O'Neill was scratched from the lineup for Tuesday's game against the Pirates while dealing with the side effects of his COVID-19 vaccination, Katie Woo of The Athletic reports.

EDGE Analysis

The Cardinals could place O'Neill on the COVID-19 injured list if they wanted to, but no such transaction has been made yet. O'Neill could potentially be available off the bench and could return as soon as soon as Wednesday. Edmundo Sosa entered the lineup in his absence, taking Tommy Edman's spot at second base and bumping Edman to the outfield.
