Ellsbury (knee) will go on the 15-day DL, YES Network's Jack Curry reports. Ellsbury suffered the knee injury in Tuesday's game and was slated for an MRI following the game, which apparently revealed something that would take at least a couple weeks to heal. It is still not clear how serious the injury is, but we at least know Ellsbury will be out until early-June. Slade Heathcott was recalled from Triple-A to offer depth in center field, but look for Chris Young to see the majority of the starts while Ellsbury is out.
