Johnson (hand) is on track to be activated in advance of next Thursday's game according to manager Fredi Gonzalez, Mark Bowman of MLB.com reports. Johnson was initially expected to miss 3-to-6 weeks after suffering a left hand fracture in the end of April, so a May 28 return would put him in the earlier portion of that timetable. Alberto Callaspo has seen most of the work at third base in his absence, but Johnson figures to slot back into an everyday role once he's healthy.
