Miles was hit by a pitch from right-hander Mike Pelfrey in the fifth inning of Tuesday night's 6-0 loss to the Mets. He took the field in the sixth but left after experiencing discomfort.
"I tried to stay in but throwing didn't feel so good," Miles said Wednesday.
Dodgers manager Don Mattingly said Miles is available to pinch hit if needed. Infielder Jamey Carroll was listed as the starting second baseman Wednesday.
Miles, 34, is batting .320 this season and has raised his average 15 points in his past 10 games. He is fifth on the team in hits (73), trailing only center fielder Matt Kemp (101), right fielder Andre Ethier (99), first baseman James Loney (86) and Carroll (79).
