Vidal retained in Chile squad despite injury
The Juventus midfielder had arthroscopic surgery on the lateral meniscus of his right knee last month in a bid to be fully fit for the finals in Brazil.
Although Vidal has yet to play since going under the knife almost four weeks ago, he remains part of coach Jorge Sampaoli's plans.
Chile's 23-man selection was announced on Sunday, with seven players cut from the original party named by Sampaoli on May 13.
Key midfielder Matias Fernandez had already seen his World Cup dreams dashed by an ankle injury.
Experienced centre-back Marcos Gonzalez will also miss out following a lack of playing time in recent months.
There is also no place for O'Higgins duo Paulo Garces and Pablo Hernandez, with Enzo Andia, Rodrigo Millar and Gustavo Canales the other players to have been left out.
Chile face Northern Ireland in Valparaiso on Wednesday, in their final friendly before the World Cup.
Sampaoli's men face a daunting group in Brazil, having been drawn alongside Spain and the Netherlands - the teams who contested the 2010 final - together with Australia.
