Palacios was removed from Monday's contest against the Astros as a result of left hamstring discomfort.
Palacios pulled up lame on a ground out in top of the fourth inning, ultimately exiting the contest in the bottom of the fifth. He finished his day 0-for-2 with a strikeout and he can be considered day-to-day for the time being while more information on his status will likely come out in the near future.
