Argentina have called up River Plate midfielder Enzo Perez as a last-minute replacement for injured Manuel Lanzini, the Argentine Football Association said on Saturday.
The 25-year old was set to play a crucial role for Argentina in the World Cup this summer.
The South Americans are in Group D with Nigeria, Croatia and Iceland.
Argentina could well have done with a supplemental talent like the Hammers man, too, with forwards Lionel Messi, Sergio Aguero, Gonzalo Higuain and Paulo Dybala crying out for a steady supply of ammunition. All eyes will now be on Argentina coach Jorge Sampaoli to see who will be replacing Lanzini in the squad.
Lanzini will be in recovery for several months and is a serious doubt for the start of West Ham's 2018/19 campaign in the Premier League.
They will now have to deal with a new player being drafted in after Lanzini's serious injury.
