Both Gary Cahill and Scott Dann face late fitness tests before Crystal Palace travel to Watford this weekend as they look to make it three wins in a row.
Both defenders have been suffering from ankle injuries and are doubts for this weekend. Manager Roy Hodgson has refused to rule the pair out but says he still cannot be sure whether they will be available.
After Mamadou Sakho was shown a straight red card just 19 minutes into Tuesday's 1-0 win over Bournemouth, and with Martin Kelly covering the injured Joel Ward at right back, Cheikhou Kouyate dropped in alongside James Tomkins in the centre of defence.
The former West Ham midfielder has experience playing at the back and could well reprise that role at Vicarage Road.
With Patrick van Aanholt having suffered a hamstring strain, Jeffrey Schlupp, who has two goals in as many games, is set to fill in at left-back.
Possible Crystal Palace XI: Guaita; Kelly, Tomkins, Kouyate, Schlupp; Milivojevic, McArthur, McCarthy; Townsend, Zaha, Ayew
