McPhee (knee) was placed on the reserve/COVID-19 list Tuesday, Ryan Mink of the Ravens' official team site reports.
McPhee tested positive for COVID-19 Tuesday and will now enter league protocols. The news comes at an inopportune time for the 33-year-old, as he was just designated to return from injured reserve Monday after being placed on IR in late November. The Ravens will likely now have to wait at least another week before he can return to practice.
