The Brumbies have suffered a major blow to their Super Rugby campaign as David Pocock has had surgery on his knee and has been ruled out for the season.
Pocock had surgery on his knee on Wednesday evening in Brisbane and has been ruled out for the 2014 Super Rugby season.
The flanker's scans in Canberra were inconclusive so Pocock flew to Brisbane to see surgeon Peter Myers who reconstructed his knee in 2013 and it is believed he performed a full reconstruction on his left knee on Wednesday evening.
An arthroscopy earlier on Wednesday confirmed he had re-ruptured his anterior cruciate ligament during last Saturday's match against the Western Force.
Disappointingly for Pocock and the Brumbies, it was the second ACL reconstruction the world class flanker has undergone in as many seasons after a rupture forced him from the field in round four last year.
Director of Rugby Laurie Fisher said it was a massive blow for both the club and for Pocock.
"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," Fisher said.
"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 Lealiifano 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.
"Professionally, David has had a big impact on the way the Brumbies have prepared and approached the 2014 Super Rugby season and I'd like to see him continue to contribute to the way the team carries itself both on and off the field."
When the former Wallabies captain Pocock was injured last year the Brumbies had already called up George Smith and he took over the openside flanker duties.
Smith went on to play for the Wallabies against the British and Irish Lions in June last year.
Smith has signed a two-year deal with French club Lyon but that will only start in September so he could potentially come in as Pocock's replacement again.
