Warner Bros. Discovery said Friday night that it is abandoning its regional sports network business. 

AT&T SportsNet has deals with the Houston Rockets, Portland Trail Blazers and Utah Jazz in the NBA.

The SportsNet announcement comes on the heels of news that Diamond Sports Group is also prepping to file for bankruptcy this spring. DSG owns and operates the Bally Sports regional networks and has the local television rights for over 40 MLB, NBA and NHL teams. 

While WBD is attempting to exit from the RSN business, they are also negotiating with the NBA on extending its national television deals.
