Whether a treating physician can testify as a fact witness absent an expert designation

QUESTIONS PRESENTED FOR REVIEW 1. In the case at bar, Petitioner’s Treating Physician was precluded from testifying as a Fact Witness and as an Expert Witness because the Treating Physician was not designated as an Expert Witness. Where a Treating Physician is situated to testify as both a Fact Witness and an Expert Witness, can the Treating Physician be barred from testifying as a Fact Witness simply because the Treating Physician was not designated as an Expert Witness? 2. If allowed to testify as a Fact Witness absent an Expert Designation, can a Treating Physician also provide Expert Testimony?
