<![CDATA[Social media has transformed the relationship between athletes, sports organizations, fans, sponsors, and the public. Athletes increasingly use digital platforms to express opinions on sporting issues, institutional decisions, social matters, and personal experiences. However, sports organizations may impose disciplinary sanctions when athletes' online statements are considered damaging to institutional reputation or contrary to internal regulations. This article examines the legal limits of disciplinary sanctions imposed on athletes for social media expression in Indonesia. Using normative juridical research, the study analyzes freedom of expression, contractual obligations, sports disciplinary rules, and proportionality principles. The study argues that athletes do not lose their fundamental rights to expression merely because they participate in professional sport. Nevertheless, legitimate restrictions may apply where expression involves threats, discrimination, confidential information, or serious contractual violations. The central legal issue is therefore determining whether disciplinary restrictions are necessary, proportionate, and clearly established in advance. The article proposes a proportionality-based framework requiring clear rules, individualized assessment, procedural fairness, and meaningful appeal mechanisms. Such a framework would prevent disciplinary authority from becoming an instrument for suppressing legitimate criticism while preserving the legitimate governance interests of sports organizations. Balancing athlete expression and institutional integrity is essential for rights-based sports governance in Indonesia.]]>
