Former Collingwood squad member Kirk Ugle and ball magnet Adam Faulkner have been recalled by Swan Districts for today's crucial game against West Perth at Steel Blue Oval.
Swans can wrap up a place in the first semifinal tomorrow week by beating the Falcons.
A loss would leave them in danger of being replaced in the top four, with East Fremantle and East Perth also contenders to play in the finals.
Ugle was rested last week with back soreness, while Faulkner was impressive coming back from a foot injury with 26 possessions, 10 marks, three tackles and three inside 50s in the reserves match against East Fremantle.
Coach Greg Harding said Ugle and Faulkner would be valuable inclusions, helping to cover for the loss of Andrew Embley to West Coast for tonight's clash against Adelaide.
Ugle, a third-round draft pick and No.60 overall for Collingwood in the 2010 national draft, played three games in two seasons before being de-listed at the end of last year.
Harding described Ugle as "one of the real success stories".
"From our perspective, Kirk is one of those players who has high impact from sometimes low possessions," Harding said. "His ball use and decision making, especially by foot, is really strong and he's been terrific for us.
"Andrew Embley was in fantastic form for us last week but to have someone like Kirk Ugle to slide back in is a pretty good fit."
Harding said a win today against the Falcons could help set up a home final tomorrow week.
"We think it's pivotal to gain any small advantage we can, especially at finals time," he said.
"To win against West Perth and to win well and secure a home final where we play at Steel Blue in front of home fans could just be the advantage you need."
West Perth, who will play Claremont in the second semi- final tomorrow week, regained ruckman Chris Keunen, midfielders Matt Guadagnin and Jay van Berlo and defender Andrew Strijk after injuries.
East Fremantle had mixed luck with AFL squad members, losing West Coast's Brad Dick (foot), Jacob Brennan (unavailable) and Alex Howson to the Dockers for today's match against St Kilda, while regaining Eagle Brad Sheppard for the must-win clash with ladder leaders Claremont.
Dual premiership players And- rew Foster and Jesse Laurie and midfielder Tom Taylor return for Claremont.Perth picked teenager Joel Kalajzic to make his league debut in the match against South Fremantle at Brownes Stadium.
