The AL East leaders made the announcement Monday.
Ellsbury has been on the 15-day disabled list since May 20 because of a sprained right knee.
Ellsbury was hitting .324 with 14 steals, and had scored 29 runs in 37 games when he was injured.
The 31-year-old Ellsbury has played four rehabilitation games for Class A Tampa and isn't scheduled to play again in the minors. He took part in simulated game activities Monday and is set to do that again Tuesday.
