Mesoraco exited Tuesday's game against the Brewers with a bruised right wrist.
Mesoraco was hit by a pitch in the second inning Wednesday, but remained in the game until the sixth inning. Fortunately, X-rays came back negative so it looks to be a day-to-day injury for the 29-year-old, although he could be held out Wednesday with the Reds' off day Thursday providing potential for an additional day of rest.
