Turan has been banned for 16 matches after the Turkey international pushed a match official.
The midfielder, on loan from Barcelona at Turkish Super Lig side Istanbul Basaksehir until 2020, was furious at a decision made by the assistant during Friday's 1-1 draw with Sivasspor. An irate Arda shoved the official in the chest and was quickly dismissed by the referee.
The suspension means Arda will miss a large chunk of the 2018-19 season as well as the conclusion of this term.
Basaksehir, three points behind leaders Galatasaray in third with two games remaining, are aiming to win the Turkish title for the first time.
