Wilfried Zaha has returned to Crystal Palace for assessment after sustaining a thigh injury while on international duty with Cote d’Ivoire.
The 25-year-old was on parade in the Elephants’ 4-0 thrashing of Central African Republic on Friday but missed Tuesday's reverse fixture which ended in a goalless draw in Bangui.
The injury is reportedly related to his abductor muscle – the same one that forced him out of his side's 2-0 loss against Southampton in September.
Zaha has scored three goals in seven Premier League games this season.
Palace yet to win a match without the 25-year-old since they won 3-2 at Sunderland in September 2016 and the injury comes as a huge blow for the Selhurst Park outfit who also have Christian Benteke set for a knee surgery that rules him out until 2019.
The Eagles, placed 14th in the log, will hope to bounce back to winning ways against Everton on Sunday after back-to-back losses to Bournemouth and Wolverhampton Wanderers in their last Premier League outings before the international break.
