D'Arnaud (back) is not in the lineup for Sunday's game against the Nationals.
With Noah Syndergaard on the bump, Rene Riverahis usual battery mate, will draw the start behind the plate. D'Arnaud, who has seven RBI in his past three games, is dealing with back tightness and is being considered day-to-day. With Sunday's day of rest, he'll hopefully be ready to go for Monday's contest against the Braves.
