O'Neill was removed from Tuesday's game against the Phillies with right wrist discomfort, Jake Rill of MLB.com reports.
O'Neill went 0-for-2 during Tuesday's game before his wrist forced him to exit during the sixth inning. The Orioles will likely provide more details on the severity of his injury once they get a closer look at him, but he can be considered day-to-day for the time being.
