Murcer To Face New Brain Cancer Trial. According to an e-mail sent out by his wife, Bobby Murcer may have to defeat brain cancer for a second time. Murcer must undergo a brain biopsy on Monday to determine if an area of concern for doctors - which appeared during a recent MRI - is another tumor or simply scar tissue. Speaking for myself, every true Yankees fan and all of Major League Baseball, let's hope it's the latter. Our thoughts and prayers go out to the Murcer family.
