Madubuike (illness) was placed on the reserve/COVID-19 list Wednesday, Ryan Mink of the Ravens' official site reports.
Madubuike is the latest Raven to end up on the COVID list. With Calais Campbell's (thigh) status for Sunday against the Bengals also up in the air, the Ravens could be light on the defensive line. Madubuike could get cleared in time for Sunday if he is vaccinated and able to produce two negative tests more than 24 hours apart.
