FC Barcelona has opened disciplinary proceedings against goalkeeper Marc-André ter Stegen after he refused to sign his medical report, which would have allowed the club to share details of his back injury with LaLiga's Medical Commission. Ter Stegen's refusal has complicated the club's efforts to comply with financial fair play regulations, as the medical evaluation was intended to justify a portion of his salary being freed up to register new signings. The club initially sought a resolution through meetings and hoped Ter Stegen would reconsider, but relations deteriorated, leading Barcelona to temporarily strip him of the captaincy. Ronald Araujo, the team's vice-captain and center-back, has assumed the role of first captain. The German Football Federation has applied pressure on Barcelona regarding the situation, while LaLiga and the Spanish players' union (AFE) support Ter Stegen's legal right to keep his medical information private. Barcelona is exploring legal options to resolve the impasse, asserting confidence in their position under the LaLiga-AFE agreement. The dispute reflects a broader tension between the player and the club, with the captaincy issue set to be addressed during the team's return to training. Ter Stegen remains with the club and is firm in his decision not to sign the medical report.
