Gage (elbow) will start his rehab assignment this weekend, Susan Slusser of the San Francisco Chronicle reports.
It's unclear which minor-league level Gage will start his rehab assignment at. Regardless, it's a positive step in his recovery from a left elbow strain that landed him on the injured list in early July. Given the nature of Gage's injury, the 33-year-old southpaw will likely need a few outings in the minors before being cleared to return to the Giants' bullpen.
