David Pocock has undergone another knee reconstruction that will rule him out for the rest of the 2014 season.
An arthroscopy earlier on Wednesday confirmed the Brumbies flank had re-ruptured his anterior cruciate ligament during last Saturday's match against the Force.
It was the second ACL reconstruction he has undergone in as many seasons after a rupture forced him from the field in round four last year.
'Having worked so hard to get himself back to peak physical condition over the last 12 months it's impossible not to feel for David,' said Brumbies director of rugby Laurie Fisher. 'Only yesterday he was speaking about how much enjoyment he'd been getting out of his rugby this year so to have him sitting out the rest of our campaign is bitterly disappointing for him and the rest of the team.
'What we must remember is that David is still young and will have more opportunities to play professional rugby in the future. Guys like Ben Mowen and Christian Leali'ifano are living proof that you can make a successful comeback from a recurring injury and I'd expect to see David bounce back in the same way.'
Jarrad Butler, Lachlan McCaffrey or Jordan Smiler will replace Pocock in the Brumbies' starting line-up.
