Paris Saint-Germain midfielder Javier Pastore is facing up to a month out owing to a torn hamstring.
PSG says on its website on Wednesday that tests concluded Pastore needs a ''minimum of three to four weeks of treatment.''
The Argentina international limped off clutching his thigh during the first half of the French Cup match against amateur side Sable FC last Friday.
PSG paid a French-record ?42 million ($60 million) to sign Pastore from Palermo last August. He has scored 10 goals this season.
