Why Abdoullah Ba’s Sivasspor Move Collapsed: Medical Report

Sivasspor’s last piece of summer transfer business was supposed to be a low-cost, high-experience midfield reinforcement. Instead, it fell apart on the examination table. Abdoullah Ba, a fringe Sunderland midfielder, failed his medical in Turkey after scans in Sivas and a follow-up in Ankara revealed chronic knee damage — and the move was scrapped before he ever put pen to paper. Here is the full story, his scouting profile, and where Sivasspor go from here.

The Story So Far

Turkey’s summer transfer and registration window officially closed at midnight on Friday, 4 September 2026, and Sivasspor spent the final days chasing a proven, experienced body for central midfield. That search led them to 23-year-old Abdoullah Ba, a player who had drifted to the fringes of Régis Le Bris’s plans at Sunderland.

According to Turkish and English reporting, talks nearly collapsed on the Thursday before deadline day, then were revived within hours, with the two clubs reaching a working agreement (status: advanced negotiation, reported by multiple outlets). As is standard procedure, Ba then travelled for a medical — first in Sivas, and when the initial results weren’t conclusive, at a private hospital in Ankara for more detailed imaging.

That is where the deal died. The scans showed chronic meniscus and cartilage damage from an old knee injury, and Sivasspor’s medical staff concluded the knee would not hold up to a full season of high-intensity Süper Lig fixtures. Club management chose not to take on the risk, and Ba flew back to France without signing (status: transfer called off, confirmed across multiple sources). As of writing, Sivasspor have issued no formal written statement on the collapse; the account here is built from cross-referenced Turkish outlets (HaberGo, Sivas İrade, Spor Depor) alongside UK reporting from Sunderland Echo and Sport Witness. Ba’s camp is reportedly seeking a second medical opinion to determine whether surgery is required.

Scouting Profile: Who Is Abdoullah Ba?

Abdoullah Mustapha Ba was born on 31 July 2003 in Saint-Aubin-lès-Elbeuf, France, and is of Mauritanian descent. Some Turkish outlets have described him as Senegalese, but both Sunderland’s official player page and his career records list his nationality as French — worth clarifying for accuracy.

Standing 1.80m, Ba came through Le Havre’s academy and made 26 league appearances for the club’s first team between 2020 and 2023. He joined Sunderland on a five-year deal in August 2022 and racked up 66 league appearances and 4 goals through the end of 2024-25. But with playing time drying up under Le Bris, he spent 2025 on loan at Ligue 2 side USL Dunkerque (7 appearances, 1 goal) before returning to Wearside to find himself almost entirely frozen out this season.

Positionally he is a central midfielder who has also been used further forward in a wide-midfield role. His game is built around ball-carrying after winning it back and driving into advanced areas — a profile suited to transition football. With just under a year left on his Sunderland contract when talks began, he represented exactly the kind of low-risk, Premier-League-tested value signing an Anadolu club looks for late in a window.

Fit With Sivasspor’s Needs

Sivasspor rebuilt their midfield this summer around Ghanaian holding midfielder Musah Mohammed, plus Salih Kavrazlı from Bursaspor and loanee Clinton Duodu from Apollon Limassol. Ba was meant to be the fourth piece — a top-flight-tested option who could arrive cheaply given his diminished role at Sunderland.

With the move dead, priorities shifted fast. Local reports indicate the technical staff are now weighing two alternative profiles: an experienced Süper Lig midfielder on loan, or a short-term deal with a free agent. The club’s technical committee reportedly met to decide on next steps at the end of the week the medical results came in.

What Tactical Impact Would He Have Had?

Had the move gone through, Ba’s likely value to Sivasspor was as a midfielder who could both screen the back four and carry the ball into the final third — a profile that would slot into the advanced pivot role in whichever of Sivasspor’s usual 4-2-3-1/4-3-3 shapes the coaching staff selects. Given the side’s stated aim of moving the ball forward more quickly in transition, his vertical carrying and space-creation would have offered a genuine alternative out of midfield. This remains, by necessity, a hypothetical: since he never played a minute for the club, the assessment rests entirely on his career data rather than any on-pitch evidence in a Sivasspor shirt.

The Financial Picture

No transfer fee was reported publicly. Given how little of his Sunderland contract remained, reporting suggests the move was being negotiated on cut-price or nominal terms, with Sunderland reportedly open to either a sale or a contract termination (tag: reported, unconfirmed figure). With the deal collapsing, Sivasspor avoid both the transfer outlay and any related fees, and are expected to redirect that midfield budget toward an alternative target.

A Pattern, Not an Isolated Case

Ba isn’t the only medical-related casualty of this transfer window. Fenerbahçe’s planned move of Jayden Oosterwolde to AS Roma unravelled in a similar way: after an initial medical, the Italian club requested further tests, judged his recovery timeline too long, and then asked for a discount that ended the negotiation. Both cases point to the same trend — as deadline-day deals get compressed into ever-shorter windows, the medical has stopped being a formality and become a genuine deal-breaker. Compared with Sivasspor’s other completed loan business this window, such as forward Ebrima Ceesay, the Ba file stands out as the club’s riskiest, highest-profile attempted signing of the summer.
