Puig had an MRI exam on Wednesday morning that showed a very mild hamstring strain, one that won't require a stint on the disabled list.
"[The news] was really positive," manager Don Mattingly said. "Stan [Conte, team trainer] categorized it as really mild. [Puig]'s day-to-day. Friday we'll test in in Houston."
Puig left Tuesday night's game in the eighth inning after beating out an infield single, extending his hitting streak to five games. Mattingly said Puig likely won't be available to pinch hit on Wednesday, trying to use Thursday's off day to give Puig two days of rest before the weekend series against the Astros.
The Dodgers will have three more games with the designated hitter, so Puig could hit if he's ready and not have to play the field.
"We can be a little more cautious, too, with the DH in Houston," Mattingly said. "We'll go with whatever medical says."
With Puig out on Wednesday, Andre Ethier starts in right field for the Dodgers against right-hander Jesse Chavez for the A's, with Carl Crawford in left field.
Scott Van Slyke serves as the designated hitter for the series finale.
The A's placed first baseman Ike Davis on the disabled list with a left hip strain, and recalled Jake Smolisnki from Triple-A Nashville. Smolinski starts in left field, batting fifth on Wednesday.
