Troy (shoulder) is set to begin a rehab assignment with Triple-A Reno, Alex Weiner of ArizonaSports.com reports.
Troy has been sidelined since mid July after suffering a sprained right AC joint. He was initially expected to miss 3-to-4 weeks, though he's just now starting a rehab assignment, so it'll likely be at least a few days before he'll have a chance to be activated.
