Regular Jaguares captain Agustín Creevy has been named in the Super Rugby team as captain of the team to play the Waratahs in Sydney on Saturday.
Jaguares Super Rugby coach Raúl Pérez has made four changes to the side that was beaten by the Kings last weekend.
Creevy takes over the captaincy from crum-half Martín Landajo and replaced Julián Montoya in the front row.
Alongside Creevy Enrique Pieretto comes in at tighthead while Nahuel Tetaz Chaparro moves to loosehead.
Benjamin Macome comes into the side replacing Matías Alemanno who was injured last weekend.
In the backs Jerónimo De la Fuente returns to the side at the expense of centre Bautista Ezcurra who drops out.
