Kylian Mbappe could yet feature against Lyon on Sunday having already returned to Paris Saint-Germain training following his midweek injury.
Having created PSG's goal in a 1-1 draw at Club Brugge, Mbappe hobbled off on Wednesday with an ankle issue.
Any lay-off would have represented a blow to Mauricio Pochettino, with five matches before the October international break – starting against Lyon and including a Champions League encounter with Manchester City.
Mbappe has been involved in seven goals in all competitions so far this season – the most of any PSG player and joint-sixth across Europe's top five leagues.
The World Cup winner also has a fine record in matches with Lyon, with his eight goals against them in Ligue 1 his most versus any side currently in the division.
But Mbappe could still improve that tally further on Sunday, with PSG reporting "good evolution" of his injury on Saturday.
And Pochettino added in a news conference: "Kylian trained with the group this morning. We'll see how he is tomorrow morning to see if he's part of the group."
With this frantic period of the campaign not aided by a hectic international break for many of his players, Pochettino said PSG would "try to use all our players while striking the right balance".
That could mean a debut for Nuno Mendes, but the PSG coach still has "no date or specific information" on Sergio Ramos' return to fitness.
Meanwhile, Lionel Messi is set for his home bow.
"Leo is calm," Pochettino said. "He knows he can make his debut in front of his fans.
"The team is focused on the game and improving on our Champions League performance and winning the game of course."
Mbappe, Messi and Neymar started together for the first time at Brugge, but none of them were on the scoresheet, with the Argentina great waiting on his maiden PSG goal.
"Players need time, to know each other, to find affinities," Pochettino added. "It will happen with time. We have a very talented squad."
Plenty will be expected this weekend, with Lyon's 1-0 win at the Parc des Princes last December their first victory in 13 league visits.
