Paris St Germain laboured to a 1-1 draw at home to Ajaccio - but the game was interrupted in the second half after a terrible clash of heads between Blaise Matuidi and Joshua Nadeau.
The two players collided in sickening fashion in the 67th minute of the Ligue 1 encounter - with Matuidi coming off much worse.
The France international was immediately substituted, and required stitches and a visit to the hospital. He will undergo additional tests as PSG look to determine the severity of the injury.
It was a nasty clash between two players both with eyes only for the ball. The game resumed with Ajaccio 1-0 ahead courtesy of Benoit Pedretti's ninth minute curler into the top corner.
And the Corsican side nearly held on for a famous win at the Parc des Princes, only for Edinson Cavani to deliver the goods late on - smashing home a superb equaliser with less than five minutes remaining.
PSG had several chances in stoppage time - Marco Verratti squandered the best - but Ajaccio clung on for a point thanks to a stunning performance from their Mexican international keeper Guillermo Ochoa.
That's another two points dropped by Laurent Blanc's PSG team - they have just two points after two games as they look to defend their Ligue 1 title.
