Bradley, the Cubs' main offseason acquisition, didn't play in Monday's 4-0 victory over Colorado in Chicago's home opener. He had to leave Sunday's game in Milwaukee in the fourth inning after pulling up as he ran the bases.
"I talked to our team doctor and he told me three to five days. That's what he mentioned to me," Cubs manager Lou Piniella said Monday.
Bradley has gotten off to a slow start, going 1-for-17.
