Owen Hargreaves has been ruled out of Sir Alex Ferguson’s pre-season trip to South Africa after suffering a recurrence of knee injury that has been bothering him since his big time 20.2 Million Pound transfer from Bayern Munich last summer.

The injury limited the Canadian born midfielder to just 23 appearances over the 2007/08 season and there is a worry that this could be something that will have to be addressed throughout the rest of his career.

United is off on a 10 day tour of South Africa that is meant to promote that upcoming 2009 Confederation Cup and the 2010 World Cup.
