The free agency period has begun allowing clubs to sign players from rival teams.

Just 23 players remain from the original list of 52 free agents released in March, with Steele Sidebottom, Cale Hooker, Kieren Jack and Jack Watts among the stars who re-signed with their clubs.

Courtenay Dempsey is currently an unrestricted free agent.

List and Recruiting Manager Adrian Dodoro said a decision on the 29 year old’s future may not be reached until after the trade period.

“What we’ve said to Courtenay, and we’ve been transparent with him and all the guys who are out of contract, is we’ll get through trade period and see what happens,” he told Trade Radio.

“We’ve got an issue with list spots.  People forget that you’ve only got 40 primary list spots and four rookies. 

“That’s probably one of the guiding factors in determining who stays at the Club going forward.

“We’ll get through the trade period and see if we acquire talent and what the numbers look like.”

The free agency period closes on Sunday, October 16, at 5pm.

How it all works

A player has served seven seasons or less of AFL football at one club, and is now out of contract.

The player is not eligible for free agency if his club wishes to retain him. He may only move clubs via a trade or the Draft. If he delists himself, he is subject to the Draft, and may be selected by any club. 

A player has served seven seasons or less of AFL football at one club, and has been delisted by his club.

The player is a Free Agent and is eligible to field offers from all rival AFL clubs.

The player must decide on the best offer of his choice from one rival club.

The player can move AUTOMATICALLY to the new club of his choice.

His original club, which chose to delist him, does not receive any compensation pick for the loss of the player.
