After a week's break the Rugby Championship is back with plenty still on the line.
In case you need a reminder of what we last saw, the Springboks came from behind again to make it four straight wins against the All Blacks, while the Wallabies were smashed by the Pumas in Argentina to fall to a record loss.
This week the Springboks hit the road and take on the Pumas for a battle to secure the Rugby Championship, while it's a fight in Sydney for the losers to avoid the wooden spoon and -- the Bledisloe Cup is also on the line, too.
Read on as we bring you the latest team news below and look ahead to the Round 5 clashes.

Team news: The Wallabies have welcomed back Tom Wright and Hunter Paisami into their backline, while Noah Lolesio has a new halves partner in Nic White. Coach Joe Schmidt said there was some tiredness across his Australian squad following the record-breaking loss in Santa Fe, which brought about White's inclusion in particular.
Arguably the biggest addition however comes in the form of Fraser McReight, who has missed all four Rugby Championship games this season because of a thumb injury. McReight has replaced Carlo Tizzano in the No. 7 jersey, despite Schmidt saying how impressed he'd been with the Force No. 7's efforts in his four Tests to date.
All Blacks coach Scott Robertson has meanwhile reinstated some backline firepower of his own, with Caleb Clarke back from injury on the left wing and Beauden Barrett back into the starting side at fullback. New Zealand also welcome back Ethan de Groot up front with Tamaiti Williams dropping back to the bench.
