Joe Ledley is set to miss the FA Cup final against Manchester United with a fracture of the fibula.
The Wales international is also a major doubt to feature at Euro 2016 after suffering a leg injury in the game against Stoke on Saturday.
Ledley was a key figure in Wales’ qualifying campaign but could now miss the showcase tournament which starts next month.
The 29-year-old, who signed for Palace in 2014, has made 30 appearances for the club this season.
Crystal Palace say the midfielder will be continually assessed over the next few weeks by the club’s medical staff.
