Ozil had been on the training ground on Thursday "running and touching the ball", Emery told a press conference.
Mesut Ozil has missed Arsenal's last four matches and it is expected that he might be absent when the Gunners host Huddersfield Town on Saturday.
Arsenal coach Unai Emery gave an update on the fitness of attacking midfielders Mesut Ozil and Aaron Ramsey.
While speaking to media, Emery said, "He had backache and now he is working with one physio. We are going to look when he can come with us."
Ozil is being treated for a back problem and manager Unai Emery has hinted that he could be passed fit on Friday if he comes through sessions with the club's physiotherapist unscathed.
He said, "Tomorrow is the training, the last training before (Saturday's match), today, this morning, he was working with a physio, but on the pitch, running and touching the ball. And tomorrow is the decision."
Ozil's absence mattered little as the Gunners' unbeaten run simply carried on without him.
Emery called on the club's supporters to get behind the team, to help finish off a series of three games in seven days with seven points following the 4-2 victory in the North London derby last Sunday and the 2-2 draw at Manchester United on Wednesday.
