The 26-year-old signalled his intent to return to Australia after moving back home to Ireland in 2020 due to homesickness, plying his trade in Gaelic football with boyhood club Tyrone.
However, the 26-year-old won't be going back to The Hangar on his arrival back down under, with the Lions reportedly the front runners according to The Herald Sun's Jay Clark.
AFL TRADE NEWS: Roos to consider offers for No.1 pick
When the news broke that McKenna would be seeking a route back into the AFL, Geelong were flagged as the club sounding out the most interest in the dashing defender's services to complement their star-studded lineup.
But with Daniel Rich being 32 years of age, a replacement for the reliable defender could very well be the Irishman, with McKenna's run off halfback a big asset for Brisbane as they look to keep going at the top-end of the ladder.
Port Adelaide are also linked with the halfback and for good reason considering gut-runner Karl Amon has opted to exercise his rights as a free agent , declaring Hawthorn as his preferred destination.
Prior to his departure back home, McKenna was a big part of Essendon's setup for the four seasons before he decided to head back home.
McKenna played 79 games for the Bombers after being taken at Pick 62 in the 2014 Rookie Draft, finding a home across halfback and being one of the speediest players in the league.
In his final full season with Essendon in 2019, he put up some pretty impressive numbers averaging 20.8 disposals and 4.5 rebound 50s as well as being ranked first across the entire competition for bounces.
The 26-year-old will be able to be scooped up through the National Rookie Draft or the Supplementary Selection Period (SSP) over the off-season and will reportedly have til November to make a decision on his future.
