Ramirez has suffered through a litany of minor injuries this season but only once has landed on the disabled list, missing 14 games in August with an oblique strain.
The shortstop has a five-game hitting streak and is hitting .444/.500/.556 (16-for-36) with nine RBI in his last 10 games, but has apparently been icing the elbow since the weekend series against the Giants in San Francisco, per Ken Gurnick of MLB.com.
Ramirez was 2-for-4 with a double in Monday's series opener.
Ramirez was originally slated to bat fifth, but now Justin Turner will start at shortstop and bat sixth. It is the seventh start of the season at shortstop for Turner, who has also started 43 games at third base, 11 at second base and two games at first base this season.
Scott Van Slyke, starting against the left-handed Tyler Matzek for Colorado, was originally sixth but will now bat fifth and play left field.
