Rollins said he "felt a little something" in the groin during the top of the fifth inning on Sunday, when he fielded three straight ground balls. But he played all nine innings.
"It wasn't anything that would take me out the game," Rollins said Monday. "I'm just taking a day off."
Sandberg said he was not worried about Rollins' health.
"Just felt a very little, small thing that he played through," Sandberg said. "He reported fine. It'd be smart to get him off his feet today. Also allows Freddy to get in there and play a game at short."
