Ceballos initially pulled up early in the second half of the 1-1 draw before he was replaced by Matteo Guendouzi in the 54th minute.
Arsenal boss Unai Emery has revealed that Dani Ceballos has sustained "small" hamstring injury.
The Spaniard who was signed on loan from Real Madrid during the summer, got injured in the Gunners’ Europa League draw with Vitoria SC on Thursday evening.
The midfielder initially pulled up early in the second half of the 1-1 draw before he was replaced by Matteo Guendouzi in the 54th minute.
Arsenal have not confirmed whether Ceballos will miss Saturday's Premier League trip to Leicester City as he is to have further tests.
"We are going to wait for the analysis tomorrow but, at the beginning, I think it’s a small injury," Emery told a news conference as BBC Sport quoted.
Arsenal were close to claiming a win today after Shkodran Mustafi headed in Nicolas Pepe's free-kick in the 80th minute, but Bruno Duarte equalised in injury time as both sides shared the spoils.
Following the match, Emery told Bt Sport: "The players worked and tried and we were very close to winning. In the last minute, they pushed a lot and they scored.
"The objective is to be first in the group and we are. At the end of the match, we're thinking about Saturday and Leicester.
"We tried [to score] but also they are a very competitive team. We did better defensively. Offensively, this team are very organised and it's not easy to have a lot of chances. It's not good because we want to win but we are first, and this is our target."
