The last of the injury reports are almost in for the wounded Brisbane Lions but coach Michael Voss reckons this weekend's AFL clash with Geelong will reveal the most about his side.

There was mixed news for Voss from medical staff following their third straight loss.

Fears that Jared Brennan had broken his leg were allayed, but the star utility will still miss four to six weeks with an ankle injury.

However, Voss is still sweating on scan results to determine if Josh Drummond can undergo the radical Ligament Augmentation and Reconstruction System (LARS) surgery on his damaged left knee.

Another key casualty of the Lions' 13-point loss to Fremantle, Drummond will still miss the rest of the season even if allowed LARS surgery over a regular knee reconstruction.

His injury list may be updated but Voss reckons he will know exactly what makes his side tick following their showdown with the reigning premiers.

Rather than be daunted by the prospect of his depleted team taking on a merciless Geelong, Voss sounded like he couldn't be happier.

"It's great, for us, when you don't have it all on your own terms," Voss said.

"These are the times when you have to find something inside you.

"Sometimes you have it presented nicely, with a ribbon on top, but sometimes you don't and that's us at this point in time.

"As a competitive football team, these are the weeks that you find something out about our group - and we get that chance.

"So I'm looking forward to the week."

In other injury news, ruckman Mitch Clark (groin) and Andrew Raines (calf) were only rated "50-50" chances to line up against the Cats.

But at least some of the defensive cavalry are returning in the Lions' time of need.

Defenders Daniel Merrett and Joel Patfull (both hamstring) are likely to be fit for the Gabba clash while centre half-back Matt Maguire is back after serving a one-match ban.

The Lions may have beaten the Cats - albeit a heavily depleted version - in their last meeting in 2009, but Voss was well aware of the enormity of the task ahead - especially after witnessing them ground a high flying Swans outfit on Sunday.

"They were what I expected," Voss said.

"We've had all the fairytale teams that we look for, like Collingwood coming up and Fremantle and Sydney and the like.

"But I said it a month ago and I said it a year ago - Geelong are up there, don't forget about them."
