Garver was diagnosed with a bruised right hand after undergoing X-rays on Tuesday, Do-Hyoung Park of MLB.com reports.
Garver went 1-for-4 with a grand slam during the opening frame before being hit by a pitch in the 10th inning and exiting the contest. It appears he's avoided a serious injury, but he could be held out Wednesday in advance of Thursday's scheduled off day to provide two straight days to recover.
