Witt (undisclosed) was removed from Monday's game against the Giants in the fifth inning, Anne Rogers of MLB.com reports.
Witt was listed in the starting nine Monday after sitting out Sunday due to back tightness, though it's unclear if the back issue is what prompted his removal from the series opener. Nick Loftin was deployed at shortstop to take over for Witt. The star shortstop can be considered day-to-day until the Royals have more information to share on his availability going forward.
