Arda Turan was sentenced to two years and eight months in jail for firing a gun to cause fear and panic, illegal possession of weapons and intentional injury.
However, the court deferred the verdict, which means the Barcelona midfielder will not go to prison unless he commits a crime in the next five years.
Barcelona midfielder Turan, currently on loan with Turkish club Basaksehir, was involved in a fight with Turkish singer Berkay Sahin in an Istanbul nightclub late last year, leaving the singer with a broken nose.
The footballer was alleged to have attacked the pop star in a fight over the singer's wife. Turan later arrived at the hospital with a gun which he fired at the ground, causing panic.
Turkish TV station published footage showing the aftermath of the incident outside a nightclub.
In the video, Turan is seen coming out of the club as the melee continues outside.
The footage also shows Turan entering the hospital and in discussions with someone, before throwing an object down on the table.
Turkish newspaper Haberturk reported that the the pair clashed after Turan made provocative remarks to the singer's wife, Ozlem Ada Sahin.
Basaksehir said they had fined the 31-year-old 2.5 million Turkish lira (£350,000) over the incident.
He joined Barcelona from Atletico Madrid for £30m in 2015, winning four trophies, making 55 appearances and scoring 15 goals for the Catalan club.
The midfielder has also represented Galatasaray, who he began his career with, before making his initial move to the Spanish capital in 2011.
Turan has played for Turkey 100 times and scored 17 goals for his country.
