"He's fine," D-backs manager Kirk Gibson said, before saying that he just decided to go with Xavier Nady on Friday night.
Miranda was a late scratch from Thursday's lineup because he wasn't feeling well, but he did make a pinch-hit performance in the seventh inning, grounding out to first base.
Gibson said following the loss that Miranda's scratch was related to a collision with pitcher Daniel Hudson the night before.
"He didn't feel tip top so we made a change," Gibson said. "It was something with his neck."
Miranda said on Friday that he hit his neck on the field during the collision, but that he's feeling better.
"I'm ready," he said, adding that he expected to be back in the lineup on Saturday.
