Port Adelaide have today lodged paperwork with the AFL to claim Brisbane Lions midfielder Tom Rockliff as a restricted free agent.

The Lions now have three days to consider their options in regard to the offer made by the Power, whether to match the offer and retain the 27-year-old or decline to match and allow the move to Port Adelaide.

Rockliff has played 154 games for the Lions since joining the club via the 2008 pre-season draft and is a two-time winner of the Murray-Merrett Medal.
