Preston, who has links to the LaMelo Ball camp, was signed as an injury replacement for rookie Sam Froling three weeks ago.

The acquisition of a four-man raised some eyebrows when he was added to the Hawks roster alongside American journeyman Darington Hobson.

The club confirmed his departure on social media on Tuesday, citing "family reasons" but it is understood the former Oak Hill Academy student was AWOL from three different training sessions with the club, with coach Matt Flinn putting his foot down on Monday.

He made three appearances for the club, going 1-11 from the field on debut against Melbourne United a fortnight ago.

He had seven points before fouling out in just six minutes on the floor against Adelaide last week - one of the fastest in league history.

He had six points against New Zealand on Sunday but did not show for recovery, prompting the club to cut ties.

It continues a nomadic career for the California native that saw him play for five different high schools and three different NBA affiliate franchises after a brief professional stint in Bosnia.

Froling started running on his injured ankle last week and is on track for a return to the floor in early January.

The Hawks broke for Xmas on Monday and will return to training on Boxing Day ahead of Saturday's road clash with South East Melbourne.
