Neymar was carried off on a stretcher deep as Paris Saint-Germain lost 1-0 at home to Lyon to drop to third place in the French league.
Neymar cried out in pain after suffering a left ankle injury in the seventh minute of injury time at Parc des Princes following a heavy tackle from Thiago Mendes, who was then red carded.
“No news about Ney(mar),” PSG coach Thomas Tuchel said after the game. “He’s with the physio and the doctors, and he will have some tests tomorrow.”
Lyon held on for 10 minutes of stoppage time to extend their unbeaten run to 11 games and throw the title race wide open.
PSG's fourth defeat of the season sent Lille top after they beat Bordeaux 2-1. Lyon are second on goal difference, while PSG are one point behind in third spot.
“We were never ready to play this game. The team was very tired mentally, we made a lot of mistakes and didn’t play with enough rhythm and confidence," a dejected Tuchel said. “We did not concentrate enough. It’s a step backwards. I’m surprised, I was expecting a lot more.”
PSG were without captain and centre half Marquinhos because of a hip problem and he was missed against Lyon's slick attacking trio of Memphis Depay, Karl Toko Ekambi and Tino Kadewere.
They have now combined for 18 goals and nine assists in 14 games, with Toko Ekambi setting up Kadewere to rifle a shot past goalkeeper Keylor Navas in the 34th minute after PSG's defence carelessly gave the ball away under no pressure.
“I think we could have won by more. We had a penalty for Depay which was totally ignored," Lille coach Rudi Garcia said.
“The league is very tight and we did well to win tonight, so we can keep looking ahead.”
