AS Monaco striker Radamel Falcao tore the anterior cruciate ligament in his left knee and could be out of action for six months, jeopardizing his chances of competing in the World Cup for his native Colombia.
Portuguese surgeon Jose Carlos Noronha, a top knee specialist who examined the 27-year-old star in Porto after he was injured during a French Cup match Wednesday against fourth-division side Monts d'Or Azergues Foot, confirmed the news in remarks to Efe Thursday.
Falcao scored a goal in Monaco's 3-0 win.
The Colombian international sustained the injury when he was tripped up from behind by defender Soner Ertek, and he was visibly in pain while being carried off the field on a stretcher.
Falcao will now race against the clock to recover in time for the World Cup, which begins in Brazil on June 12.
Colombia, which qualified for soccer's biggest showcase for the first time since 1998, is in Group C along with Greece, Japan and the Ivory Coast.
The Colombian striker also has played a big role in Monaco's success this season. The club is currently in second place in the French league behind Paris Saint-Germain. EFE
