Adelaide signs former basketball star Hugh Greenwood, who walked out on the Perth Wildcats a little over a month into a three-year contract.
The 23-year-old 193cm big man will join the Crows as a Category B rookie on a two-year deal and has been training with the club for two weeks.
Greenwood trialed with NBA outfit the Utah Jazz in May, a month after being crowned the University of New Mexico's co-MVP in his final year of college.
He has also been a part of the Australian Boomers squad for several years and captained the country's under-19 side.
A talented junior footballer, Greenwood has previously said he'd consider a move back to the sport if his NBA dream didn't eventuate.
"I am blessed and humbled to be given this opportunity by the Adelaide Football Club," Greenwood said.
"After a short visit to the club earlier in the week, the professionalism and environment of the organisation as a whole is what impressed me the most.
"I know there will be plenty of challenges and obstacles ahead for me, but as an athlete that is what excites me and drives me the most."
