Manager Terry Francona said that Cameron is expected to play at least two more games in the Minors before being activated by Boston. The veteran, who has been sidelined with a lower abdominal strain, could return at some point this weekend, when the Red Sox play a three-game series at Philadelphia.
Though there was originally some hope Cameron could return for this two-game series in New York, Francona made it clear there were no setbacks.
"His body was sore," Francona said. "I think we wanted to make sure that it was his body being sore and not injured. We had him checked out pretty thoroughly. He worked out today like crazy. He went to Fenway, did all kinds of stuff. That's good news. We don't want him to come back and be 90 [percent], and then the next week be 85, then be 80. We want him to come back and have a chance to play and be good."
Meanwhile, left fielder Jacoby Ellsbury (left chest contusion) played the second game of his rehab assignment, going 0-for-3 at Portland. He will take Wednesday off from games and confer with the Red Sox before their game at Fenway. Ellsbury is expected to play some more Minor League games after that.
