PITTSBURGH (AP) Chicago Cubs centerfielder Emilio Bonifacio has left Thursday night's game against the Pittsburgh Pirates due to a rib injury.

Bonifacio stumbled out of the batter's box and fell to the ground after hitting a routine grounder to first to start the game. Bonifacio lay still for several minutes before being helped to the dugout by team personnel.

Chris Coghlan replaced Bonifacio's spot in the batting order and Junior Lake moved from left field to center.

Bonifacio began the day hitting .425 (17 of 40) against the Pirates this season.
