Mauro Icardi suffers from a sprained right shoulder and will be out for three to four weeks, PSG said.
The tests confirmed that the Argentine forward "suffers from a grade 2 sprain of the right acromioclavicular. The return to collective training is estimated between three and four weeks".
Icardi was injured at the end of the race last Friday, during the 4-2 victory in Brest.
For him, therefore, no match with Reims on Sunday, but the call-up with Argentina in early September is also at risk.
Possible date of return for the first of PSG in the Champions League, 14 or 15 September.
