An employee reported having gotten their fingers caught in a set of pinch rolls. The fingers are badly bruised with several lacerations. The supervisor is unsure if any of the bones are broken or if sutures need to be applied, so the employee was taken to the local hospital. As part of the examination in the ER, the doctor ordered X-rays which were negative for fracture. A nurse then cleaned and bandaged the wounds. The employee was released to return to work tomorrow and told to take an aspirin if they experienced pain or throbbing. Using CFR 1904, decide the classification of this case
