Cole has scored three goals in 20 games this season
Chelsea midfielder Joe Cole has been ruled out for the rest of the season after suffering a serious knee injury.
The 27-year-old England international ruptured anterior cruciate ligaments in Wednesday's 4-1 FA Cup win at Southend.
Blues boss Luiz Felipe Scolari said: "I am very sad for Joe to have suffered this injury and I am disappointed to have lost a very important player."
Cole will also miss England's World Cup qualifier with Ukraine in April and the friendlies with Spain and Slovakia.
He is also a doubt for the June qualifiers against Kazakhstan and Andorra.
Chelsea and England skipper John Terry added: "We're all behind Coley to get fit as soon as possible. He's going to be a big miss for us and I keep on saying he's the one who really opens things up in tight moments.
