Spanish striker Michu will be absent from the Swansea squad for Saturday's Premier League clash against Liberty Stadium visitors Aston Villa.
Michu has endured an injury-ravaged season due to persistent ankle trouble, and he is now suffering from ankle swelling that is requiring medical attention.
Defender Chico Flores is again ruled out by suspension following his sending-off in the 1-0 defeat against Chelsea 12 days ago, with Jordi Amat set to deputise.
Swansea go into the Villa game six points clear of relegation danger with three games left.
Defender Joe Bennett is the only fresh injury concern for Aston Villa ahead of Saturday's Barclays Premier League trip to Swansea.
Bennett is a doubt for the game at the Liberty Stadium after picking up an ankle problem in training this week.
Villa already have the likes of Christian Benteke, Libor Kozak, Charles N'Zogbia, Jores Okore and Gary Gardner out of action, while it remains to be seen whether or not striker Nicklas Helenius returns to the matchday squad after his thigh injury.
Swansea squad: Vorm, Amat, Taylor, Williams, Britton, Bony, Hernandez, Dyer, Shelvey, Cornell, Lamah, Routledge, Tiendalli, De Guzman, Canas, Rangel, Pozuelo, Tremmel, Vazquez, Richards, Ngog, Emnes.
Aston Villa squad: Guzan, Steer, Clark, Baker, Luna, Vlaar, Bennett, Lowton, Bertrand, Bacuna, Albrighton, El Ahmadi, Westwood, Delph, Sylla, Tonev, Holt, Weimann, Agbonlahor, Robinson.
