Paris Saint-Germain surrendered top spot in Ligue 1 after losing 1-0 at home to Lyon on Sunday but potentially suffered a more devastating blow as an anguished Neymar was stretchered off with an apparent ankle injury.

Tino Kadewere's first-half goal secured Lyon a seventh win in eight matches as they moved level with Lille, who took over first place earlier in the day following a 2-1 home victory over Bordeaux.

PSG dropped to third after losing for the fourth time in 14 games this season, but the far greater concern will be the health of Neymar after his ankle appeared to twist awkwardly under a challenge from Thiago Mendes in stoppage time.

The Lyon midfielder was sent off for the tackle following a VAR review while a distraught Neymar, in considerable pain, was taken off on a stretcher having immediately signalled for medical assistance.

"He's with the physio and the doctors and we have to wait for the tests tomorrow (Monday)," PSG coach Thomas Tuchel told French broadcaster Telefoot.

Lyon's first win away to PSG since October 2007, the last season they won the Ligue 1 crown, provided fresh hope of a genuine title race this term with the top five teams separated by just three points.

With Kylian Mbappe rested from the start, Moise Kean partnered Neymar in attack following the Brazilian's hat-trick in the midweek 5-1 Champions League win against Istanbul Basaksehir -- a game that was completed 24 hours later than planned after an unprecedented anti-racism protest.

However it was Lyon, without any European commitments this season, who took the lead on 35 minutes after a loose pass under pressure from PSG captain Presnel Kimpembe.

Karl Toko Ekambi collected the ball in the PSG half and immediately picked out Kadewere who steadied himself before sliding low beyond Keylor Navas for the Zimbabwe international's fifth goal of the campaign.

Alessandro Florenzi drew a sharp save from Anthony Lopes before half-time while a thumping effort from Lucas Paqueta called Navas into action midway through the second half, just after the introduction of Mbappe.

After Navas kept out an attempt from Lyon substitute Bruno Guimaraes, Mbappe had a late chance to rescue a point for PSG but shot wide from the edge of the area in time added on before Neymar's unwelcome injury.

Portugal defender Jose Fonte, who turns 37 later this month, scored the winner with a bullet header for Lille against Bordeaux.

Jonathan Bamba's exquisite curling strike gave Lille the lead on 16 minutes at the Stade Pierre-Mauroy before Toma Basic levelled from a Hatem Ben Arfa corner.

Lille travel to bottom side Dijon in midweek before the visit of defending champions PSG next Sunday in what could be a defining week in terms of a competitive title race this season.

"I don't think we can fight with Paris for the title. We need to fight to pick up points and stay at the top," said Lille coach Christophe Galtier.
