Brisbane Lions midfielder Tom Rockliff will become a restricted free agent at season's end, and is set to weigh up his future with a number of clubs keen on his services.

While it was reported last week that Port Adelaide have now entered the race to sign Rockliff, Damian Barrett toldย Triple M on Saturday afternoon that one Victorian club has already made contact with the Lions and Rockliff.

โ€œHe was contracted going into this year, heโ€™s served that contract,โ€ Barrett told Triple M's Saturday Rub.

โ€œ(He) will be seeking the market place interest again.

โ€œThe Carlton footy club has approached him and have also approached the Lions to let them know they will be speaking to Rockliff, and thatโ€™s an option for him.

โ€œPort Adelaide is (also) interested in him.โ€

With Carlton midfielder Bryce Gibbs set to request a trade back to Adelaide for the second year in a row, Rockliff would fill the void left by Gibbs, and would slot into the Blues' midfield seamlessly.

โ€œI think crucial to Carltonโ€™s interest in him is the near-certainty - in fact the certainty - that Bryce Gibbs will attempt to go again back to Adelaide,โ€ Barrett added.

โ€œHe is contracted and they may still push back on that, but if that does go down a path that is different to last time they asked that question, Rockliff is there as a back-up option.โ€
