Arsenal striker Gabriel Jesus has missed training ahead of his side's Europa League clash with Bodo/Glimt on Thursday night.
It comes after he picked up a head injury against Liverpool on Sunday and had to be treated on the pitch, following a collision with Kostas Tsimikas' elbow.
The Brazil international did not suffer a concussion and was able to continue briefly, but was later replaced by Eddie Nketiah in the Gunners' 3-2 win.
When asked about the injury after the game, Arsenal boss Mikel Arteta said: ‘I don’t know, I haven’t been with the doctor yet, I’m sure they are checking him, he seemed OK after the game.
