A case of ruptured rectus abdominis muscle in a professional volleyball player is presented and discussed. The injury was located near the deep fascia of the upper stomach muscle on the non-dominant side. This injury is rarely specifically mentioned in the literature and there are few reported cases. The injury mechanism is usually indirect at the time of the flexion/extension transition when serving or attacking in the case of volleyball. The player remains active despite the injury and for this reason the treatment had to be modified.
