Lee day-to-day after exiting opener
X-rays on first baseman's right thumb negative

Lee was taken out of Monday's game after the fourth inning because of pain and inflammation in his thumb. He grimaced after he singled in the third inning of the Cubs' 9-5 win over the Milwaukee Brewers, and again after he singled in the fourth. He was replaced at first by Xavier Nady, who started the game in right field.
"[Lee] hit a ball that jarred his finger a little bit so we got him out of the ballgame," Cubs manager Lou Piniella said. "He had some swelling in it."
Lee has been bothered by the thumb since Wednesday, when he jammed it sliding into second base in the eighth inning in Atlanta.
