James Slipper is poised to equal the record for the most test caps for Australia in rugby, with his 139th cap anticipated during the clash against Argentina in Santa Fe. Slipper, who has been named among the replacements, will tie the mark set by legendary scrum-half George Gregan. Coach Joe Schmidt praised Slipper's dedication, emphasizing the team's collective effort to commemorate this milestone. Alongside Slipper, the Wallabies will see new faces, including Max Jorgensen starting on the right wing for the first time after his 20th birthday. The match will also feature Ben Donaldson at flyhalf, replacing Noah Lolesio, who is out due to injury. This game marks a significant occasion for Slipper as he aims to further solidify his legacy within the Wallabies' history.
