McPhee (knee) was designated to return from IR on Monday, Ryan Mink of the Ravens' official site reports.
McPhee has been out since Week 11 against Cleveland and went on injured reserve Nov. 20 after having arthroscopic surgery on his knee. He now has a 21-day window to practice with the team before either being activated or left on IR for the remainder of the regular season . However, McPhee could return as soon as Sunday against the Bengals if he's deemed ready through his performance in practice this week.
