The biggest holdup to the NBA announcing expansions teams is the prolonged sale of the Boston Celtics, according to Howard Beck of The Ringer.
The league is looking for the Celtics to sell at around $6 billion to establish a baseline fee for expansion teams.
Bids to purchase the Celtics are reportedly coming in under the $6 billion mark.
Sources add that the expansion process has slowed down, with owners and league officials thinking more long-term about financial and competitive implications.
It could also take 3-5 years from the start of the expansion process to a team making its debut on the court.
