Schafer was on the disabled list from Aug. 7 to Sept. 1 with a separated left shoulder.
"It's slowly gotten better, but it's not to the point to where I can really do anything yet," Schafer said. "I've tried the last couple of days, but it still bothers me and I haven't even tried to swing yet. It was getting better until I dove in Cincinnati and I landed awkward again, and it hasn't gotten [completely] better."
Schafer, who's hitting .211 this season, is hoping to get back in the batter's box by the end of the season, which is less than two weeks away.
"We don't have too much time for it to get better," Schafer said.
