Wallabies lock Sam Carter's chance's of playing at the World Cup have been dented after suffering a torn medial ligament in his knee.
Scans have confirmed that the Brumbies second row is facing up to 12 weeks on the sidelines after taking an horrific knock to his knee in the first half of last weekend's Super Rugby win over the Bulls.
The 25-year-old, who was a regular member of the Wallabies team last year, will play no further part in the Brumbies' season, which is a massive loss to the side as they fight for top spot in the Australian conference.
"Like any Test player, international player, it's going to be a loss to your team," said Brumbies coach Stephen Larkham.
"He had a bit of a spell out of the game but I thought the last couple of weeks he's really played exceptionally well," adding the Wallabies assistant coach, referring to some time Carter had taken off to mourn the death of a childhood friend, who died on a rugby field recently.
"But I think we're lucky we've got good experience in the second row with Blake Enever and Rory Arnold. I think those guys have gained enough experience throughout the year to be able to fill the shoes Carts leaves."
Brumbies captain Stephen Moore has backed versatile forward Jordan Smiler to step up and help fill the gap.
"He (Carter) is a very important player for us no doubt," Moore told the Australian.
"Really strong around the tight parts of the game. Strong scrummager. Good lineout jumper.
"You miss that stuff, but I thought Jordan Smiler, who came on the other night, was one of our best players.
"That’s a really positive sign. He is not a traditional second-rower but he has played a lot there this year. He falls into that category of guys who can play a bit of everything in the back-row and also second-row. He has filled in really well for us.
"Then there is Blake Enever as well who has only had a few opportunities, but has done really well this year after coming down from the Reds.
"I think we are pretty well covered there. We have two guys who can fill the void and Rory Arnold as well. He has played really well for us this year.
"That’s what happens at this time of year. You’ve got to call on your full squad and your depth gets tested.
"We have already seen that with Matt Toomua being out for a fair while. Now we are just going to have to cover for Carts."
