The confirmation came from the Egyptian Football Association (EFA) as he was playing for Egypt and this could lead to him missing some upcoming games.
The Arsenal midfielder is however asymptomatic and not suffering from any weakness yet – he should recover soon.
Aubameyang earlier had spoken about Elneny being back from loan and how he has impressed since he got back from Besiktas.
“It was also a fantastic performance in midfield from Mo,” he said. “I think his loan spell was good for him – to go out and get some more experience. He came back with that experience and that’s really important too. How he’s been playing since he came back is just unbelievable.
“His sprint at the end of the game… I don’t know how he did that! That is the energy he has, that’s what we want as a team and everyone here really wants to play that way. We want to give everything, in every minute and that’s exactly what Mo is doing.
“He’s a funny guy Mo, and I think we are similar people. We are both always smiling and being positive, so when we get together it’s always funny – we laugh a lot. It’s really, really nice to be around him.”
