Belgium are likely to be without Zakaria Bakkali for this summer's European Championships in France.
Valencia confirmed earlier today that the winger had undergone surgery on a hip injury, which could keep him sidelined for four months.
"The player, accompanied in Belgium by the chief of the medical staff, Dr Albors, was operated on on Monday," read a statement on the club's official website.
"After the procedure, which was completed normally, the player will begin a period of recovery estimated to be three to four months."
The Championships are due to get underway on June 10.
