Stewart left Saturday's game against the Cardinals in the seventh inning with a left foot injury following a collision at the plate, Bill Brink of the Pittsburgh Post-Gazette reports.

EDGE Analysis

Making his first start in place of Francisco Cervelli, who was placed on the DL earlier Saturday and ruled out for four-to-six weeks with a broken bone in his left hand, Stewart couldn't get out of the game with his health in tact. He had already been limping around prior to the game after fouling off two pitches on the foot earlier this week, and aggravated the injury after the collision. Stewart's departure forced the Pirates to throw Erik Kratz into the fire right away behind the plate, after the veteran catcher was acquired Saturday from the Angels. It's likely that Stewart will garner the majority of the starts while Cervelli is out, but if Stewart's foot injury ends up sidelining him, Kratz would be next in line for increased opportunities in the lineup.
