Lavezzi to miss Copa final after fracturing elbow

Ezequiel Lavezzi will miss the Copa America Centenario final after it was confirmed he suffered an elbow fracture in Argentina's semi-final win over the United States on Wednesday.

Lavezzi, who scored the game's opener inside four minutes, was forced off in the second half of their 4-0 win against USA after landing awkwardly when he tumbled over an advertising board in Houston.

The Hebei China Fortune forward leapt up for a header but was too close to the hoardings, appearing to land badly on his neck. 

After being taken away on a stretcher, medics confirmed the 31 year-old suffered a radial fracture in his left elbow. 

The injury will need surgery, ruling Lavezzi out of the Copa America final on Monday (AEST).

Argentina will be hoping to end their 23-year wait for a major trophy in the decider, where they will meet either defending champions Chile or Colombia.
