Hamraoui thus misses Saturday's return match against Lyon, who won the first Champions League semi-final 3-2.
The 32-year-old is said to have got into a fight with teammate Sandy Baltimore last Saturday, writes AFP, which meant that she was poked for Sunday's first CL match.
And on Tuesday, PSG decided to shut down Hamraoui all week.
According to the newspaper Le Parisien, it is for it to be calm in the squad before the return meeting with Lyon.
The club also spoke to those involved in the brawl at the training, in addition to Baltimore also Kadidiatou Diani and Marie-Antoinette Katoto.
According to Le Parisien, this week's suspension is a first step towards getting rid of Kheira Hamraoui due to the explosive atmosphere in the squad, where the players no longer talk to each other and where heated quarrels occasionally occur.
In November, Hamraoui was beaten by two masked men who pulled her out of the car she was traveling in. Teammate Aminata Diallo was accused of being behind the beating.
There must also have been an incident between Hamraoui and Katoto after a league match in Montpellier.
