Pollock ran the bases before Friday's game against the Padres, but sustained another setback. The D-backs then decided he won't play in this final series of the season.
"He ran fine on the grass and then when he ran on the bases, he felt it again, so we shut him down," manager Chip Hale said. "He will not be getting in any of the games this weekend, unfortunately. It was disappointing for him. He felt really good the last three or four times he ran, felt like he was giving it all, just on the dirt he could feel it.
