Arsenal striker Gabriel Jesus missed training ahead of their Europa League game against Bodo/Glimt.
The Gunners are set to take on the European minnows on the back of an impressive win over Liverpool in the Premier League at the weekend.
Manager Mikel Arteta stated that Jesus may not travel with the team.
Speaking after the Liverpool match, he told reporters: “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; I don't know actually what happened, but we'll assess how well he is."
Per football.london, either Eddie Nketiah or young Spanish teenager Khayon Edwards may get a chance to impress up front.
