Nottingham Forest boss Billy Davies has options ahead of the trip to the Liberty Stadium.
The Scot could have a full-strength squad if midfielder Guy Moussi (calf) and striker Robbie Findley (thigh) recover from knocks.
Both players missed the first leg at the City Ground but Davies is hopeful that at least one of them will be fit.
Nathan Tyson looked lively after coming off the bench on Thursday night and he could come into the reckoning for a start.
Fellow forwards David McGoldrick, Garath McCleary and Marcus Tudgay, midfielder Radoslaw Majewski and defender Joel Lynch are also options for Davies.
Forest, beaten by Blackpool at this stage of the play-offs last season, travel to south Wales following a goalless draw in the first leg.
Swansea will only discover on Monday morning whether Neil Taylor will be available for their play-off semi-final second leg against Nottingham Forest after they launched an appeal into his first leg dismissal.
The left-back was sent off just two minutes into Thursday's goalless draw for a high challenge which caught Lewis McGugan on the thigh. An FAW hearing will now take place just hours before the return clash at the Liberty Stadium, with Taylor facing a three-match suspension should the appeal be unsuccessful.
Elsewhere, Swans boss Brendan Rodgers has received a big boost ahead of the decisive sell-out encounter in south Wales.
Influential on-loan Chelsea striker Fabio Borini is expected to be fit having limped off carrying a suspected hamstring injury at the City Ground, with the Italian returning to training on Sunday nursing only slight bruising.
Fellow forward Craig Beattie, who would likely find himself on the bench, has also recovered from a stomach bug which ruled him out of the first leg.
Rodgers must decide whether to restore skipper Garry Monk to the heart of his defence in place of Alan Tate, although much will depend on Taylor's availability, with Tate to switch to full-back should his ban be upheld.
