Peter Abraham of the Boston Globe writes that Andrew Bailey (thumb) "may not be back until late August or September." Bailey has yet to resume throwing from a mound since having a setback a couple weeks ago. He'll need a few bullpen sessions before going out on a rehab assignment, an assignment that's expected to last 15-20 days. It also appears as though he'll return as a setup man, so mixed leaguers can probably cut Bailey loose at this point.
