If the Argentine is not fit, Lewis Price will again deputise, while Alex Marrow is back after five games out.
Cardiff striker Michael Chopra is set to be fit despite picking up a late ankle knock against Ipswich.
Dave Jones is likely to field the same side despite that result, as Paul Quinn and Seyi Olofinjana remain sidelined.
MATCH PREVIEW
Crystal Palace have been under the stewardship of legendary former player Dougie Freedman for 11 matches now (two as caretaker boss). The Scot has led his team to three victories during this time, with all of them have coming against sides within the bottom five of the league table.
Fans of fourth-bottom Palace realise the importance of beating fellow relegation candidates, but are also desperate for the Eagles to show continued signs of improvement with a victory over the division's more stable clubs. They are without a win against a side from the top half of the table since early November, and kick-off only a point above the relegation zone after Saturday's defeat at Burnley.
High-flying Cardiff were also beaten at the weekend but remain well within the hunt for an automatic promotion place. This campaign is the club's eighth consecutive at this level, and the Bluebirds have improved their league position every season bar one.
The man who guided Cardiff to promotion to the Championship via the play-offs in 2003 was Lennie Lawrence, who these days he can be found in the Crystal Palace dug-out as assistant to Freedman. Lawrence, who took charge of over 1,000 league matches during a 27-year managerial career, left the Bluebirds in May 2005 after helping to establish them in this division.
