GREATER Western Sydney has a chance to make a giant move on the ladder when it takes on cellar-dweller Adelaide from 5.10pm ACST today.

The game at Adelaide Oval is the first of a Tuesday night double-header, and will be followed by the Carlton and Sydney clash at Metricon Stadium from 8.10pm AEST.

The Giants made a late change for the clash with Jackson Hately replacing Zac Langdon (illness).

After Melbourne stumbled against Fremantle on Monday night, the door has opened for the Giants who can overtake Collingwood and jump into seventh spot to be on equal points with sixth-placed St Kilda.

A win would also give GWS a one-game buffer on the ninth-placed Bulldogs and a two-game buffer on the sputtering Demons, the latter now in tenth.

With games against Melbourne and St Kilda to come, the Giants' destiny is entirely in their hands.

LADDER PREDICTOR Can your team make the eight?

After its last round heroics, Adelaide is determined to continue its momentum and claim a second scalp before the season is out.

The Crows registered their first win of the year in round 15, when they dismantled the Hawks to the tune of 35 points to give new coach Matthew Nicks a taste of victory in 2020. 

At the conclusion of this game, we then head to Metricon where Sydney and Carlton will do battle.

The contest is set too be an intriguing one, with the Blues out to make amends for it recent fade-outs that have all but cost them a shot of finals.

Carlton just couldn't seal the deal against GWS in round 15, despite leading at three-quarter time. And it was a similar story in the round before, when the Blues were overrun by Collingwood in the final term.

The Swans are keen to finish the season strongly after comfortably defeating Melbourne in their last encounter.

They will take an unchanged line-up into the game, but the Blues will be without veteran star Eddie Betts in one of four changes. 

Former No.3 pick Paddy Dow has been dropped alongside Cam Polson, while ruckman Marc Pittonet will join Betts in being managed off the five-day break.

The Blues will debut former basketballer Matt Owies, Tom De Koning will return to carry the ruck duties and Lachie Plowman (back) and David Cuningham (calf) have been cleared to play from injuries.
