The Cards have reinstated the unvaccinated players and just announced a new trade today:
7/28/22: Returned IF Corey Spangenberg, who had been selected as a COVID-19 injury substitute, to AAA Memphis. Returned C Ivan Herrera and OF Conner Capel, who had been added as COVID-19 injury substitutes, to AAA Memphis. Activated C Austin Romine, 3B Nolan Arenado and 1B Paul Goldschmidt from the Restricted List. 40-man roster now full.
The rules allowed the Cards to remove Spangenberg from the 40-man roster without placing him on waivers and also allowed the club to send Herrera and Capel back to Memphis without using one of the five allowable options this season.
