Manager Bob Melvin revealed Friday that Crisp (neck) is dealing with kidney stones and is resting at home, Susan Slusser of the San Francisco Chronicle reports. Crisp's status for the remainder of the season was already in peril due to a neck injury that may end up requiring surgery, and the kidney stones add only another complication to the outfielder's recovery process. At this point, the Athletics are likely not even thinking about when Crisp will resume baseball activities; his long-term health remains the greater priority.
