UPDATE: West Coast midfielder Tom Swift has quit the club to pursue medicine at university after four years with the Eagles.
Swift, 22, told his manager of his decision on Friday afternoon before advising West Coast coach John Worsfold of his shock decision.
Swift is out of contract at West Coast, but is understood to have been on the verge of receiving a one-year extension offer.
"The opportunities I see myself having outside of football outweigh the benefits I’m going to gain from a football career,” Swift told The West Australian.
“A change in lifestyle is something I’ve always desired and following my academic pursuits and making the most out of them.
Swift will attend the University of Western Australia next year and is unsure whether he will even play for his WAFL club, Claremont.
He admitted agonising over the decision.
“I feel like I’ve come to a bit of a crossroad where if I let too much time elapse I won’t have those opportunities any more,” Swift said.
“You never make a decision being 100 per cent sure. There’s still a voice in the back of my head saying I’ve made the wrong decision, but it’s something I’ve got to live with now.”
