Crystal Palace star Michael Olise has suffered another hamstring injury this week.
The winger, who signed a new deal at Palace in the summer after interest from Chelsea, will not be available for a long time.
Per Evening Standard, Palace are not putting any timetable on his return as yet.
The news is a huge blow to manager Roy Hodsgon, who also lost forward Wilfried Zaha this summer.
The 21-year-old Olise is one who Palace want to protect, as they know his quality when he is fully fit.
Olise had been expected to return in the coming weeks, but it appears that his injury has resurfaced.
