The Red Sox announced that Contreras was removed from Sunday's game against the Rays due to a bruised right hand, Tim Healey of The Boston Globe reports.
Andruw Monasterio covered first base to begin the second inning after Contreras was hit by a pitch in the bottom of the first. While preliminary X-rays have ruled out any sort of fracture, he could be subject to further tests. Contreras will benefit from a team off day Monday before the Red Sox begin a three-game series with the Phillies on Tuesday.
