Quijada was placed on the 10-day injured list for undisclosed reasons Wednesday, Andersen Pickard of MLBDailyDish.com reports.
Due to privacy concerns, the Angels wouldn't legally be allowed to specify whether or not Quijada's absence is due to COVID-19. When healthy, Quijada isn't expected to fill a significant role in the Angels' bullpen, as he struggled to a 5.76 ERA and a 1.79 WHIP in his 29.2-inning big-league debut for the Marlins last season.
