Instead of easing concerns over their depleted forward line, Brisbane Lions skipper Jonathan Brown unwittingly revealed more potential headaches ahead of their AFL clash with the Kangaroos.

After digesting the news that key forward Daniel Bradshaw could be out for up to three weeks with a hamstring tear, Lions coach Michael Voss had big plans for Lachlan Henderson to step up against North Melbourne at the Gabba on Saturday night.

However, Brown on Tuesday claimed Henderson was also on the injury list with a foot complaint.

It would be another blow for a Lions side already sweating on the fitness of dangerman Jared Brennan (ankle).

To the surprise of reporters in Brisbane on Tuesday, Brown rated Henderson a "touch and go" prospect for the Lions.

"He's got his own injury concerns himself so I'm not sure whether he'll be available," he said.

"More of a hot spot, not a stress fracture (of the foot).

"Timmy Notting and James Polkinghorne have done a good job there ... and we know that (ruckman) Mitch Clark can go forward and hopefully Jared Brennan comes up.

"Hopefully we'll still have a few options."

Brown - second in the Coleman Medal count with 55 majors from 16 games - said he would not feel extra pressure to score without Bradshaw.

"He's a big loss Braddy. We're going to have to re-configure the forward line a little bit, and hopefully find another goalscoring option," Brown said.

"(But) I'm pretty confident with our forward set up.

"We're starting to get some good options around the forward line, not just Braddy and myself, and we're starting to get a better spread of goalkickers.

"Losing one of our key position players hopefully won't affect us as it might have in the past two or three years."

The Lions are in the top five with a 10-6 record following last round's gutsy 15-point away win over Fremantle.

They are now on track to make the finals for the first time since 2004 - when their run of three straight premierships came to a halt against Port Adelaide.

While the Lions are just two wins away from the magical 12 victories they believe will guarantee top eight action, Brisbane weren't taking the lowly Kangaroos for granted.

"We should be confident. We're on our home deck, we've had a good record here this year," he said.

"North Melbourne always show a tremendous amount of spirit, they did that on the weekend, and fought back against Richmond (to draw).
