Puig said he felt his back begin to stiffen during batting practice. He grounded out sharply in the first inning and his back locked up while taking a big swing during a fourth-inning walk. He then scored on Brett Eibner's two-run homer.
"I feel better with the treatment and the stuff they do to me, I feel better," he said. "I might play tomorrow or the next day, Sunday."
Puig was replaced before the top of the fifth inning in the outfield, with Eibner moving from center field to right field and Joc Pederson taking over in center.
