A strong Argentina team will be captained by hooker Julian Montoya, six days after the hooker featured in the Leicester side that lost the English Premiership final to Bath.
Santiago Carreras is at fullback with Tomas Albornoz at first five-eighths, while Saracens flanker Juan Martin Gonzalez is in a back row also featuring the experienced Pablo Matera.
“We know all their players and we expect them to be playing hard,” said Argentina coach Felipe Contepomi, whose side are ranked fifth in the world.
“They miss some cohesion or maybe not because they are such top players they can click in one moment.”
The 30-year-old Itoje, previously appointed as Lions captain for the upcoming three-Test tour of Australia, skippered England to second place in this year’s Six Nations.
The Lions, made up of leading players from England, Scotland, Ireland and Wales, play their first Test in Australia on July 19 at Brisbane’s Suncorp Stadium.
