Monaco says Colombia striker Radamel Falcao will have surgery on his left knee, putting him in danger of missing the World Cup.

Falcao was stretchered off the field after damaging his anterior cruciate ligament during a French Cup match on Wednesday when he was tackled by Chasselay center half Soner Ertek.

Monaco says "the player will have surgery in next few days. Doctors will do everything possible to speed up recovery."

ACL injuries can take several months to heal. The World Cup in Brazil starts on June 12, and Colombia's first match is on June 14 against Greece. Japan and Ivory Coast are also in Group C.
