The physician opined that, based on his examination of the claimant and his medical records, "since there was no evidence of medical impairment, Claimant had made a full and complete recovery." Id. The Court accepted the physician's testimony as competent. Id. The Court rejected the argument that an employer's doctor's testimony was incompetent to support a termination of benefits where the doctor opined "he was unable to see how the work injury could possibly happen."
