This case study of an elite judo player recovering from injury provides an exemplification of a practitioner’s Professional Judgment and Decision Making (PJDM) using a ‘reflection-in-action research’ methodology. The process of “reflection-in-action” Schön (1991) and in particular the concept of ‘framing’ offer insight into how professionals think in action. These concepts assisted the practitioner in organizing, clarifying and conceptualizing the client’s issues and forming intentions for impact. This case study exemplifies the influence of practitioner PJDM on implementation at multiple levels of practice including planning the overall program of support, designing specific interventions to aid client recovery and moment-to-moment in-situ decision making session-by session. It is suggested that consideration of practitioner PJDM should be a strong feature of case study reporting and that this approach carries the potential to extend our use of case studies within applied sport psychology practice.
