The team has been waiting for the swelling in his shoulder to go down since tests are difficult to conduct under those circumstances. It's been nearly two full days since Ellsbury was hurt in the fourth inning Friday afternoon against the Rays, on a takeout slide he made at second base.
"The 48-hour period is almost done where the ice will no longer have any effect, I guess, or have any benefit," manager Bobby Valentine said Sunday morning. "That's the period we're waiting to get over, where the swelling is controlled as much as possible. Then I believe there'll be another evaluation."
Ellsbury is likely out for at least a month and a half, and Valentine said Saturday that surgery was not a word he had heard. The matter will become clearer once doctors are able to conduct further examinations.
Jason Repko was called up from Triple-A Pawtucket on Sunday and started in center field against the Rays, while shortstop Mike Aviles again filled in as the leadoff hitter after going 3-for-5 in that role on Saturday.
