Casey leaves with injured rib, back spasms
Casey was injured as he stretched to catch second baseman Jose Castillo's throw on John Mabry's infield single in the third inning. Mabry appeared to trip as he crossed the bag and, according to Pirates manager Jim Tracy, may have clipped Casey with his hip or elbow.
Casey took several strides toward the pitcher's mound before dropping to his knees in obvious pain. He was assisted off the field and needed help getting to the Pirates' clubhouse before being taken to a hospital for tests.
Casey, traded by the Reds to the Pirates during the offseason, returned to the lineup Friday after not starting three games because of a bruised left rib cage muscle.
The first baseman missed the final 16 games of last season with the third concussion of his career, also after being injured in Pittsburgh. He was accidentally struck in the head by Pirates catcher Humberto Cota's elbow as Cota was running out a ground ball during a Sept. 16 doubleheader.
