Teammate Jude Bolton, who confirmed his retirement on Monday, remains confident the premiers can bounce back from their dip in form and growing injury list to still be a major player in September.
But the Swans were comfortably cast aside by Geelong on Saturday, which came two weeks after another disappointing loss to Collingwood at ANZ Stadium, and they now have another injury concern.
Adam Goodes (knee) is looking long odds to return this season, while coach John Longmire had a mixed report on the club's other worries, including Lewis Jetta (shin), Sam Reid (quad) and Lewis Roberts-Thomson (knee).
"Daniel Hannebery probably won't play," Longmire said of this week's Grand Final re-match at ANZ Stadium.
"He's got a bit of a knock to his knee, so he probably won't play this week.
"We'll look at obviously getting Jude back. Lewis Jetta and Lewis Roberts-Thomson we'll discuss as the week progresses.
"They may be playing this weekend. Sam Reid probably won't."
Jetta hasn't played since round 10, while Roberts-Thomson has been missing since round four, so lining up in the reserves' NEAFL final this Saturday may be the duo's best option if they prove their fitness at training.
Bolton, who will return from one week on the sideline with illness this Friday night, feels the Swans can bounce back and again be a major player in the finals.
The Swans lost three of their final four games heading into last year's finals series before sweeping all three matches in September to secure the premiership.
"It's obviously been a couple of setbacks, the way we played against Collingwood and also Geelong on the weekend was disappointing," Bolton said.
"We've got plenty to work on and it's probably a positive in a sense.
"The media have probably written us off for this year, but internally we've just got to keep confident, keep working on a few things, we've got to train as hard as anyone and we've got the double chance as well.
"It's really exciting and it's the best time of year.
"It's a whole new season."
Bolton, who is contemplating roles in the media and is also an accredited player agent, joked he wished he was announcing "a four-year deal to see me through to 400 games" instead of his impending retirement.
But he believes the club is in great hands.
"I've loved playing along some of these young guys as well," he said after expressing his gratitude at the opportunity of playing alongside talent such as Tony Lockett, Paul Kelly, Adam Goodes and Brett Kirk.
"I think we've got some of the best young talent in the League at the moment.
"We want to bounce back this week."
