Centre Isaac Humphries has become the latest Australian to join the NBA, signing with the Atlanta Hawks until their season ends next week.

"Absolute dream come true...Wow i'm an NBA player!," Humphries tweeted.

The 21-year-old has most recently been playing in the NBA's G League with the Erie BayHawks where he averaged 11.3 points, 6.9 rebounds and 1.1 blocks a game.

After a US college stint with Kentucky, Humphries spent the 2017/18 NBL season with the Sydney Kings and was named rookie of the year.

Humphries, on a 10-day contract with the Hawks, joins 12 other Australians in the NBA, led by Philadelphia's 2016 No.1 draft pick Ben Simmons.
