After playing the last two games without Ryan Howard, the Phils took the field on Tuesday night without Chase Utley.
Howard returned after sitting out two games with a left knee injury, but Utley was a late scratch from the lineup after experiencing pain in his right side after pregame batting practice.
A Phillies spokesman said the injury was on Utley's upper right side. (Read: rib cage or oblique region).
Utley will be reevaluated on Wednesday.
Freddy Galvis started at second base in place of Utley against the Marlins.
