The Ligue 1 leaders have confirmed that the Brazilian fractured a bone in his cheek in Friday’s 1-0 win over Lorient.
The injury does not require surgery, meaning the 29-year-old will not miss the French outfit’s upcoming Champions League quarter-final tie with Chelsea.
Thiago Silva was forced off during the first half of the game after taking a blow to his face while jumping to head the ball.
It was initially feared that the centre-half could be facing a lengthy spell on the sidelines.
Such a scenario would not have been ideal for the Brazil captain with a Champions League quarter-final tie with Chelsea around the corner and a World Cup less than three months away.
However, PSG confirmed on Saturday that the injury did not warrant an operation.
“Examinations on Thiago Silva performed so far have revealed a fractured of the left zygomatic bone,” read a club statement.
“His condition did not require surgery. Downtime will depend on the evolution of pain in the coming days.”
“His participation in the quarter-finals of the Champions League should not be compromised.”
PSG host Chelsea at the Parc des Princes on April 2 before travelling to Stamford Bridge for the second leg six days later.
