Emilio Bonifacio injures rib cage
After making contact, Bonifacio fell to the dirt with what the team described as an injury to his right rib cage.
The Cubs were shut out, losing to the Pirates 4-0.
Bonifacio will receive additional evaluation, according to the team.
"He'll get checked out in the morning in Chicago, and we'll see where he's at and make a determination after [that]," manager Rick Renteria said.
