30-year-old Vidic has had successful knee surgery in the past 24 hours and will now begin his rehabilitation.
"Nemanja Vidic has had a meniscus operation on his right knee and will be out for around eight weeks.
Manchester United manager Sir Alex Ferguson rested Vidic as a precautionary measure at the weekend after he complained of tightness in his knee. However, further medical investigation revealed the underlying problem.
The central defender was operated on this week and will be sidelined for about eight weeks."
