Dane Rampe is set to miss Sydney's AFL showdown with Geelong's star-studded forward line but the Swans are upbeat that fellow key defender Tom McCartin will return from injury.
Sydney have suffered losses to Greater Western Sydney and Gold Coast since a sparkling 4-0 start.
Curbing the influence of Coleman medallists Tom Hawkins and Jeremy Cameron will be key to the Swans' hopes of recording an upset at the SCG on Saturday night.
Hawkins and Cameron led the Cats to a 97-point win over West Coast in round six, when they shared a forward line for the first time.
Rampe is expected to miss this weekend's clash as he continues to recover from a broken finger, while fellow defender George Hewett and key forward Sam Reid will be enforced omissions.
But co-captain Josh Kennedy predicts that McCartin, who skipped the loss to the Suns because of a tight hamstring, and Nick Blakey, who suffered a corked thigh in round six, will face the Cats.
"Tom will come back in and go up against a pretty dynamic forward line," Kennedy told reporters prior to the Swans' closed training session.
"He (Blakey) will come out and fully train today, he'll be right to go.
"It is certainly frustrating (when injuries occur), we were coming into the season really healthy.
"But it's part of the game ... not an excuse.
"We feel like we've got some really good depth."
Kennedy was impressed with Hawkins and Cameron's connection but highlighted how former teammate Gary Rohan and other Geelong players proved potent threats.
"They've got some real power up there and their small forwards can do a bit of damage. Gazza kicked three goals last week," Kennedy said.
"They (Sydney's defenders) are going to have to be on their toes.
"We're going to have to do our best to make sure the entries going into their forward line are as sloppy as possible, limit the numbers as much as we can to help them out.
"Same as every week, it'll take a whole 22 to help out."
Kennedy highlighted the Swans' dip in pressure and contested-ball numbers as the most glaring issue they must fix.
"It's a real strength of Geelong's too," the midfield star said.
"For us to get back to where we were in the first few rounds, it's certainly not just a few guys who need to pull their weight.
"Everyone can look to improve that one to five per cent."
