Ruckman Tom Hickey will make a shock return from his knee injury as Sydney attempt to rediscover their spark against Geelong at the SCG on Saturday night.
Hickey had been tipped to spend six to eight weeks on the sidelines but instead missed just one game.
"He has been unbelievable, the way he has got back in," Swans coach John Longmire said.
"He's trained well all week.
"He feels good and pulled up well, so it's a great effort."
Sydney have recalled Hickey, Tom McCartin, Dylan Stephens and Colin O'Riordan in place of enforced omissions George Hewett (concussion) and Sam Reid (calf) plus Kaiden Brand and Nick Blakey.
Geelong called up Jordan Clark and Quinton Narkle to replace duo Mark O'Connor (hamstring) and Jake Kolodjashnij (knee).
Callum Mills has implored Sydney to fight pressure with pressure as they seek to win the all-important midfield battle with Geelong.
The Swans earned widespread admiration for their potency during a 4-0 start to the season, which included a 45-point mauling of reigning premiers Richmond.
The prospect of crashing from 4-0 to 4-4 is now in play; Sydney face in-form sides Geelong and Melbourne after losses to GWS and Gold Coast.
Injuries to Lance Franklin, Dane Rampe and other key players have not helped.
Opposition teams have also studied the Swans' free-flowing football from early rounds then successfully stymied it.
"That's what happens. We were obviously performing quite well and people take a close look at you, want to knock you off," in-form midfielder Mills said.
"People have been doing that to Richmond for four years now. They've had a really good ability to match it and go again.
"That's something we're striving to do with a young team.
"We played some bloody good football ... we've got proof of what we can do and everyone believes it."
The Swans won the contested-ball count in the opening four rounds then trailed, both on the final scoreboard and in that key statistic, during their next two matches.
Mills, who has made a productive shift to the middle in 2021, says it is up to the on-ball brigade to set the tone and create a platform for better ball movement.
"Teams have come with a lot more pressure in the last few weeks, they've really hunted us and got after us with pressure," the Swans' academy product said.
"It gets back to winning the ball or if they win it then putting extreme pressure on ... most things really flow on from that.
"Geelong have got a lot of depth in their midfield. They're extremely damaging, so we're going to have to be at our best."
