Chico Flores could miss Sunday's encounter with a knee problem, while Michel Vorm, Angel Rangel and Leon Britton are all doubts to face Chris Hughton's side
Michael Laudrup's men have been unable to build on their 3-0 victory over Newcastle on December 4, drawing at home to Hull before losing at St Gallen in the Europa League on Thursday.
Swansea have injury worries that were only added to by the trip to Switzerland, with centre-back Chico Flores hurting his knee.
The Spaniard may be joining the likes of goalkeeper Michel Vorm, Angel Rangel and Leon Britton on the sidelines.
Flores was suspended for the Norwich clash regardless of his injury, but his absence may hurt during the busy Christmas-New Year period.

|6/1||Michu is 6/1 with BetVictor to open the scoring against Norwich City|
Michu (ankle) returned in Swansea's 1-1 draw against Hull on December 9, but was rested for the meeting with St Gallen.
He is almost a certainty to start for a Swansea side who have won just two of their past 11 matches in all competitions.
Since both returned to the English Premier League, Norwich have enjoyed an edge over Swansea.
In their past four meetings, Norwich have claimed three victories and the most recent match – in April – finished in a 2-2 draw.
Expect plenty of goals with the teams having shared 20 in their past four meetings, including a 4-3 thriller in December last year.
Norwich have been inconsistent, but at least have improved since being hammered 7-0 by Manchester City in November.
Chris Hughton's side have won win-loss-win-loss-win since then, moving four points clear of the relegation zone.
Norwich have injury concerns of their own with Anthony Pilkington (hamstring) and Robert Snodgrass (knee) among those missing.
Elliott Bennett (knee), Mark Bunn and Alexander Tettey (both ankles) are also battling to be fit, while Ricky van Wolfswinkel could return after recovering from a toe injury.
The biggest problem for Hughton's team has been their defence – somewhat skewed by the seven-goal loss at City – conceding 28 goals in 15 league games.
They have managed two clean sheets in their past three outings, and that may be required to take something against Swansea.
