Ellsbury's injury is being labelled a right patella injury, and he was sent back to New York for an MRI, the New York Post reports.

EDGE Analysis

Both Ellsbury and Starlin Castro were forced out of Saturday's loss with injuries, but manager Joe Girardi sounded more optimistic about his center fielder, saying that his hope was that it was "just a bruise and couple days off." The results of the MRI should clear up a timetable, but it would appear that the best case scenario would still sideline Ellsbury for a couple of days. Brett Gardner slid from left to center in his absence Saturday, while Tyler Austin entered the game in left field, which is an alignment they may continue to deploy for any games the 33-year-old is forced to miss.
