Ramirez also received some long-term good news. A doctor who examined Ramirez's shoulder told him he probably won't need surgery to tighten the shoulder capsule.
Ramirez dislocated the shoulder May 8 and was on the disabled list until July 6. He hasn't played since leaving a game in Colorado on Saturday.
"I have a pretty good idea of what I can tolerate," Ramirez said. "In Colorado I tried, but I couldn't do it. It was too painful. But I don't want to miss any more games. I've already been out of the lineup enough."
The Cubs open a series against the Pittsburgh Pirates on Friday.
