England national team member and the leader of the Premier League club's security Michael Carrick dropped out of the lineup for a month due to a calf injury.
Manchester United acquired this talented 25-year-old player from Tottenham in the summer for £18.6 million. The defender has been a key player for the "Red Devils" main team this season, but so far has not scored any goals.
The Englishman did not travel to Birmingham with the team on Saturday, where they will face Aston Villa, and will not be able to help his partner in the midfield, Paul Scholes.
The team's head coach, Sir Alex Ferguson, has not yet revealed the seriousness of M. Carrick's injury, but it is believed that he will be out of action for four weeks.
Before moving to the Manchester club, M. Carrick had already suffered a similar injury and missed only the first season match with Fulham. The defender participated in all other matches except the one against Middlesbrough.
