The NBA has sent a memo to all 30 teams on Friday indicating that the one-and-done rule could be eliminated as early as 2021.
The memo does not mention the one-and-done rule by name, but it is meant to remind teams the league and the players union could agree to scrap one-and-one before the expiration of the current collective bargaining deal in 2024.
The first draft in which the rule is changed will surely be loaded with the best prospects from two straight high school classes.
The memo serves as something of an advisory to teams who might think about trading away future first-round picks in the lead-up to Thursday's draft.
The league instituted the one-and-done rule in 2005, but it has since been met with criticism on many sides of the issue.
The league will discuss the issue further during annual meetings at Summer League in Las Vegas, the memo says.
