Arsenal will be without Dani Ceballos for Saturday evening's Premier League clash with Leicester City.
Head coach Unai Emery delivered an injury update on the on-loan Real Madrid star ahead of the trip to the King Power.
The Spanish midfielder picked up what appeared to be a hamstring problem during the Gunners' 1-1 draw against Vitoria in the Europa League.
The incident occurred in the second half when Ceballos pulled up and attempted carry on playing, but it soon became clear that he could not, with Emery forced into a change as Ceballos went straight down the tunnel after being substituted, and extent of the injury has now been revealed.
"Good evening, [Dani] Ceballos has a small injury and he is going to be out for tomorrow.
“The rest of the squad, I think they are ready for tomorrow.” Emery said in his press conference.
Ceballos' injury does open up a spot in midfield which will need to be filled at the King Power.
However, Emery confirmed that former captain Granit Xhaka, who hasn't featured since his gesture towards the Arsenal fans in the 2-2 draw against Crystal Palace, will not play.
"Not yet. I spoke with him on Tuesday for how he is feeling now and his mind because he is training well but he said to me he can’t play.
“We are going to wait.”
