Mert Hakan Yandaş and Metehan Baltacı #

Introduction #

Mert Hakan Yandaş and Metehan Baltacı are Turkish professional footballers who became two of the most prominent names caught up in the betting scandal that swept Turkish football in late 2025. Yandaş, then 31, was the captain of Fenerbahçe, one of the country’s biggest clubs, while Baltacı, 23, was a young centre-back at arch-rival Galatasaray. On December 5, 2025, prosecutors in Istanbul ordered the arrest of 46 people — 29 of them players — as part of an investigation into illegal betting and match-fixing, and both men were among those detained. Yandaş stood accused by prosecutors of placing illegal bets on matches through a third party, and Baltacı of betting on matches involving his own team — allegations, not established findings, in proceedings that were still unfolding into 2026.

Background Information #

Yandaş was born on August 19, 1994, in Bursa, Turkey, and came up through the youth ranks at Bursa Güven and Yeşil Bursa before senior spells at Altınordu, Tirespor 1922, and Menemen Belediyespor. He joined Süper Lig side Sivasspor in July 2017 and moved to Fenerbahçe on a free transfer in August 2020, becoming a mainstay who passed 100 appearances in all competitions for the club in August 2023. He was capped once by Turkey, in a September 2020 UEFA Nations League match against Hungary, and on August 5, 2025, he was named captain of Fenerbahçe.

Baltacı was born on November 3, 2002, and joined Galatasaray’s youth academy in 2012. He began his senior career on a season-long loan at İskenderunspor in 2021, made his senior Galatasaray debut in a 7–0 Turkish Cup win over Kastamonuspor in October 2022, and later spent loans at Manisa and Eyüpspor, winning the TFF 1. Lig title with the latter in 2023–24. Back at Galatasaray, he was part of title-winning squads and made 12 appearances for Turkey’s under-21 side.

The Controversy or Incident That Led to Their Cancellation #

On the morning of Friday, December 5, 2025, Istanbul prosecutors ordered the arrest of 46 people, 29 of them players, in the investigation into illegal betting and match-fixing that had come to dominate Turkish football. The prosecutor’s office said 35 of the 46 had already been detained, with five of the remaining eleven believed to be abroad. “Efforts to apprehend the other suspects are ongoing,” the office said in a statement naming all 46 of the accused. “Investigations will continue with meticulousness and determination.”

Per the BBC, Yandaş was accused by prosecutors of making illegal bets on matches through a third party, and reports in Turkey said he had been detained by police; the Fenerbahçe captain’s home was raided in the operation. Per Wikipedia, citing Turkish outlet Medyascope, he was detained that day after it was determined he had placed bets on legal betting sites through another person.

Baltacı was also among those arrested, accused of betting on matches involving his own team — an offence under football’s rules, which ban players from betting on any matches, involving their own team or not, over match-fixing and sporting-integrity concerns. Wikipedia, likewise citing Medyascope, records that he was detained on December 5, 2025, after it was determined he had placed bets on legal betting sites. Twenty-seven of the 29 arrested players were alleged to have bet on matches their own teams played in. The wider sweep went beyond players: the list also included club officials and coaches over an allegedly fixed April 2024 match, a former club president, commentator and former referee Ahmet Çakar, and top-flight referee Zorbay Küçük.

Public Reaction and Consequences #

The scandal had already convulsed Turkish football before the December arrests. In October 2025, the Turkish FA’s president, İbrahim Haciosmanoglu, accused hundreds of referees of being linked to betting accounts, and the following month the federation suspended more than 1,000 players over alleged betting infractions. Baltacı had been among those punished: on November 13, 2025, per Wikipedia, he was banned for nine months for his alleged involvement in the scandal — a suspension the BBC referenced as recently handed down when he was arrested weeks later.

For Yandaş, the consequences struck at the peak of his club career. He had been made Fenerbahçe captain only in August 2025, but per Wikipedia he lost the captaincy to Milan Škriniar as a result of the betting allegations. The arrests landed in a season in which Galatasaray sat top of the Süper Lig, one point ahead of Fenerbahçe, after 14 matches. Both men remained under formal criminal accusation, with the allegations untested in court and neither treated by the authorities’ own process as convicted of anything.

Current Status #

The two cases moved at different speeds through 2026, but both remained legally unresolved. Per Wikipedia, on February 27, 2026, an indictment was prepared against Yandaş seeking a prison sentence of 4 to 13 years; an indictment seeking a sentence is a prosecutorial request, not a conviction, and on April 3, 2026, the court issued a release order for him. The same indictment date and sought sentence are recorded for Baltacı, who per Wikipedia was released on March 25, 2026, after a period remanded in custody. Baltacı’s club career resumed on August 22, 2026, when, per Wikipedia, he signed a loan agreement with Gençlerbirliği running to the end of the 2026–27 season, remaining a Galatasaray player. As of the latest available information, proceedings stemming from the investigation remained pending, and both men are presumed innocent unless and until proven guilty in court.

Impact on Their Career/Life #

For Yandaş, the scandal transformed his standing at Fenerbahçe within months: from club captain to a detained suspect whose home was raided and whose armband went to Škriniar, with a 4-to-13-year sentence sought in the indictment prepared against him before his release in April. For Baltacı, a 23-year-old academy product once viewed as a development success story, the episode meant a nine-month ban from the Turkish FA, arrest and pre-trial custody, and release only in March 2026 — before a loan to Gençlerbirliği gave him a route back onto a pitch in August 2026. Their cases sit within the largest integrity crisis in Turkish football history, one in which more than 1,000 players were suspended in a single month and dozens of figures across clubs, refereeing, and broadcasting faced arrest — a reckoning whose final legal outcomes had yet to be determined.
