Rangers and Algeria defender Madjid Bougherra has been told to rest for up to 10 days as he struggles with his fitness ahead of the World Cup finals.
The 27-year-old missed the Scottish champions' final four games and arrived at Algeria's current training camp with a torn calf muscle.
National coach Rabah Saadane now wants the centre-half to rest for up to 10 days, meaning he will miss next week's friendly with the Republic of Ireland in Dublin.
Saadane said: "Madjid will be subject to intensive medical care.
"He came to this training camp with a torn calf and now our medical people will treat him in the best possible way to make sure he is fit in time for the finals.
"Madjid's injury requires special care and I want him to rest for up to 10 days."
Algeria will take on England, the United States and Slovenia in Group C and are 12/1 outsiders with Sky Bet to win the group.
But Bougherra insists the side are not afraid of anyone, telling Rangers News: "England are one of the favourites for the World Cup title but, after that, we have nothing to lose.
"The USA and Slovenia have a lot of experience but we are going to South Africa with high hopes.
"We are going to go out on the pitch, enjoy ourselves and give everything for our country because we think we can do something special.
"Our big strength is our unity. We all want to succeed for Algeria because we all love our country and we will all work very hard together.
"It will be tough for us at the World Cup because every side there is good - but we are not afraid of anyone."
