Athletics manager Mark Kotsay said Wednesday that Kurtz will undergo an MRI on Thursday after X-rays on his left forearm were "kind of unclear," Martin Gallegos of MLB.com reports.
Kurtz was forced to depart Wednesday's contest versus the Red Sox after being struck on the forearm by a Patrick Sandoval pitch. The Athletics should offer an update on the star first baseman's status later Thursday. Kurtz just returned from the injured list less than a week ago after missing time with a thumb injury.
