The German playmaker was left out of Arsenal's matchday squad for the Premier League clash with West Ham United this afternoon, leading to reports that he had been involved in a training-ground dispute with Emery.
However, the official reason behind Ozil's absence was illness, and Emery insists that reports to the contrary have no truth to them whatsoever.
"Why is this information [out there]? It isn't true. I don't know who is telling you this information," he told reporters at his post-match press conference.
"He sat down with me and we decided that he would not play. He left training because he was going to his home because he is sick.
"Today he was here, I told him to come in if he feels better and he feels better today and before the match he was with the team. He is bad with sickness. There is no problem with the player, speak with the doctor he can explain better."
Arsenal won their first game of the season in Ozil's absence, coming from behind to beat West Ham 3-1 at the Emirates Stadium.
