Hedges was held out of Saturday's game after feeling some effects from taking a foul ball to the head Friday, AJ Cassavell of MLB.com reports.
It appears to be a precautionary move by the Padres, as they would rather not risk a head injury with their young catcher. Initial hopes are that a stint on the 7-day concussion DL won't be needed, though it will certainly be a situation worth monitoring over the coming days. Hector Sanchez will take Hedges' place as the starting backstop for Saturday's tilt.
