and what we didn't do so well, but in the space of a year a lot of things change," he said.

"And also just the fact that it was a 71-point loss and the fire still burns, so we'll revisit it for sure."

The Roos will also analyse their most recent encounter against the Swans in round 11, when they fought back after half-time to lose by 16 points.

In that game at Etihad Stadium, the Swans kicked away with a five goal to one second quarter to lead by 29 points at the main break.

"We played some really good footy in patches … and we came home and only lost by three goals," Macmillan said.

"It was obviously a disappointing performance given we could only produce three quarters, but you take a lot of positives out of that as well that we were able to match it with them for the large part of the game."
