The hope will be Koscielny can come through that and then take his place in the defence at St Mary's, with Konstantinos Mavropanos and Rob Holding injured, Shkodran Mustafi struggling with a hamstring problem and Sokratis Papastathopoulos suspended.
The Arsenal boss also confirmed that Mesut Ozil will be back in the squad on Thursday night after recovering from a back injury that's kept him out for the last four games, but the boss hasn't decided whether to start him or bring him off the bench.
We have some players with injuries and unavailable at centre-back.
"We are going to decide but the first is to think about the match tomorrow because we need to receive information on how he can feel".
Emery is unsure about whether Koscielny will be able to handle the workload well enough to feature again against Southampton in the Premier League on Sunday and will wait to see how he copes with the visit of Qarabag.
"After his injuries, he is OK", said Emery.

Most of the damage was on the home's first floor, leading investigators to believe that's where the fire started, Wright said. Firefighters say the woman jumped from a second-floor window and was the only survivor of the blaze in Youngstown.
"It hurts to talk about it, it hurts to think about it, but that's why I think it's so important that we need to get rid of it in the game".
Arsenal won the reverse fixture against Qarabag 3-0 on matchday two, scoring with three of their four shots on target.
"Tomorrow is a good day for a lot of players - in the group we are first but we want to win, and also with a good performance".
We can use other players in this position, like sometimes Monreal and Lichsteiner.
"We achieved our Europa League objective, so we are going to use some different players with also players coming from the under-23 team".
"We are going to decide after tomorrow's match, as it's the first match with us that Laurent Koscielny will play". There are starts for Joe Willock, Bukayo Saka, Ainsley Maitland-Niles, Carl Jenkinson and Eddie Nketiah.
