The Pirates announced Tuesday outfielder Andrew McCutchen suffered an avulsion fracture of cartilage near his left rib, but are not yet planning to place him on the disabled list.
"We continue to evaluate Andrew’s progress and he will remain on the active roster," general manager Neal Huntington said. " We want to take the appropriate time to make the best possible decision for Andrew and for the Pirates."
McCutchen suffered the injury while swinging Sunday, one day after he was hit in the back by a pitch against the Diamondbacks.
