Jose Bosingwa has given Chelsea an injury concern after picking up a knock on international duty.
The maurauding full-back picked up a leg injury during Portugal's goalless draw with Sweden on Saturday.
The full extent of the injury is still unclear but Bosingwa has already been ruled out of Wednesday's friendly with South Africa.
"Bosingwa has suffered a gash on his left leg," said Portugal team doctor Henrique Jones.
"He will definitely miss the next game."
Chelsea will be hoping the injury is not too serious and that Bosingwa will be fit for next weekend's trip to Newcastle.
