The NBA salary cap is expected to decline "anywhere between $3 million and $12 million" for next season, sources told Connor Letourneau of the San Francisco Chronicle. 

The league reportedly missed its revenue projections by $1.5 billion due to a combination of the shutdown, cancellation of games, and finishing the season without fans. 

It was reported on Friday that the NBA could hold up to 40% of player salaries for the upcoming season in escrow to offset anticipated losses due to having a limited amount of fans or no fans altogether.

The withheld salary would be roughly $1.6 billion based on a $4 billion projected salary for next season.

The league is also targeting a December 22nd start date, which could generate an extra $500 million in revenue.
