There aren't many scarier sights for an AFL defender than a fresh, fit and firing Lance Franklin in full flight.

But that's exactly what the GIANTS backline is bracing for as the well-rested Swans superstar ambles to centre half-forward for Saturday's blockbuster elimination final at the SCG.

Come the opening bounce of the sudden-death clash, Franklin will not have played a competitive minute of football in 21 days after missing the Swans' round 23 loss to Hawthorn with a groin problem.

But those last regular-season minutes were some of his best of the year, coming as the recently-crowned All Australian captain booted five goals to lay waste to the GIANTS' top-four aspirations.

With the 20-point defeat still front of mind, high-flying intercept defender Nick Haynes is well aware the GIANTS will be getting a far less banged-up version of Franklin this time around.

"He's a superstar of the game and has had another wonderful year," Haynes told AAP.

"He'll have two weeks off to freshen up and he's going to come out firing."

GIANTS skipper Phil Davis is the probable first-choice option, even though Franklin got off the leash in the second half during their last head-to-head tussle as the defender dealt with a corked hip.

But Davis will be rejuvenated, too, and this time defensive reinforcements Aiden Corr, Sam Taylor and Zac Williams are putting their hand up for a recall from injury to help their captain.

Key back Adam Tomlinson, one of five GIANTS along with Haynes to feature in every game this season, has welcomed the group's impending return.

"We do have the chance to get a few key defenders back," the 25-year-old said.

"But at the same time, Phil does a terrific job every time he plays on Buddy.

"He's probably got one of the best records in the competition on him."
