Yasiel Puig underwent an MRI on his right shoulder earlier this week before returning to the field with a limited throwing program.

The MRI revealed no serious injury and he was diagnosed with a return of inflammation that cropped up sporadically last year.

The Dodgers believe Puig tried to throw too much and too soon when position players began voluntary workouts earlier this week.

Whatever discomfort Puig feels in the right shoulder, however, hasn't hampered his swing, as he and Matt Kemp took turns launching bombs during batting practice in Friday's first full-squad workout.
