Industry sources, both with direct knowledge of Manny Ram?rez's condition, had conflicting reactions to a report by Will Carroll posted on the Baseball Prospectus website, in which Carroll wrote that Ram?rez has a small tear in the medial meniscus of his right knee. ``It's an injury he can play with," Carroll wrote, ``but one that can `grind' a bone-on-bone situation that is unpredictable and painful." One source, although not offering direct confirmation of Carroll's report, acknowledged some degree of accuracy. Another source, however, said neither the Red Sox medical staff nor an outside entity have administered an MRI to Ram?rez and have not indicated they intend to do so. Without an MRI, the source said, the Sox would only be guessing there is a tear.
