Argentina striker Gonzalo Higuain, who has had an ankle injury for the past month, is his team's only major worry for their World Cup opener against Bosnia-Herzegovina at the Maracana on Sunday.

In Thursday's training session, Napoli striker Higuain was replaced by Paris Saint-Germain's Ezequiel Lavezzi. Inter Milan striker Rodrigo Palacio was also on the sidelines on Thursday after suffering an ankle injury in the 3-0 warm-up win over Trinidad last week. Argentina are in Group F at the World Cup along with Bosnia-Herzegovina, Nigeria and Iran.
