Dembele was replaced by Bradley Barcola in the 70th minute after pulling up with what appeared to be a hamstring injury. On Thursday, he was absent from training and is likely to miss PSG's upcoming match against Strasbourg on Saturday.
PSG has provided an update on Dembele's fitness, which could be concerning for Arsenal ahead of their Champions League semi-final second leg next week.
The medical report stated, "Ousmane Dembele has strained his right hamstring. His condition is progressing well. A further assessment will be carried out shortly."
