Sydney coach John Longmire is confident Shane Mumford is on track to return from a knee injury in time for Sunday's crucial clash against Carlton at Etihad Stadium.
The star ruckman suffered knee bone bruising against St Kilda eight days ago and sat out Saturday night's big win over Gold Coast.
Mumford's return would be a major boost for the ladder leaders following an injury to key forward Sam Reid, who is sidelined for two to three weeks with a medial ligament tear suffered against the Suns.
"At this stage we plan on training him on Friday fully to be able to say he's okay to play," Longmire said of Mumford on Monday.
"We're hopeful that he can get through and we'll name him in the squad."
"He actually ran on Friday up in Queensland ... he pulled up pretty well from that and ran again today and was ok.
"If Mummy trains the rest of the week and pulls up well, obviously he'll come straight back into the team.
"I thought before his injury he was starting to hit some really good form so the good thing is that hopefully he only misses the week and he's able to perform straight away."
Longmire concedes Reid's loss is a blow but is confident Adam Goodes and makeshift forward Lewis Roberts-Thomson can fill the void in the forward line with help from Mumford and fellow ruckman Mike Pyke.
Goodes will have a light week on the training track after copping a corked thigh but is expected to play.
"We don't expect him to do much training on Wednesday, he's feeling a lot better today and we expect him to train fully on Friday and play, we think he'll be fine," the coach said.
"With Mumford coming back in that gives us the flexibility to still be able to use Goodesy in a couple of different roles and that may be on-ball as times.
"But Goodesy on the weekend kicked three goals and contributed probably to four or five other scoring shots for us.
"He's so dangerous to match up on in that part of the ground that the majority of the time we expect him to play forward with bursts on-ball."
The Swans sit four points clear of Adelaide, Hawthorn and Collingwood on the AFL ladder, but Longmire is taking nothing for granted ahead of the Carlton clash.
"We know that form can change really quickly and we don't take anything for granted in this competition because it's so hard," he said.
"Carlton have won three of the last four so their form's been really good."They're obviously desperate to stay in the fight for the eight so they'll be really fierce this week and they might get a few players back who didn't play on the weekend as well so we expect them to have a really strong team."
