Josh Thole (concussion) was pulled from a rehab start with Triple-A Buffalo Wednesday because MLB's Players' Association did'nt approve Thole's rehab assignment in time for him to play. It's the first we've ever heard of such an incident, but ultimately it's not a big deal. He ended up entering the game in the eighth inning after receiving clearance, so the Mets should be able to stick to their plan of catching Thole Thursday and activating him Friday.
