Arcia (hamstring) will begin a rehab assignment at Triple-A Gwinnett on Saturday.
Arcia has been on the injured list since Aug. 10, and the club has been targeting a September return. The 28-year-old's rehab assignment should be the final step in his recovery process, but he'll likely need to appear in several minor-league games prior to rejoining the big-league club. If he feels good following his rehab games, he'll likely be in the mix to return from the injured list sometime next week.
