Pedroia plans to return to Boston today to have an examination, and if he does elect to go through with the surgery it could sideline him for a month. But as with any surgical procedure, that timetable is only a best estimate.
It seems clear that the injury is affecting Pedroia's performance. Limping through a virtual season-long slump, the former MVP is in the process of putting up his worst numbers since making a brief 31-game debut in 2006. Neither Pedroia nor the can team carry on this way.
After posting impressively consistent OPS totals of .869, .823, .819 and .860 over the past four years, Pedroia's current total stands at a paltry .695. He's batting only .246 and his production has tanked. Pedroia has already struck out more this season (39 times) than he did in 75 games last year.
The hope is that surgery will eliminate the pain, which will get his mechanics back on track. As Pedroia himself put it, "It's hard to hit with something wrong with your legs."
The question is how should Boston proceed in his absence? Let's run through the potential changes, beginning with the most obvious and most likely solution.
6pm eastern: Sean McAdam has reported via Twitter that Pedroia's knee exam led to the diagnosis of a bruised kneecap. Any arthroscopic surgery or cartilage issues as discussed by the Boston Globe and other sources will apparently be put on hold for time being. Great news for the Sox.
