Acuna (hamstring) isn't expected to be activated from the 10-day injured list until at least Sunday, Ian Quillen of MLB.com reports.
Acuna had been scheduled to play a rehab game at Triple-A Gwinnett on Friday, but a rainout muddles Atlanta's plans for activating the star right fielder. Gwinnett has a doubleheader scheduled for Saturday, and MLB manager Walt Weiss didn't rule out Acuna playing both ends of it before rejoining the big club. Atlanta planned to have the 28-year-old back in its lineup this weekend, so a Sunday activation remains possible. Acuna has been sidelined since June 9, and over 53 games for Atlanta this season he's managed a .794 OPS with seven home runs and 15 steals.
