MORE SCANS: David Pocock receives medical attention to his knee during round three of Super Rugby against the Western Force.

ACT Brumbies superstar David Pocock faces another heartbreaking season-ending injury with fears he may need more surgery on his anterior cruciate ligament.

Pocock will fly to Brisbane on Tuesday for more scans after injuring last weekend the same knee he had a reconstruction on.

Pocock has been ruled out of the Brumbies' clash with the Wellington Hurricanes on Friday night and the club admits he may not play again this season.

Pocock ruptured his anterior cruciate ligament after just three games with the Brumbies last year.

He re-injured the same knee in the win against the Western Force last weekend.

Pocock had scans in Canberra, but they were inconclusive and he will fly to Brisbane to meet surgeon Peter Myers.

Myers operated on Pocock's knee almost exactly 12 months ago.

The Brumbies will know later Tuesday whether Pocock's anterior cruciate ligament is fine, or if he will be missing for the rest of the year.

If Pocock is ruled out for the season, the Brumbies will contemplate recruiting another back-rower.

Star Fotu Auelua is also injured and won't be back on the field until round 12.

Brumbies and Australian great George Smith could be a potential option if the Brumbies could lure him back to Canberra for another cameo stint.

Smith, a veteran of more than 100 Tests and the Brumbies' games record holder, returned to Canberra last year to tag team with Pocock.

But just one game into Smith's return, Pocock injured his knee and Smith took over the openside flanker duties for the season.

"David will fly to Brisbane ... the MRI scans [in Canberra] showed some different things so he's going to meet with Peter and we'll know more from there," Brumbies director of rugby Laurie Fisher said.

"We just need some clarification there ... Peter did the initial surgery and he will know whether the ACL is all right or whether it has to be re-done."

Losing Pocock would be a cruel blow to the Brumbies' bid to make the Super Rugby finals again.

Pocock is regarded as one of the world's best flankers, when fit.

The Brumbies will call on Jarrad Butler, Lachlan McCaffrey and Jordan Smiler to fill the hole left by Pocock against the Hurricanes.

Pocock left the field with 10 minutes to go in the win against the Force.

Centre Pat McCabe also left the field injured and went to hospital in a neck brace.

But McCabe, who has broken his neck twice since November 2012, was cleared of any structural damage.

Fisher said the Brumbies would wait to get a decision on Pocock's injury before investigating whether the club recruits another specialist openside flanker.
