White (back) hasn't resumed any baseball activities yet, Martin Gallegos of MLB.com reports.
White has been dealing with lower-back tightness since Tuesday, and the team is expected to give him at least one more day to make recovery before making a decision on a potential stint on the injured list. The 23-year-old posted a .247 average with two home runs, three doubles, eight RBI and 10 runs scored in 26 games during August.
