Pederson said his neck was feeling better. He was diagnosed Tuesday night with a neck strain.
Just before crashing into Pederson, Puig sprinted from right field to right-center and caught Yadier Molina's long fly ball to end the 10th inning. Puig's left elbow appeared to knock Pederson on the side of his head, and Pederson's hat and glove went flying as the center fielder slammed face-first into the outfield wall.
Puig momentarily remained on his feet, raising his glove to show he had caught the ball, before grabbing his chest and dropping to the track.
Dodgers manager Dave Roberts said after the game that Pederson had taken a forearm to the jaw.
