Williams underwent tests on his right elbow Wednesday after experiencing some pain, Adam McCalvy of MLB.com reports.
General manager David Stearns said he "has no idea whether this is nothing at all, or something more than that," which certainly doesn't instill much confidence in any of Williams' dynasty league owners. The pitching prospect was examined by Brewers head physician William Raasch and could head in for an MRI if Raasch recommends it. For now, consider the right-hander day-to-day until a more firm diagnosis comes forth.
