Palace have been in free-fall since the turn of the year, having failed to pick up a positive result in the league since their 2-1 win away at Stoke City on December 20.
Their torrid domestic form has seen them sink from a European qualification spot to 16th spot in the standings, with the club now in danger of entering a relegation fight with fellow strugglers Norwich, Sunderland and Newcastle.
Manager Alan Pardew has found reprieve in the FA Cup this term, with his south London side still battling for the famous trophy as one of the four teams left in the competition.
Ledley has made just 10 league starts this year - stark contrast to his ever-presence in 2014-15 - due to Pardew’s continued midfield rotation at Selhurst Park.
The tough-tackling midfielder has a trip to France for the European Championship to look forward to this summer with Wales. However, for now, the 29-year-old says he is focused on club matters.
“I know I have the Euros coming up but for now I am just concentrating on keeping Palace safe and in the Premier League,” he is quoted as saying in the Daily Express.
“We are not safe yet but I am confident we will be.
"We believe in what we are doing and we need that one win, that is all it would take to make sure of things."
