Arsenal boss Mikel Arteta has provided an update on the fitness of Riccardo Calafiori ahead of the clash with PSG.
The Italian defender started his second match for the club as Arsenal continued their unbeaten start to the season with a 4-2 win over Leicester.
The Gunners required two stoppage-time goals to seal the victory after the visitors had come from behind to equalise.
Calafiori landed awkwardly after competing for a header with Odsonne Edouard just seconds before the end and he was spotted in tears and wearing a knee brace after the match.
However, Arteta says the £42m signing from Bologna and Ben White, who missed the win over the Foxes with an injury, could both bit fit to face PSG pending further tests.

'Those are the two players in contention and we have to review today', Arteta said in his pre-match press conference.
On Calafiori, he added: 'We didn't have a. training session yesterday. Obviously he was a bit emotional after the game and let's see how he is today.'
Calafiori has shone since his summer move and scored in the fiery 2-2 draw with Manchester City last week.
Arsenal will seek to pick up their first Champions League win this season when they host the French champions at the Emirates and Arteta is embracing the challenge.
'Everybody is looking forward to it,' he said. 'The group stage is a bit different this season and the opposition we are going to face tomorrow is probably at the highest level that you can face in European football.
'But it's a good opportunity for us to see how we deal with these nights, how prepared we are and how we can impose ourselves in this kind of context.
'PSG are exceptional and they dominate every phase of play. They have a very clear intention of how they want to dominate the game through the ball and when they don't have it, they want it straight back. They are really aggressive with it and they confront you.
'Of course, we want to win the game and we know after the draw in Atalanta, with the number of games we have left still, it's going to be really important. Nothing is going to be decided tomorrow.'
