Journalist Murat Aksoy will be sent back to prison after a regional appeals court upheld a two year, one month sentence handed down by a local court on conviction of supporting a terrorist organization.
Aksoy was not convicted of membership in the organization.
Aksoy was first arrested in September 2016 along with 28 other journalists as part of a crackdown targeting alleged followers and sympathizers of the Gülen movement.
He was released pending appeal in October 2017.
The movement is accused by the Turkish government of orchestrating a failed coup in 2016 although it strongly denies any involvement.
Since then, over 200 journalists have been put behind bars primarily on coup-related charges.
In a tweet posted on Tuesday, Aksoy said he would surrender himself in two days.
In a similar case, columnist and former pop singer Atilla Taş was sent to prison after a regional court upheld his conviction on Nov. 9.
