The Sydney Swans head into the fourth derby, and the first at the SCG, in solid form following wins over Carlton and Melbourne. The premiers know they need to keep winning if they are to stay in the hunt for the top four. But they have plenty of injury worries, with Sam Reid tearing his quad for a second time against the Demons, adding his name to a list that includes Adam Goodes, Lewis Jetta, Rhyce Shaw and Lewis Roberts-Thomson.

Their cross-town rivals are still searching for their first victory of 2013. GWS was extremely competitive against the Western Bulldogs in Canberra last weekend, leading at every change before succumbing by just four points. They will also be buoyed by their previous clash with the Swans, when they overcame a poor start to get in front in the second term before ultimately falling short by 30 points.
