Paris - Paris Saint-Germain's German defender Thilo Kehrer has been ruled out for up to three weeks with a foot injury, the French champions said on Monday.

Kehrer, 22, who has made seven international appearances, was replaced after 76 minutes of PSG's 3-0 Ligue 1 victory over Nimes on Sunday.

"The medical staff will evaluate more precisely how long he will be sidelined depending on how the injury heals, currently estimated at 15 to 21 days," the club said on their website.

The left-back, in his second season at the Parc des Princes, joins Spanish midfielder Ander Herrera on Thomas Tuchel's injury list.

PSG travel to Rennes on Sunday for their second league game of the campaign.
