The boss of Turkish football giant Fenerbahce faced a jail term over match-fixing on Thursday after a top court rejected his appeal, local media reported.
Aziz Yildirim, 61, was first sentenced to jail and fined 1.3 million lira ($580,000) in 2012 for match fixing during the 2010-2011 season.
In all, 93 people were originally convicted in the case and European football's governing body UEFA barred Fenerbahce from the Champions' League for two seasons as a result.
Yildirim served about a year of his original sentence before being freed pending an appeal against what he said was a "political" ruling.
On Thursday, the chief prosecutor's office within the Supreme Court of Appeals rejected his arguments and upheld his jail term of six years and three months, the private CNN-Turk television reported.
It marked the second time since January that the country's highest appeals court rejected his appeal.
It was unclear whether Yildirim would be able to appeal to the Constitutional Court.
His lawyer told AFP he had yet to receive official notification from the court on Thursday's ruling and would not issue any comments until he did.
Yildirim, a former professional footballer, became head of Fenerbahce in 1998 and was re-elected to the post in November despite the scandal.
The ruling comes with Fenerbahce on course for another Turkish league title, 12 and 13 points ahead of bitter rivals Besiktas and Galatasaray.
