The England left-back sustained the injury in the Blues' 2-1 defeat to Everton in a challenge with USA international Landon Donovan. Cole will now be in a race against time to be fit for Premier League title-chasing Chelsea's last game of the season against Wigan on May 9. The 29-year-old will also be a major concern for England manager Fabio Capello as he makes plans for the World Cup finals, which begin in June. England's first game in the finals is against a USA side which is expected to feature Donovan. Before that game the Three Lions play Egypt in a friendly on March 3 at Wembley and Wayne Bridge will be a favourite to replace Cole. That could see the Manchester City player re-united with John Terry for the first time since the recent off-field revelations about the former England captain's private life.
