Loic Remy has returned to parent club Chelsea for treatment on an ankle injury sustained in training, Crystal Palace have confirmed.
Remy signed a season-long loan deal at Palace on August 30 and has yet to make his debut for the club.
Palace confirmed in a statement released on Thursday that Remy is expected to be unavailable for "a number of weeks", while manager Alan Pardew bemoaned the loss of the striker.
"It is obviously a blow for the player and for us as a squad," said Pardew.
"He has just joined us and we were hoping he would play a big part in the team moving forward.
"He was looking great in training and this was an innocuous injury which can sometimes happen unfortunately."
