Rio 'out for up to three weeks'
Published 23:01 09/02/11 By David McDonnell - EXCLUSIVE
Rio Ferdinand is likely to be out for up to three weeks for Manchester United because of a calf strain.
Ferdinand, who will miss this weekend's Manchester derby, was hurt in the warm-up before United's 2-1 defeat at Wolves last Saturday.
Sir Alex Ferguson initially said Ferdinand would be out for "two weeks" with the injury, but it has emerged the central defender could be sidelined for longer.
Despite intensive treatment by United's medical staff, the date they have given for Ferdinand's likely return is the Premier League trip to Wigan on February 26.
As well as the big clash with City, that would see Ferdinand miss the FA Cup tie with non-league Crawley Town - a game he was always likely to sit out - and the first leg of the Champions League last-16 tie away to Marseille.
United are taking no chances with Ferdinand's fitness and do not want to rush him back too early, risking further injury, with key Premier League games away to Liverpool, Chelsea and Arsenal to come on the title run-in.
