Witherden was elevated to the AFL Academy in 2016 after a promising second half to 2015 with the Geelong Falcons in the TAC Cup. Playing across half back or through the midfield, Witherden has the ability to pinpoint passes with his elite kicking. Witherden was set to represent Vic Country in the 2016 NAB AFL Under 18 Championships but a broken leg suffered playing for Geelong College ended his season prematurely. Following a diligent approach to his rehabilitation, the Brisbane Lions selected Witherden with pick 23 at the 2016 NAB AFL Draft. Witherden’s ability to play both attack and defence will be helpful for the improving Lions.
Witherden’s debut came in round 14 against GWS during the 2017 season. Impressing with 20 disposals, Alex not only held his position, he developed into an integral player in the Lions’ backline for he remainder of the season. His 2017 season saw him play 9 games, averaging 23.6 disposals a game, including a huge 15.9 kicks. Alex will look towards the 2018 season where he hopes to further consolidate his experience and development.
