Manager Walt Weis said Tuesday that Acuna (hamstring) could begin a rehab assignment next week, Mark Bowman of MLB.com reports.
The 28-year-old has been on the injured list due to a hamstring strain for about a month, but he's nearing the final stage of his rehab program. Acuna won't be rejoining Atlanta before the start of the All-Star break, though he may not miss much time, if any, to begin the second half of the season.
