The Brumbies have made one predictable change for their Super Rugby semi-final against the Jaguares, promoting Lachlan McCaffrey to No.8 in place of the injured Pete Samu.

Coach Dan McKellar has otherwise stayed with the starting team who demolished the Sharks in the quarter-finals for the match in Buenos Aires on Saturday morning (AEDT).

Lock Murray Douglas takes McCaffrey’s spot on the bench.

Samu, who bagged two tries in the quarter-final, was the only Brumbies forward to have played every game this season, along with prop James Slipper.

Captain Christian Lealiiano will make his 150th appearance for the Brumbies in what could be his final game before leaving for Japan.

The Brumbies come into the game on a seven-match winning run, although their Argentine opponents can boast 10 wins from their last 11.

Brumbies: Tom Banks, Henry Speight, Tevita Kuridrani, Irae Simone, Toni Pulu, Christian Lealiifano (capt), Joe Powell, Lachlan McCaffrey, Tom Cusack, Rob Valetini, Sam Carter, Rory Arnold, Allan Alaalatoa, Folau Fainga’a, Scott Sio. Res: Connal McInerney, James Slipper, Les Makin, Darcy Swain, Murray Douglas, Jahrome Brown, Matt Lucas, Tom Wright.
