Ellsbury (knee) will undergo an MRI and will miss some time, although it is still unclear how serious the injury is, Newsday's Erik Boland reports. The Yankees will await results of the MRI before setting a timetable for his return, but it sounds like a DL stint could be a possibility. Chris Young is now worth an add in deeper leagues as he figures to see the bulk of the playing time in center field while Ellsbury is out.
