Beckett apparently pulled his oblique in a bullpen session this past Friday. Manager Terry Francona revealed that he won't pitch until the third game of the Divisional Series against the Angels. The coaching staff considered using him in Game 2 and said they were confident he'd be able to go in Sunday's Game 3.

In Francona's own words:
I don’t think we would slot him in. Now certainly, if it goes the wrong way, we’re going to use pretty good, hopefully very good, judgment. But I think that we’re slotting him in there because we think he can pitch there. I don’t think – Friday was actually discussed. I think after Theo [Epstein] and I and John Farrell talked about it more and more and more, we thought that was pushing it. Because then you’re messing around with maybe cutting short a side session. It’s not just health, but it’s competing also. He has to be able to go out there and execute his pitches. I think he’s going to be OK.
