GEELONG pair Josh Walker and Jarrad Jansen have joined the Brisbane Lions for a future third-round draft pick.

On Monday morning, Lions list manager Peter Schwab told NAB AFL Trade Radio the deal would soon be formalised, which it was several hours later.

Walker was a handy contributor with the Cats in 2015, kicking 19 goals in 16 matches to take his game's tally to 33.

He provided good support to Tom Hawkins but his options appear limited if Nathan Vardy and Mitch Clark are fit enough to play regular senior football in 2016 and Zac Smith is traded from Gold Coast to the Cats.

Jansen has not yet played a senior game for the Cats but will have greater opportunities as an inside midfielder with the Lions.

He was in the Cats' extended squad for the game against Adelaide that was cancelled after the death of Crows' coach Phil Walsh, and finished runner-up in the Cats' VFL best and fairest. 

However he found it hard to force himself ahead of Cats' midfielder George Horlin-Smith in the race for that inside midfielder to support Patrick Dangerfield, Joel Selwood and Cam Guthrie.

"Both players are looking to play regularly at AFL level and they feel this is most likely to happen at Brisbane," Geelong’s general manager of football Steve Hocking said.

"With the strengthening of our list in this period, and the Lions desire to add Josh and Jarrad, it was a good outcome for all parties."

Schwab virtually ruled out the prospect of Richmond's David Astbury joining the Lions. Astbury has a year to run on his contract at the Tigers.

He also said Collingwood was yet to make an offer for James Aish but it would need to offer more than a second-round pick to secure the talented young midfielder.
