The NBA has banned former Kings assistant director of scouting Jack Mai for betting money on league games, Yahoo! Sports has learned.

Mai bet on Sacramento's games in addition to other clubs.

The league informed teams in a memo on Wednesday that an investigation revealed Mai bet on games "limited to small amounts of money among acquaintances and there is no evidence that he ever attempted to use his position with the Kings to influence the outcome of any NBA game."

A league source told Yahoo! Sports that Mai bet on the Kings games for years, "some for, and some against."
