THE DOOR has been left ajar for former Sydney Swans premiership player Nick Davis at the Brisbane Lions ahead of next week's NAB AFL Pre-Season Draft.

New coach Michael Voss said he had not drawn a line through Davis' name despite the ex-Swan not being sighted at the Lions' off-season training.

Davis -- delisted by the Swans -- was invited by Voss to attend pre-season training but his absence from a three-day camp at Stradbroke Island in November appeared to signal the end of his 168-game career.

However, Voss refused to rule out grabbing Davis with their No.5 draft pick.

He said the club was looking at three possible options next week - snapping up a crumbing forward like Davis, an extra midfielder or a ruckman like delisted St Kilda player Michael Rix.

"Nick fits into that (crumbing forward) category that he can kick goals and he knows where they are," Voss said.

"Inside 50m it's rare to find players who can find the ball in that area of the ground because it's just so congested.

"Do we go down that path, or do we decide to go for an extra midfielder, or do we put journeyman ruckman in place?

"We have a couple of different things that we're trying to think about."

Despite not ruling out Davis, it is Rix, 27, that appears to be in the box seat for selection by the Lions.

Rix was part of St Kilda's biggest clean-out in eight years at the end of the 2008 season, one of eight players delisted in October.

Rix would add welcome depth to a Lions ruck division relying on Jamie Charman and youngster Matthew Leuenberger.

"I guess Michael Rix has been trialled and obviously listed at St Kilda so he's one that springs to mind," Voss said.

"We've got three ruckmen now but (draftee) Bart (McCulloch) obviously is a bit younger and Michael has got a little bit more experience."
