Last I heard was that he's going to play catch sometime between Sunday and Wednesday and they'll re-evaluate then. It's not looking good from what I'm hearing though. At earliest he'd be 2 weeks from throwing off a mound (if he's progressing) and then a trip to Florida to work with Rick Langford and then rehab (again, if all is going well) and then back.
I'd say August 1st at the earliest, late August more likely and out for the season a possibility.
