Manchester United's Sergio Romero has been ruled out of this summer's World Cup after the Argentina goalkeeper suffered a knee injury.
Argentina's official Twitter feed announced the news late on Tuesday -- a day after the country's 23-man squad was announced.
[DESAFECTADO] Sergio Romero sufrió hoy un cuadro de bloqueo articular en su rodilla derecha que lo dejará fuera de la convocatoria.

A statement on the Argentinian Football Association's website read: "Argentina goalkeeper Sergio Romero will be removed from the list of 23 players who will participate in the 2018 World Cup in Russia.
"The player of Manchester United today suffered a joint blockage in his right knee which requires surgery."
Later on Tuesday, another tweet from the Argentina account said that Tigres' Nahuel Guzman would be Romero's replacement for the team headed for Russia.
Chelsea's Willy Caballero and Franco Armani were the other goalkeepers named in Jorge Sampaoli's squad.
Romero has made 94 career appearances with Argentina, the seventh-most in team history and most by a goalkeeper.
