Frustrated Brumbies coach Dan McKellar has declared the axe is looming for some of his underperforming players.
The first-year Super Rugby mentor blasted his team for blowing a 14-point lead against Melbourne on Saturday night.
The Rebels' unbelievable 27-24 win ends any finals aspirations the Brumbies had as they sit 14th on the overall ladder, only in front of the Sunwolves.
McKellar believed his side "lost the unlosable" and it wasn't good enough, forecasting changes for the Brumbies' two-game stint in South Africa.
"You review it and you've got to start learning and some aren't doing that, so I'll have to make changes. It's frustrating," McKellar said.
"It's about 2018 and not about 2019 or beyond that but we've got to start to learn from the mistakes that we're making."
A "gutted" Brumbies co-captain Christian Lealiifano, who was returning after a two-game spell, echoed McKellar's thoughts.
"We spoke out there about momentum shifts and how we're going to manage them and I just feel like we're banging our heads up against a brick wall," Lealiifano said.
We've got to do something. Whether it's a big change or adjusting something, we're sitting here really frustrated with just seeing the same stuff."
Prop Scott Sio will be in doubt after failing a head injury assessment in the first half, as will flyhalf Wharenui Hawera, who went off with a leg injury.
The Brumbies' next game is against the South African conference leading Lions in Johannesburg.
