Ellsbury was removed early from Wednesday's game against the Royals with a neck sprain and a concussion, Bryan Hoch of MLB.com reports.
EDGE Analysis
Ellsbury was forced out of the contest after just one inning following his collision with the outfield wall. Although nothing is confirmed, this will likely send him to the 7-day disabled list. He'll be re-evaluated Thursday, and if he is forced to go on the DL, expect Aaron Hicks to take over the bulk of center field duties in his absence.
