The Turkish Football Federation (TFF) on Friday suspended 149 referees for alleged involvement in match betting.

In a statement, the TFF announced that its disciplinary committee had imposed bans ranging from eight to twelve months, adding that investigations were still ongoing into three additional referees.

The probe, which reviewed 571 referees across Turkey’s professional leagues, revealed that 371 had sports betting accounts, while 152 were actively placing bets.

“Refereeing is a profession of honour,” TFF President Ibrahim Haciosmanoglu said on Thursday. “Anyone who tarnishes that honour will never again take part in Turkish football.”

According to the federation, 22 of the officials under scrutiny — including seven match referees and 15 assistants — officiated in the top division.

The investigation also found that 10 referees placed more than 10,000 bets each, with one individual logging 18,227 wagers. Additionally, 42 referees were found to have bet on over 1,000 football matches.

While the TFF did not confirm whether any of the referees had bet on games they officiated, the Istanbul public prosecutor’s office has opened a separate criminal investigation into the matter.
