IE and 2 other co-workers were placing a hog panel against the rib. A sharp edge of the hog panel stuck into the IE finger. On 12/9/18 the IE went to the Dr. to see if there was any metal in finger. Upon examination the x-ray showed a sliver of metal in left pinky finger. IE continued to work, referred to a specialist on 12/14/18 to have the sliver of metal removed.
