Ozil has been excluded from Fenerbahce's squad indefinitely after reports of a verbal altercation with the club's interim manager and a lack of fitness in their last game.
The 33-year-old former Germany international has made 37 appearances for the Turkish giants since joining from Arsenal in January last year.
"Our Football A Team players Mesut Özil and Ozan Tufan were excluded from the squad as per the decision taken. It is announced to the public," a statement read.
Football.London reports Ozil was involved in a verbal altercation with interim manager Ismail Kartal in their victory against the second-placed side.
Ozil's public exclusion from the squad prevents him from training with the first team ahead of their away fixture this weekend against 14th-place Kayserispor, the report adds.
