Bradley singled in his first at-bat, one of a Major League record-tying eight straight hits by the Cubs in the first against Pirates starter Zach Duke, and flew out to end the inning.
Cubs manager Lou Piniella had planned on giving Bradley Wednesday off, and decided to do so early after the team opened a 7-0 lead in the first. The leg problems are not serious, and Bradley was expected back on Friday when the Cubs open a seven-game homestand against Cincinnati.
Bradley was 5-for-18 on the Cubs' road trip with a double and two RBIs. Micah Hoffpauir took over in right field for Bradley in the second inning Tuesday.
