Arsenal have been hit with another injury scare on top of an already dire striker shortage after Gabriel Martinelli was seen limping out of training on Wednesday.
The Brazilian, who is one of the Gunners's few available attacking options, was spotted making his way off the pitch at the Emirates and down the tunnel during an open training session.
It could be a further blow to Mikel Arteta's side who currently have no fit recognised strikers ahead of their final two Premier League fixtures.
Martinelli later returned to the pitch and took part in the remainder of the session.
